Posteriorization of the Mandibular Condyle, Compression of the Retrodiscal Tissue and Anteriorization of the Articular Disc as a cause of Neurologic Pain. Recovery of the Physiological Relationship of the Head of the Mandible with the Articular Disc. Series of clinical cases.

In this page we present some of the physiological neuromuscular foundations for the treatment of temporomandibular joint pathologies, it was also presented the importance of differential diagnosis and also the use of bioinstrumentation as surface electromyography and computerized kinesiography.

Images of patients related to their symptoms were also presented. Several etiological factors such as trauma in early childhood, especially green stick fracture, recapture of the intra-articular discs in reducible displacements, and interrelation between craniomandibular disorders and the vertebral column.

When we talk about the treatment of TMJ pathologies we have to understand that there are different approaches. The proposal for a palliative treatment is the symptomatic treatment, that is, a treatment that seeks to block the symptoms. It is given through the administration of drugs, such as analgesics, anti-inflammatory and myo relaxing drugs. The restorative approach is the treatment that seeks when possible to correct or heal what is damaged. To know what is wrong, a differential diagnosis is necessary. This diagnosis must always be made prior to the treatment proposal.

1 FOTO INIC FRONTALA 19-year-old female patient presents at the clinic with complaints of constant headache, neck pain and swelling in the face, back of the head pain and migraines.

According to the anamnesis filled out by the patient herself, in the initial consultation she reports clicks in the jaw, dizziness, ear pain and low back pain.

The patient also reports bruxism and nighttime clenching.

2 FOTO INICIAL PERFILThe patient also refers to retro-ocular pain on the right side, pain in both shoulders, and pain in the TMJ (right temporomandibular joint).

The patient reports cracks in the TMJ on the right side, sensation of ear covering, strange sounds and non-specific facial pain.

The patient claims difficulty in opening the mouth and difficulty in chewing.

Summary report written by the patient

In the middle of the year 2014, I had a routine consultation at a dentist to clean my teeth and I reported cracking and pain in the jaw, she did not pay attention, she said it was normal and it would soon pass.

Since then I started with severe headaches, dizziness, ear pain, back pain, my feet (more in  my heel), pain in my eye as well, and in days of painful crises, my right eye would hardly open and the right side of the my face all swollen (mumps type).

After this worsening we looked for an TMJ specialist who gave me an acrylic plate, thin and only for my upper teeth.

I used the splint for six months and after that all the symptoms worsened.

We looked for another specialist, who made the same acrylic plate for the upper teeth, but in a very different size, it was a thick plate.

In the beginning it helped, after six months, all the symptoms started to appear stronger.

We consulted a new specialist, who made a new type of appliance, with the wires and the blue acrylic on the side (I took it to show to you), it was what had helped me the most, using it for 24 hours, improved pain, even dizziness , but after a year of use everything returned and with all the pain still stronger, however during that one year of treatment, despite the improvements I could not make any kind of physical effort even not strong  my jaw swelled (gym, climbing stairs, picking up weight …)

In March 2017, a year and four months of use of the appliance, the professional said it was time to start “weaning”, start leaving the device and use only to sleep because I should already be good, I commented that it had gotten worse and she insisted that it was the time to be well…

It was then that we looked for another specialist, this one said that the plate in use was not suitable for the problem and made a new plate of acrylic that judged the correct one for the presented problem, was thin and of acrylic, equal to the first one I already used, only for the upper teeth, I immediately told to my mother and to him that this plate would not solve, since I had already used identical plate in previous treatment, he insisted saying yes, that was the correct one.

With the use of the device I also did  hot compresses and shocks of physiotherapy and also needles, which helped a lot in the neck muscles that hurt a lot, but this device from the beginning did not help, the headaches that felt every day were even worse, I’ve had more dizziness.

22a REGISTRO CINECIOGRAFICO INICIAL

When our proposal is a restorative treatment, we have a FIRST PHASE where the goal when possible is to heal the joint. Sometimes we can only improve it or prevent it from getting worse. Knowing what we can treat and what we cannot treat and the limitations of each individual case is very important.

To correctly evaluate the maxillomandibular relationship we should begin to consider the physiological position of mandibular rest.

Physiological rest is a concept applicable to all the muscles of the body.

The stomatognathic musculature is no exception.

The patient’s masticatory muscles were electronically deprogrammed and a new resting neuromuscular physiological position was recorded.

The patient has a pathological free space of 7.7 mm.

The patient also had a 0.6 mm mandibular retroposition.

23 oclusao DIO

Occlusion of the patient with the DIO (intraoral device)

With the record obtained with the jaw tracker an intraoral device (DIO) was made to three dimensionally reposition the mandible.

The NEUROMUSCULAR PHYSIOLOGICAL position was recorded in the form of an occlusal bite record, which was later used to make a DIO (intraoral device)

In the first phase the intraoral devices are recalibrated and / or changed according to each specific case as the jaw, muscles and TMJ improve.

24 COMPARATIVAS FRONTAIS POSTURAIS

The position of the articular disc and the presence or not of osseous edema of the mandibular condyle can only be evaluated with nuclear magnetic resonance. The result or not of the recovery of the Physiological Relationship of the Jaw Head to the Articular Disc can be evaluated by comparing the MRI after the first phase and the comparison with the initial MRI.

40 frontais comparativas

Comparative frontal radiographs of the patient before starting the treatment and at the beginning of the second phase of the treatment.

When the first phase is completed, we verify if the subsequent control images correspond to our goals set in the initial diagnosis. We know that there are cases where we can improve the case, and others where we can prevent it from worsening, and others where we can only treat the pain.

The patient did not report any symptoms from the temporomandibular joint. The comparative MRI showed the recovery of the physiological relation of the head of the mandible with the articular disc.

The electromyographic and kinesiographic records objectively showed improvement of the neuromuscular function.

In the case of positive results from the first phase we can start a second phase of treatment to remove the device that is used permanently during the first phase of the treatment. For this we can perform a three-dimensional orthodontic, a physiological neuromuscular rehabilitation or the combination of both. Always maintaining the mandibular location in balance with the muscular planes, temporomandibular joint and dental planes.

It was decided to start the SECOND PHASE of the treatment to remove the DIO (intraoral device), maintaining the physiological neuromuscular occlusion.

In this case we will move to a three-dimensional orthodontic, where the teeth are erupted to the new physiological neuromuscular position.

A three-dimensional orthodontics needs to maintain the three-dimensional position of the mandible in balance with its bone and muscle planes achieved in the FIRST PHASE, and whenever possible maintain the Physiological Relationship of the Jaw Head with the Articular Disc.
It is fundamental to understand, that this passage has to be made keeping the DIO (intraoral device, together with the different devices to be used for the dental eruption)

Patient’s statement:

After long three years of failure looking for a treatment for my problem in my city, I found Dr. Lidia in a simple Google search.

I went to her and with a proposal completely different from the others, we started the new treatment immediately.

I was in an advanced stage, where I had  headache all day, pain in the ear, swollen eye (often unable to open), right side of the swollen face too (like a mumps), pain in the neck, pain in my back and also on foot.

I had no quality of life, because I was in pain all the time. When I started the treatment in the first two days I did not feel any more headaches. With the monthly follow up, adjusting as my body asked, I no longer felt any pain in anything and I returned to a normal life.

Today I am in the middle of the second phase, super anxious to go to the end and every month that passes I feel better and better.

TMJ Study and Investigation Page. Three years of publication.

Dear friends,

At December 2014 I started the project TMJ Study and Investigation Page. At first, all its content was offered in three languages: Portuguese, English and Spanish. Due to the analysis of the webpage access statistics, at March 2015 I decided to offer the content solely in Portuguese and English.

Anyway, access to the contents of the page is still available to other researchers, professionals in the field and to those interested in the research that I develop.

Three years of publication

Nowadays, the medicine based on evidence is hierarchically stratified from top to bottom, where in the base of the pyramid we find the clinic cases, which are rarely seen as evidence.

The TMJ Study and Investigation Page had in its conception, the purpose of posting the clinic cases, which were carefully published with the documentation related to each of the patients treated at Clinica MY with pain complaints, dysfunction and TMJ pathology.

The proposition was of presenting these clinic cases and concepts in order share them, offering free access to the content along images, surface electromyographies, computerized kinesiography, scanned before and after the therapeutic process. Cases of tridimentional orthodontics and neuromuscular phisiologic reabilitation of the second phase of treatment, after the TMJ treatment, were also included.

FINAL

The TMJ Study and Investigation Page completed in the month of December, three years of life.

I remembered to celebrate on the first anniversary of the Page.

In the middle of the work with patients, teaching and publications I did not remember to celebrate the second year.

I want to celebrate these three years with you.

With this project, we have a place in the Internet that presents a line of work known as neuromuscular physiologic dentistry, which takes into account the whole body system. It is an area which acts on posture, mandibular functioning and considers the entire body system.

In order to do that, the neuromuscular physiologic dentistry aims to establish, in the patient, a position that is based on a harmonious relation between the muscles, the teeth, and the temporomandibular joints.

Child with Otalgia (earache) and Conductive Hearing Loss: when measuring makes the difference. Normalization of hearing thresholds. First and second phase. Case report.

Symptoms of mild hearing loss occurring in childhood often go unnoticed. It is vital the early detection of this deficiency.

Various physical and psychological activities of children and adolescents may be affected due to hearing impairment.

The conductive hearing loss resulting from Eustachian tube dysfunction INITIATED BY  TEMPOROMANDIBULAR DISORDERS  is OFTEN NOT CONSIDERED.

It is vital the early detection of this deficiency.

There are two general types of hearing loss, conductive and sensorineural.

Conductive hearing loss results from disruption in the passage of sound from the external ear to the oval window.

Anatomically, this pathway includes the ear canal, tympanic membrane, and ossicles. Such loss may be due to cerumen impaction, tympanic membrane perforation, otitis media, osteosclerosis , intraaural muscle dysfunction, or displacement of the ossicles by the malleolar ligament.

Sensorineural hearing loss results from otology abnormalities beyond the oval window. Such abnormalities may affect the sensory cells of the cochlea or the neural fibers of the 8th cranial nerve. Hearing loss with age (presbycusis) is an example. Eight cranial nerve tumors may also lead to such hearing loss.

11 ELET INICIAL

Surface electromyography of the patient in habitual occlusion in which are measured:

Anterior right and left temporalis

Right and left masseter

Right and left digastrics

Right and left superior trapezius

Activation of the digastrics in closure, these muscles should only must be in activity along the opening movement

During the examination there was an activation of the right and left upper trapezius even when the patient was instructed to lower his shoulders.He had activated both trapezius throughout the examination.

13

The patient reports pain in the left ear and sensation of ear blockage, especially on the left side. He also has tinnitus and DECREASE OF HEARING IN BOTH EARS.

ANY HEARING LOSS REPORTED BY THE PATIENT MUST BE EVIDENCED BY AN AUDIOMETRY.

15 AUDIOMETRIA INICIAL

An audiogram is produced by using a relative measure of the patient hearing as compared with an established “normal “value. It is a graphic representation of auditory threshold responses that are obtained from testing a patient’s hearing with pure-tone stimuli. The parameters of the audiogram are frequency, as measured in cycles per second (HZ) and intensity, as measured in dB­­­­.

The first audiometry of the patient revealed a mild hearing loss in the left ear and a moderate hearing loss in his right ear.

Symptoms of mild hearing loss occurring in childhood often go unnoticed. It is vital the early detection of this deficiency.

Hearing loss is classified as mild, in which the ear is unable to detect sounds below 40 decibels which makes it  difficult to understand human speech.

In moderate loss, the sounds below 70 decibels are not heard.

17

We recorded the mandibular rest position after electronic deprogramming, together with the information of the MRI (magnetic resonance imaging) to orient our decisions of the bite registration, for the three-dimensional construction of the DIO (intraoral device).

The patient has a pathological free space of 8.6 mm and 8 mm of mandibular retro position.

The degree of compression determinates de reaction of the patient.

The retrusion of the mandible, whether it is iatrogenically induced, or a result of malocclusion, often results in otalgia due to excessive compression of the neurovascular retrodiscal tissues. The patient’s impression is ear pain.

18

I informed the parents of the patient, that at this stage, I was only worried about the health of the patient, and focused on  improving the functions, the symptoms and controlling the conductive hearing loss.

Hearing loss resulting from Eustachian tube dysfunction, initiated by craniomandibular disorders is usually subjective.

For this reason there is a need for an objective control by audiometry.

 I explained that I would not make any orthodontic intervention at this stage to include in the arcade the canine that was misaligned and out of space. I told them  that I would take care of it later and in this case I would not have the need to extract teeth.

42 DEPOIMENTO 1

When the patient ended all the treatment, and being still a teenager, he left the following testament:

My dentist referred me to the orthodontist because I had a crooked canine. So, after a panoramic radiograph she suspected that I could have a TMJ problem. Then she referred me to Porto Alegre to do a MRI, and from that exam it was found something that indicated a TMJ problem. So then I started the tratment with Dr. Lidia Yavich, that also investigated the tinnitus and my hearing problem.

When I was little I felt and hit the chin but my parents didn’t know that it could affect my TMJ.

I suffered a lot from an earache and sore throat. I had even scheduled an ear surgery but after six months of treatment it was no longer necessary to do it. Today I am doing well. I have a good hearing and I don’t have any more the tinnitus and the throat pain. I am happy with this treatment, thanks to God and to Dra. Lidia Yavich.

42 DEPOIMENTO

Here follows the testimony of the same patient seven years after the completion of the treatment:

Today, more than seven years after the end of the TMJ treatment with Dr. Lidia, and thanks to the God-given gifts to her, I haven’t been suffering any more with the earaches nor with the throat pain or the hearing loss. I had had, before the treatment, the indication to make an ear operation since I was loosing my hearing and that was not necessary with the TMJ treatment because during the treatment I was monitorated by exams that had proven that my hearing improved. Today I live a normal life, without having problems with those things from the past. I thanks the treatment done by Dr. Lidia which has healed me and improved my life.

I often observe the debate on etiology and therapeutics, especially in TMJ dysfunction discussions groups, which are integrated by patients and professionals. These groups are active not only in Brazil but in several countries and communities from around the world.

I hope this space will add, strengthen or clarify those discussions.

The professional who treats patients with TMJ pathology has to take into account, at the moment of studying the clinical case, the patient’s particularities and the anatomical structures that are involved and provoking pain and affliction to our patient.

Even if the professional is scrupulous, evolutions can be different from patient to patient. That is why the professional has to investigate carefully which are the structures that can improve or even heal and which are the ones that cannot improve or still which ones we do not know if can be improved in the process of treatment.

Recognizing what we do not know is perhaps more important than recognizing  what we do know: and the communication of this understanding to the patient is essential.

When we start a treatment we must be certain of the structures we can meliorate, or even prevent of getting worse  and we also must know which structures  we DO NOT HAVE THE CONDITION TO MELIORATE and we certainly must communicate that to the patient. Within this framework, the most important thing is to investigate if  we can improve the quality of life of the patient.

The masticatory muscles of the patient were electronically deprogrammed and a DIO (intraoral device) was constructed in neurophysiological position. In other publications computerized kinesiographic methods were mentioned.

In occlusion most often the healthy or pathological condition of the inter-oclusal space is not objectively considered. In this case the pathological free space of the patient is almost 7, 4 mm

16A ortese inicial so frontal

With this data and ALWAYS WITH THE INFORMATION OF THE IMAGES OBTAINED WITH THE MRI, we built a DIO (intraoral device) to keep the three-dimensionally recorded position.

One year after the beginning of neurophysiological treatment, the patient had to interrupt the treatment to undergo a spine surgery.

The patient returned 10 months after the interval, recovered from the intervention. The patient was  then again documented to assess any changes that might have happened during the interruption and the spine surgery.

PATIENT’S ANALYSIS AT THIS STAGE OF THE TREATMENT.

Patient with degenerative processes not only in the temporomandibular  joints but also in the cervical spine and lumbar spine which led her to surgery.

Inability to recapture of the right TMJ disk. Whereby this was an objective that was not taken into account.

Remission of symptoms and improvement of  life quality.

Physiological mandibular posture, recovery of free space interocclusal through the DIO (Intraoral device).

In this particular case even WITHOUT DISC RECAPTURE (CONDITION THAT WAS EXPLAINED IN THE DIAGNOSIS)  the patient can pass into the second phase, always taking into account that we should protect the joint during the night and during physical activity.

Each case is unique and the decision to move to a second phase also needs an individualized study.

It was decided to begin the SECOND PHASE of treatment to remove the DIO (intraoral device), keeping the neurophysiological occlusion.

26 orto 1

For this we used a three-dimensional orthodontics, where the teeth are erupted in order to reach the new neurophysiological position.

27 orto 2

In the second phase, in this case the three-dimensional orthodontic the patient is monitored and electronically deprogrammed. The device is often  recalibrated or replaced, to maintain the position obtained in the first phase.

28 orto 3

In the second phase, in this case the three-dimensional orthodontic the patient is monitored and electronically deprogrammed. The device is often recalibrated or replaced, to maintain the position obtained in the first phase.

In this sequence the patient is still with the DIO (intraoral device)  in the mouth.

We must remember that this is a patient with degenerative processes and impossibility of recapture of the right TMJ disc, the left disk is so damaged that it does not fulfill its function.

The patient no longer has symptoms.

The final MRI shows no worsening of the situation and in the frontal slice it shows a better three-dimensional location of the mandibular condyle and cortical improvement.

Comparative records of mandibular rest position at the beginning of the treatment to build the DIO (intraoral device), and at the end of the second phase of the treatment (tridimensional orthodontics) to build a DIO (intraoral device) for night use.

Notice that in the beginning of the treatment the patient had a pathological interocclusal space of 7.4mm, and in the record at the end of the second phase for the nocturne DIO the patient has 3.3mm of free interocclusal space.

We have to take into account that  the free interocclusal space IS A THREE-DIMENSIONAL SPACE, AND WHEN WE HAVE STRUCTURAL DIFFERENCES IN THE JOINTS, THE SPACE IS NOT EQUAL ON THE RIGHT AND THE LEFT SIDE.

37 DEPOIMENTO

I had made several appointments with specialists, such as otorhinolaryngologist, dentists and maxilo-facial surgeons. However, all of them were without success and that is when I looked for Dr. Lidia to whom I reported the following symptoms.

I used to wake up every day with a lot of pain on the left side, both in the head and neck and I used to feel a rigidity on the neck and shoulder. In that time I used to take painkillers every single day in the morning. I also used to suffer of a serious problem of bruxism and because of that I wore out my front teeth, both the upper and lower teeth, and I had to restore them. I used to feel a lot of pain from the tremendous pressure that I used to make between the lower and upper part of my mouth. Another symptom was the high sensitivity on the teeth when I drank cold liquids. I felt as my ears were always blocked in such a way that my hearing decreased. I also used to hear a noise, especially on the left side, which sounded like a continuous whistle.

38 DEPOIMENTO

I also told the doctor that when I was a child I was hit with a brick, in the middle of a child’s play.

After reporting all that she asked me to make many exams and many of them were made in the MY Clinic and finally she told me that I had a problem in the TMJ. I started a treatment with her in 2011. I started to use an acrylic splint on my lower teeth day and night, all the time, taking it of only for its hygiene.

The pain that I used to feel so much decreased and in short time I did not feel it any more. Doctor Lidia had to adjust the orthotic monthly, making exams in her clinic until it reached the optimal height. On the next year from when I started the treatment I had to interrupt it for 8 or 10 months because I had to make a column surgery but I returned to the treatment as soon as I was well enough. I kept on treatment for one more year and after that I started the second part of the treatment with braces.

39 DEPOIMENTO

At the time that the treatment ended I did not need to use any more braces nor the full time orthotic. Today I need to use the orthotic only when I do physical activities and to sleep. I never again felt the horrible pain that I used to feel. I also never felt again the sensation of having blocked ears and happily the noise reduced. Today I am very happy that I do not have to take daily painkillers and that I do not have any pain. I am very grateful to doctor Lidia because she discovered and solved my problem.

Reestablishment of the Bone Marrow Signal in a case of Avascular Necrosis of the Mandibular Head. Monitoring two years after treatment.

Preparing a new publication of the TMJ (temporomandibular joint) study and investigation page, I received the new MRI (magnetic resonance imaging) that I requested for the patient presented in the last clinical case published.

I decided that it was high priority to publish this follow up before the next clinical case.

Recapitulating the clinical situation and the images of the patient after treatment:

The patient had remission of symptoms.

The patient had improved function and recovered the vertical dimension.

The patient had improved aesthetics (recovering the vertical dimension).

The patient had recovered the mouth opening, without presenting limitation as observed before treatment.

The patient had improved her posture.

Is important to highlight that in this case, with discs of reduced dimensions lying anteriorly displaced WITHOUT REDUCTION when the mouth opened, the goal was to decompress, to recover the vertical dimension, and to wait for the medullary signal recovery by decompression, remembering that all bacteriological and rheumatologic research was negative.

At the end of treatment the MRI (magnetic resonance imaging) of the patient showed a MEDULAR SIGNAL IMPROVEMENT, yet still far from satisfactory recovery in terms of image, EVEN TAKING INTO ACCOUNT the improvement of symptomatology.

I will post some of the most remarkable initial MRI images before the treatment, to review the clinical case in detail enter in this link.

This publication will emphasis the images, a fundamental tool for understanding what we really can achieve beyond the patient’s clinical improvement.

Understanding the positive or negative changes in the structures affected in TMJ pathologies is critical in the comprehension of the etiology that led to the deterioration of the patient’s structures and consequently triggered the symptoms that affected the quality of life of our patients.

REMEMBERING THAT THIS IMPLIES A DIFFERENTIAL AND UNIQUE DIAGNOSIS FOR EACH CASE.

CORTE FRONTAL DA ATM ESQ INICIAL ANTES DO TRATAMENTO 2

MRI, frontal section of the left TMJ, closed mouth.

CAN BE SEEN AN IMPORTANT HIPOSSINAL COMPATIBLE WITH AVASCULAR NECROSIS.

Avascular necrosis occurs when blood flow to a bone is interrupted or reduced. It can be caused by various conditions, such as bone or joint damage, PRESSURE INSIDE THE BONE and other medical conditions.

The condyle affected by avascular necrosis has low signal on T1-weighted images as a result of edematous changes in trabecular bone.

Osteonecrosis of the condylar head corresponds to the death of bone tissue, also called avascular necrosis.

 Alteration in the bone marrow of the mandibular condyle is a possible source of TMJ pain.

FINAL 1

All relevant images were posted, nevertheless I think it is important to highlight THIS FRONTAL RIGHT TMJ comparative image because of the MEDULLARY SIGNAL OBVIOUSNESS.

The first image before treatment and the second two years of follow-up after treatment. MEDULLARY BONE WITH AVASCULAR NECROSIS RECOVERED IN A HEALTHY MEDULLARY SIGNAL.

Avascular necrosis occurs when blood flow to a bone is interrupted or reduced. It can be caused by various conditions, such as bone or joint damage, PRESSURE INSIDE THE BONE and other medical conditions.

The differential diagnosis of the alteration in signal intensity of the mandibular condyle begins with the knowledge of the normal characteristics of medullary signal.

FINAL menor

Right and left TMJ sagittal and frontal comparative slices. Before treatment and two years of follow-up after neurophysiological treatment.

finale finale

To  remember and follow in detail all the images and description of the case report, the reader should return to the previous post.

In the previous publication the control images after two years of treatment were NOT posted.

With the application of advanced diagnostic techniques like MRI the alterations of the medullary signal from the mandibular condyle can be detected, similar to those seen in the femoral head with osteonecrosis.

The detection of effusion and bone marrow alterations is important information before the treatment.

 The information of what really we achieve after our treatments in the image beyond the clinical improvement of our patient is also substantial information.

In this case showing the improvement and recuperation of the medullar signal with the correct mandibular reposition and decompression.

Temporomandibular Joint Pathology in a Patient with Congenital Fusion of two Cervical Vertebrae. First and Second Phase. Case Report.

When two adjacent vertebrae are fused since birth, the whole vertebral unit is called congenital vertebral block.

Embryologically this fusion is the result of an error in the normal process of segmentation of somites (segmented structure, formed on both sides of the neural tube) during the differentiation in fetal weeks.

Due to the existence of a mobile segment, free joints  (non-fused), on top and underneath the vertebral block, suffer more stress.

They may also produce an abnormal curvature of the spine.

Understanding the complex inter relation of craniomandibular disorders require a wide comprehension, not only on anatomy and physiology of head and neck, but also of the vertebral spine.

The cervical spine is the flexible link between the head and the trunk.

1 FOTO FRENTEMale patient arrived to the clinic for consultation referring headache, pain behind the eyes mostly on the right side and pain on the right eyebrow.

States that, when he passes his fingertips on the left eyebrow toward the right side, reaching the center he feels pain.

The patient reports that he tightens the teeth all day, and also mentions nocturnal bruxism.

He also complaints of pain in the back of the neck and pain in the cervical spine.

In his clinical history he reported a car accident when he was 12 year old.

He also had a strong blow in his mouth and mandible. He underwent a surgery on  L3, L4 and L5 because of disk herniation.

MRI TI: Frontal slice  of the right and left TMJ, closed mouth.

10 AB E FECHInitial kinesiographic record: significant loss of speed when the patient opens and closes his mouth. There is no coincidence between the opening and closing trajectories in the sagittal view record. The record  in the sagittal view looks very vertical when the patient opens and closes the mouth, which is  typical of deep overbites.

11 REGISTRO DE MORDIDATo properly evaluate the maxillomandibular relationship we  should start considering the physiological mandibular rest position.

Physiological rest is a concept, applicable to the rest of the body muscles.

The stomathognatic muscles are not the exception.

The masticatory muscles of the patient were  electronically deprogrammed and a new neurophysiological rest position was recorded.

The record showed a pathological free space of 11,8 mm and a retrusion of 2 mm.

Remember that the angulation of the mandibular condyle caused by trauma in early childhood led to a loss in the  vertical growth and a compression at the  level of the flexioned angle of the mandibular condyle neck.

   Click here To read more about traumatisms in childhood and the greenstick fractures of the mandibular process.

12 DENTES ORTESE

With the recorded data after the electronical mandibular deprogramming and the kinesiographic trace obtained with the jaw tracker, we constructed a  DIO (intraoral device), to mantain the tridimentional registered position.

This intraoral device must be tested to objectively measure the patient.

13 CONTROLE ORTESEKinesiographic record control of the DIO  (intra oral device), constructed in neurophysiological position. Neuromuscular trajectories  are coincident and the  interocclusal free space is now 2.4mm.

These controls must be performed PERIODICALLY DURING THE FIRST PHASE OF TREATMENT and also during the SECOND PHASE OF TREATMENT.
In the clinical cases published in the  TMJ STUDY AND INVESTIGATION PAGE  I post a minimum selection of the sequenced records obtained during the treatment.

It is important to remember that during the neurophysiological treatment the patient is measured and controlled during all treatment.

9A 1 RNM

The patient presented problems in the three-dimensional localization of the mandibular condyle

Even that structurally the mandibular condyles had undergone changes in the growth axis due to trauma in early childhood, they did not presented lesions that prevented us (after the  improvement of the three-dimensional jaw location) to continue with the SECOND PHASE OF THE TREATMENT.

9A 2 RNM

In this specific clinical case I decided NOT  to request a second MRI, since I didn’t need to control the improvement of the condyle disc complex nor the bone marrow signal.

The patient had remission of symptoms, allowing us to move on to the SECOND STAGE OF THE NEUROPHYSIOLOGICAL TREATMENT.

32  INICIAL DEPOIMENTO inglesSome time ago, while searching for an orthodontic treatment for my first child, I got to know Clinica MY.

At that time my priority was in fact to search for a solution to correct a teeth problem that my son had. After some consultations at the clinic I met Dr. Lidia, which already in our firsts and brief talks, and because of some complaints that I shared with her, she diagnosed that I, much more than my son, had problems related to dysfunctions in the TMJ.

She told me that I needed to search for a treatment.

In that occasion I had many teeth problems as inferior and superior teeth wear, broken tips, crackling when chewing.

32  FINAL DEPOIMENTO ingles

I had a lot of headaches, pain at the nape base and behind the eyes, and also pain on the back and shoulders. I also felt a pain sensation on my right eyebrow whenever I pass my hand on the forehead. It was something really strange and uncomfortable.

Happily this is something in the past. Thanks to the accurate diagnosis of Dr. Lidia and to the treatment that I followed strictly to the letter I am today free of those terrible symptoms.

I also would like to thank the careful work of Dr. Luis Daniel during all the treatment process and the attention and care that was given to me by all the Clinica MY team.

TMJ Study and Investigation Page. One year of publication

Dear friends,

At December 2014 I started the Project TMJ Study and Investigation Page. At first, all its content was offered in three languages: Portuguese, English and Spanish. Due to the analysis of the webpage access statistics, at March 2015 I decided to offer the content solely in Portuguese and English.

Nowadays, the medicine based on evidence is hierarchically stratified from top to bottom where in the base of the pyramid we find the clinic cases, which are rarely seen as evidence. The TMJ Study and Investigation Page had, in its conception, the purpose of posting the clinic cases, which were carefully published with the documentation related to each of the patients treated at Clínica MY with pain complaints, dysfunction and TMJ pathology.

INITIAL

The proposition was of presenting these clinic cases and concepts in order share them, offering free access to the content along images, surface electromyographies, computerized kinesiography, scanned before and after the therapeutic process. Cases of tridimentional orthodontics and neurophisiologic reabilitation of the second phase of treatment, after the TMJ treatment, were also included.

site em portugues nova ingles

The TMJ Study and Investigation Page is completing, in this month of December, one year since it started, and I want to celebrate its anniversary with you. With this project, we have a place in the Internet that presents a line of work known as neurophysiologic dentistry, which takes into account the whole body system. It is an area that also operates regarding the posture and the mandibular functioning. In order to do that, the physiologic dentistry aims to establish, in the patient, a position that is based on a harmonious relation between the muscles, the teeth, and the temporolandibular joints.

site em ingles novaIn the publication of the end of this year I have chosen the most significant images of the whole year of publications, with their direct links to each one of the originals publications.

The Tridimensional Neurophysiological Position of the Mandible in Implant Prosthesis Protocol

Nowadays dentistry has new resources for prosthetic resolution of patients with extensive loss of their dental pieces.

New technologies allow protocols to build prostheses where before, they would have no support solution.

Out of aesthetic recovery, essential for the patient IT IS NECESSARY to have an initial point of mandibular rest position, as these complex cases make rehabilitation more challenging.

1 frontal INICIALMale patient 54 years of age arrived to the clinic for consultation referring pain and sensation of plugged ear, especially on the left side. Also refers pain on top of the head and pain in the left shoulder.

2 PERFIL INICIALThe patient reports stiffness and pain in the back of the neck, a different sensation on the left side of the head as tingling and loss of sensibility and “blocked ear”

Refers an uncomfortable sensation in the left eye, in his words says that “the eye is sensitive”.

Refers hand tremor.

3 protese inicialThe image of the patient’s habitual occlusion shows a Class III or mandibular prognathism.

The  patient reports the prognathism  condition even before the dental loss.

When we study occlusion most of the time we do not consider if the inter-occlusal space is healthy or pathologic.

4 oclusaisPatient’s superior and inferior oclusal view.

4A questionarioWhat most encourages the patient to seek treatment was the sensation of blocked ear and his desire to resolve the issue.

The patient also relates noises when chewing and fatigue of the masticatory muscles. The patient also reported a numbness sensation near the left ear.

The patient had been medicated by another professional with muscle relaxant, but he did not feel any symptoms change.

5 PANORAMICA INICIALPatient’s initial panoramic radiograph before neurophysiological  treatment.

The patient has this protocol for more than 18 years.

The patient reported a periimplantitis history, and had no image prior to implant placement.

6 LAMINOGRAFIA INICIALPatient’s TMJ right and left laminography, closed and open mouth before neurophysiological  treatment.

7 TELERRADIOG INICIALPatient’s lateral radiograph in habitual occlusion before treatment.  Marked prognathic profile.

7A TELERRADIOG INICIAL LINHAMarking the aesthetic plane of  Ricketts in the lateral radiograph with the profile of the patient.

8 FRONTAL INICIALPatient’s frontal radiograph before treatment.

9 ELETROMIOGRAFIA INICIALPatient’s dynamic electromyography record in habitual occlusion before treatment.

In this dynamic record we registered the anterior right and left temporal muscles, the right and left masseter muscles, the right and left digastric muscles and the right and left upper trapezius muscles.

The right masseter muscle ALMOST CAN NOT RECRUIT MOTOR UNITS during maximum sustained  intercuspation, it can only generate 21 microvolts in the selected band.

Important asymmetry between the two masseter muscles, right and left.

10 ABERTURA E FECH INICIALPatient’s initial kinesiographic record: we can see a good speed when the mouth opens and a reduction of speed when the mouth closes.

There is no coincidence between the opening and closing trajectories in the sagittal view.

The opening movement has a propulsive closing and a lateralization in the frontal plane to the right of 8.2 mm.

11 CICLOS MASTIGATORIOS HABITUAL ANTES DO TRATThe patient’s masticatory cycles are registered with a jaw tracker. In the record of the masticatory cycles we used almonds to register chewing activity.

This post will not make a detailed analysis of this record. But it is important to note that: on the left side of the graph, even if the patient is chewing almonds on the left, THE GRAPHIC APPEARS ON THE RIGHT SIDE. This is due to mandibular torque that the patient needs to perform to chew.

11ARNMMRI: left and right TMJ closed mouth.  I chose this slice to show important asymmetry between the right and left side.

The left side shows a posterior dislocation of the articular disc. There is NO ARTICULAR DISC on the right side, is IMPORTANT TO MARK THIS, since in several posts I emphasized the importance of recapturing the disks when possible, (IN THIS CASE I CAN NOT RECAPTURE A STRUCTURE THAT DOES NOT EXIST).

In this particular case the request of resonance is part of the protocol to obtain fundamental information in the formulation of diagnosis.

Different slice and parameters do not show bone edema or other information requiring different interventions within the treatment.

The goal in this particularly case  will be the three-dimensional repositioning of the jaw, TO RECOVER the neurophysiological function, which should be widely understood, so that the muscles, temporomandibular joints and teeth and prostheses could work in balance.

12 JAW TRACKER BIOPACKTo determine the neurophysiological three-dimensional position of the jaw, even in cases of extensive rehabilitations we have to consider the physiological position of the mandibular rest.

The masticatory muscles of the patient were deprogrammed electronically and a resting neurophysiological position was recorded.

The patient has a PATHOLOGICAL FREE WAY SPACE OF 7.2 mm. Maintaining the physiological 2 mm we still have more than five mm discrepancy, to be recovered tridimensionally.

The jaw also presents a retro position of almost two mm and a deflection at closing of 0.5 to the left side.

13 DENTES COM ORTESEWith this data and ALWAYS WITH THE IMAGES INFORMATION, we constructed a DIO (intraoral device) to keep the three-dimensionally recorded position.

This device must be tested electromyographically to objectively measure the patient.

13BTELERRADIOG COM DIOPatient’s lateral radiograph with the DIO in neurophysiological position.

13CTELERRADIOG COM DIO LINHAMarking the aesthetic plane of  Ricketts in the lateral radiograph with the DIO in neurophysiological position.

The DIO is an orthopedic device, recorded and controlled electromyographically. The DIO (intraoral device) is used to support, align and ameliorate deformities in order to improve the functions of the jaw, temporomandibular joints and the muscles.

14 ELETROMIOGRAFIAS COM o DIOPatient SEMG record with the DIO (intraoral device) in neurophysiological position built above the patient’s prosthesis.

We can note the improvement of the right masseter muscle activity. Before the treatment the right masseter muscle could not recruit motor units.

15 ELETROMIOGRAFIAS COMPARATIVASComparison of the SEMG records: before the treatment in habitual occlusion and with the DIO (intraoral device) in neurophysiological position built above the patient’s denture.

WE MUST CONSIDER that years of muscle accommodation and the central nervous system engrams cannot be modified with a first orthotic or DIO

That’s why the DIO should be adapted, changed, and recalibrated to follow dimensional changes that will happen when muscles are aligned.

16 ABERTURA E FECH COM O DIOPatient’s kinesiographic record after neurophysiological treatment.

Significant improvement in the opening and closing trajectories.

The closure no longer has a propulsive trajectory.

The lateralization which was 8.2 mm was reduced to 2 mm.

27 Patient testimonyI lived for a long time with discomfort that sometimes manifested itself by a feeling of numbness and sometimes by headaches.

I could not identify the cause; although I repeatedly searched for expert help.

On the recommendation of my sister and my sister in law who were being treated by Dr. Lidia I consulted her and started a treatment which lasted a long period, getting excellent results and today I feel good without the symptoms that hindered me so much.

I appreciate the commitment and dedication of Dr. Lidia and her team.

Patient with Ankylosing Spondylitis and non inflammatory TMJ pathology

Female patient, 40 years old comes to consultation referred by her rheumatologist WITH STRONG PAIN IN the TMJ (temporomandibular joint), TWINGES IN THE HEAD AND MOUTH OPENING LIMITATION.

The patient had a diagnosis of seronegative spondyloarthropathy until then nonspecific.Later diagnosed as Ankylosing Spondylitis

Seronegative spondyloarthropathies refers to a group of diseases that share common characteristics, including the occurrence of inflammation in the spine, peripheral joints and in various peri-articular tissues, in particular entheses.

Seronegative spondyloarthropathies laboratory outstanding feature is the absence of rheumatoid factor and auto antibodies. They have strong association with human leukocyte antigen HLA-B27.

1  The patient reports clicking on the right TMJ, difficulty to open the mouth, difficulty and paint in chewing. She also reports bruxism.2She reports feeling headache, neck pain, pain in the right eyebrow, pain behind the eyes, pain in the right shoulder. She also reports pain in both temporomandibular joints which is stronger  in the right joint.

Points where the patient reports pain

The patient marks on the record the most important points of pain.3  In the first consultation, during the anamnesis the patient reported that she had initiated a treatment for the bruxism problem, and that at one point with the device change she  began to feel a very strong pain and her mouth locked.

4The occlusal view shows the superior anterior sector wear and the anterior lower sector wear.5Patient’s panoramic radiograph.6The joints radiographic image shows the superior and posterior positioning of the articular process on the left side in the joint cavity when the jaw is in maximal intercuspal position.

In the maximum opening position, there is flattening of the posterior and anterior surface of the left mandibular condyle process and a flattening of the superior and anterior surface of the right mandibular condyle process. The right side also presents an alteration of the growth axis of the mandibular condyle.

6BPatient’s lateral and profile radiograph before treatment.7Patient’s lateral radiograph and cervical spine before treatment.7BPatient’s frontal radiograph in habitual occlusion before treatment.8 abre e fecha inicOpening and closing computerized kinesiographic record, the patient can open only 32 mm feeling strong pain, which shows an important limitation.

The patient also has a deflection of 2.7 mm to the right.8 B COMP abre e fecha inic Note in the skull graph, the left condyle moves more than the right condyle where the deviation is.

9The surface electromyography exam evaluates the superior anterior temporal right and left, the right and left masseter, the right and left digastrics and the right and left upper trapezius.

In this electromyography record the patient could not generate a good activity when we asked to bite hard (keeping the teeth in maximum intercuspation) and clench.

At the beginning of the record when we asked the patient to open the mouth it is important to note the different activity between right and left digastrics.

The left digastric activates double than the right digastric.

9

Image enlargement showing the difference in translation of the mandibular condyles. Patient in maximum mouth opening.

It is important to be able to understand and connect all the information, the surface electromyography and the computerized kinesiograph. These data still does NOT PROVIDE A DIAGNOSIS, However they are tools to help us in the diagnosis.

I asked the patient for an MRI-(magnetic resonance imaging) of the temporomandibular joints.

When the patient filled out the clinical record for the MRI she reported that she did a tattoo a month before, that prevented the realization of the MRI until completing the time of three months after the realization of the tattoo.

Remember that the resonator is a large magnet and tattoos have pigments which may contain metal and could heat up and cause burns.

We kept the patient with a temporary splint until we had the MRI information, as explained in previous posts; WE MUST NOT TREAT A PATIENT WITHOUT  A DEFINED DIAGNOSIS.

We could easily assume that as the patient had a systemic nonspecific inflammatory arthritis attacking various joints of her body also the TMJ could be involved.

It is fundamental to rethink something which SOMETIMES could be ONLY A CONJECTURE, even if the patient is a carrier of an inflammatory autoimmune disease.

In the systemic part it is the rheumatologist who will decide the therapy.

Our part is to promote a non-compressive position of the TMJ where the masticatory muscles may perform without loading the joint, and where the patient can fulfill all the functions of the stomatognathic system.

9APatient’s inflamed elbow after synovectomy with the disease still not controlled

9A  MRI: sagittal sections selected. Left TMJ closed mouth: articular disc anteriorly displaced. Change in the growth axis of the mandibular condyle.

Left TMJ open mouth: limitation in mouth opening.

The images here are in T1, all images analyzed including T2 and STIR DOES NOT SHOW inflammatory signs.

It is relevant to remember that in the first consultation, during the anamnesis the patient reported that she had initiated a treatment for the bruxism problem, and that at one point with the device change she began to feel a very strong pain and the mouth locked.

The patient remembers that the device change aimed to align the median line of the upper incisors to the median line of the lower incisors.

This has to be a warning to all of us in dentistry which were taught to carry out all our treatments without knowing the condition of the TMJ.  

9B  MRI: sagittal sections selected. Right TMJ closed mouth: articular disc anteriorly displaced. Change in the growth axis of the mandibular condyle.

Right TMJ open mouth: limitation in mouth opening.

After conducting the analysis of the MRI images, studying all the slices and all required parameters (not included in the post), we can proceed to carry out a neurophysiologic record.
10The masticatory muscles of the patient were electronically deprogrammed and the rest position was recorded with a computerized kinesiograph.

This record has been difficult to achieve. The patient was limited and in great pain. A very low DIO was made, leaving an interocclusal free space of one mm which would normally be too little.

When I was 39 years old I was diagnosed by my rheumatologist with arthritis.

All major joints of my left side were suddenly and without warning, very swollen, such as knee and elbow, preventing me from performing my simplier movements such as standing and stretching my arm.

I had swelling, redness and intense pain. Then I started to feel pain in the TMJ. I ended up in the clinic of an orthodontist and facial orthopedist  who told me that I had ‘bruxism’ and that I needed to use a device to place the tongue in the right position.

I wore the appliance for a month or two, my TMJ locked, I could not open my mouth and I felt an absurd pain in my entire head, I no longer knew what hurted more, if it were the joints of the body or my head and mouth.

My rheumatologist, apprehensive that I could have arthritis also in the TMJ immediately referred me to Dr. Lidia Yavich, who received me in the office and managed to relieve my pain completely .

I HAVE TO STRESS THAT, THERE WAS NO MEDICATION THAT COULD CEASE THE PAIN that I felt in the TMJ and in the cervical spine, NOTHING!

After the imaging studies performed by indication of Dr. Lidia, we came to the conclusion that I was not suffering from arthritis in both TMJ, but from a dislocation  of my right condyle  after using for a short time a mistaken device to place my bite and tongue in the ” RIGHT POSITION”

That treatment did not considered important assumptions as the asymmetry of my condyles, or their position, or the disc status in relation to the condyles, causing much suffering.

It took me a long time to understand what was happening to me in my TMJ; I suffered from absurd pain in the head in the middle of a very difficult treatment for arthritis. I was disfigured, terrified and unsure after using the first device with the previous professional because he did not know how to end the pain and even seemed, not to know what was actually happening with me.

I had panic to imagine that I had arthritis in my TMJ, but only after the MRI and the Dr. Lidia interpretation it was possible to exclude the possibility of rheumatic disease in the TMJ in that moment, and from then on to make an efficient treatment.

In a few weeks Dr. Lidia not only took out ALL THE PAIN of the TMJ, but also led me to a treatment that repositioned my disc and  stopped the pain, even being a carrier of a severe autoimmune disease.

I have been using the DIO for seven years without any pain, I have full understanding of the meaning of bruxism in my case and correct approach to the problem, including the options that I could have for a more permanent solution instead the use of the DIO.

I am very grateful to my rheumatologist  today for indicating me a treatment that saved me, because I certainly would have gone crazy with those TMJ pains.

I am very grateful to Dr. Lidia who took me from the rock bottom in which I found myself, ignorant from all  that was happening in a joint so unknown from most of us:.the TMJ.

Tridimensional Orthodontics in the Second Phase of TMJ Pathologies

1A

In the former publications of this study page some of the neurophysiological fundaments of the TMJ pathologies treatment were presented, the importance of the differential diagnosis and also the utilization of bioinstrumentation like surface electromyography and jaw tracker were also introduced.

Patients images relating their symptomatology were also shown, some of the diverse etiological factors as traumatisms in infancy, especially green stick fracture, intra articular discs recapture in reducible dislocations, interrelation between Craniomandibular disorders and vertebral spine, as well as a case of cervical dystonia and its relation with TMJ that can also be read in this page. From December 2014 there were seven publications.

1

When we talk about TMJ pathologies treatment we need to understand that there are different approaches. The proposal of a Palliative treatment is the Symptomatic treatment, which tries to block the symptoms. For that means, it uses analgesics administration, anti- inflammatory drugs and muscle relaxants.

The restorative approach is the treatment that aims, when possible to correct or to heal what is damaged. Recognition of what is wrong (differential diagnosis) must precede the question of how to fix it. To know what is wrong, it is necessary a differential diagnosis. This diagnosis must always be elaborated before we reach a treatment proposal.

2

When our proposal is a restorative treatment, we have a FIRST PHASE where the objective is to heal the joint when it is possible. Sometimes we can only improve the joint condition or to avoid its deterioration.

To know what we can treat and what we cannot deal with, and the limitations of every individual case.

3

When we finished the first phase, we compare if the control images of the case corresponds with the goals we intended to achieve in our initial diagnosis. We know that there are cases that can meliorate, others that we can avoid its aggravation, and still others that we can only can relieve the pain. If the case has positive results of the first phase we can initiate a second phase of the treatment in order to remove the device that is used in a permanent way during the first phase of the treatment.

For this we can perform a tridimensional orthodontics, a neurophysiological rehabilitation or the combination of both.

Always remember of keeping the mandibular localization in equilibrium with the muscular planes, temporomandibular joint and dental planes.

4

I will relate what happened at the current week with a teenager patient that had finished the first phase, in a case of  neurophysiologic decompression of the temporomandibular joint and where she was still wearing the DIO (intraoral device)

The patient had remission of her symptomatology (ear pain irradiated from the TMJ since childhood), and now she was preparing herself  to initiate the second phase with a tridimensional orthodontics. I wasn´t satisfied with her breathing so again I asked for an evaluation to meliorate her breathing and consequently her tongue position.

The professional that made this evaluation affirmed that the patient presented an open bite and that she needed to consult a buco maxillary surgeon to “close her bite” by surgery.

The anguish that was provoked on the patient and that consequently also affected me, resulted in my indignation on her conclusive opinion referring the patient to a surgical consultation without firs entering first in contact with the professional responsible for the treatment (me in this case)

In any way I demand complicity of any professional, since I consider ethics beyond everything. As much as respect for the patient.

This event encouraged me to publish a case on tridimentional orthodontics in the second phase of TMJ pathologies

Before the SECOND PHASE, let´s begin with the FIRST PHASE.

5

Female patient, 17 years old consults in the clinic complaining of headache, ear pain, shoulder pain and bilateral clicks.

In the clinical inspection she had strong ache when retrodiscal palpation was performed.

The patient showed an “ideal occlusion” and in the clinical tests she did not exhibits any kind of interferences neither in protrusion nor in lateral translation.

6

Patient’s initial laminography in habitual occlusion before treatment

Patient’s initial laminography in habitual occlusion,  retro position of the mandibular heads, especially on the left side provoking an important retrodiscal compression.

7

Patient’s MRI in habitual occlusion, both anterior reducible disc luxation, retro- position of the mandible heads and modification of the growth axis provoked by a traumatism in infancy (Structural modification of the mandibular condylar process as one of the sequels of traumatism in infancy). The luxation is reducible (MRI in open mouth not included in this post)

8

Patient’s initial electromyography record (4 channels) in habitual occlusion

In this record we measure both right and left anterior temporalis, and right and left masseters. Notice that the masseters that are the most potent muscles of the masticatory system cannot generate activity.

9 10

A static image doesn’t speak of muscular harmony, doesn’t show if there is coordination between the systems and does not show if the patient has local or distant pain.

11

Patient’s masticatory muscles were electronically deprogrammed. A bite was registered in a neurophysiological position with a jaw tracker.

The patient presents a pathological free way space of 6,2 mm and a retro mandibular position of 2,5 mm.

12

With this data we construct an intraoral device (DIO) tested electromiographically to support the neurophysiological occlusion.

13

Patient’s comparative laminographies

Patient’s initial laminography in habitual occlusion, retro position of the mandibular heads, especially on the left side provoking an important retrodiscal compression. The new laminography with the intraoral device in neurophysiological position shows the tridimensional decompression of the retrodiscal zone.

Comparison of one of the slices of the MRI. Right closed TMJ before the treatment in habitual occlusion and in a neurophysiological occlusion with the DIO.

Disc in physiological position and tridimensional decompression of the mandibular head.

Correlation with the electromyography records in habitual occlusion and in neurophysiological occlusion with the DIO.

17

Lateral radiograph of the patient for the initiation of the tridimensional orthodontics treatment. The patient is with the DIO (intraoral device constructed in neurophysiological position)

Patient’s masticatory muscles were electronically deprogrammed for the bite registration and the construction of the intraoral device.

Not all case can pass to a second phase, orthodontics, prosthodontics or rehabilitation.

There are patients with active autoimmune disease, where is not possible to eliminate de intraoral device, because these patient’s  anatomical structures ( temporomandibular joints, cervical spine…) are affected by the disease, what makes this structures unstable pillars, because of the active inflammatory process.

Starting the 2 phase of the treatment in this case with a tridimensional orthodontics. The device will be removed keeping the muscular planes in equilibrium with the osseous and dental plans.  INITIATING THE ACTIVE ERUPTION.

21

Image with and WITHOUT the intraoral device. The space between arches IS THE SPACE THAT WE NEED TO RESTORE (this space is filled with the DIO). The DIO operated as a tridimensional boot sole. IN THE SECOND PHASE THE ACTIVE ERUPTION OF THE TEETH will fulfill the objective

22

Continuing the treatment in the tridimensional orthodontics. Image with and without the device. Posterior sector already erupted.

23

Molar and pre-molar sector already erupted. Alignment of the lower incisors and finalization of the tridimensional orthodontics in the second phase of TMJ Pathologies.

The ultimate goal in an orthodontic treatment is to treat all three components of the stomatognathic system and create an environment for synergistic function of the teeth, temporomandibular joints and neuromuscular system.

24

A tridimensional orthodontic needs to maintain the tridimensional position of the mandible in balance with its osseous and muscular planes obtained in the first phase, and whenever possible it needs to keep the temporomandibular joint in an harmonic relation with the mandibular fossa as well with the articular disc in correct position.

gRUMMONS

The patient’s clinical history, clinical inspection, technology, bioinstrumentation and images, helped us to improve TMJ pathologies diagnosis and treatment.

When we arrive to a SECOND PHASE, many professionals and patients don´t know that the active eruption has been used from MANY, MANY years ago. Dr. Duane Grummons book edited in 1994 is only one of the several examples. Logically a TRIDIMENSIONAL ORTHODONTICS in the patient with TMJ Pathology needs a differential diagnosis and a restorative treatment in the FIRST PHASE.

If we don´t understand that teeth are the ending point of a joint…

If we don´t understand that this joint can be affected by systemic

and local pathologies…

If we don´t understand that it is the muscles that move the mandible

and propitiate the rest position…

If we don´t understand that structural differences determine tridimentional adaptations…

We may not understand treatments failure, in the cases where the patients present TMJ pathologies.
