High technology in the diagnosis and treatment of TMJ pathologies and the optimized bite for enhance the highest performance in Sports Dentistry

0

The advances in biotechnology have allowed a deeper understanding of the pathologies that affect the temporomandibular joint.
Nuclear magnetic resonance images and biotechnology were transferred to the realm of clinicians, no longer being exclusive to the realm of researchers.
These advances play a key role in conjunction with clinical examination, carefully integrated with the patient’s history and pathophysiology.
Controlling pain is a fundamental goal, but it is also possible today, in certain cases, to regenerate structures.

Cephalometry  presupposes that the mandibular heads are in a physiological position and patients do not present any pathology in the temporomandibular joint.
Many of our patients looking for correction of a malocclusion, or a prosthetic rehabilitation, present noises in their TMJ, facets and erosions in their images and pain in the retrodiscal palpation.
Hard tissue injuries as a result of early childhood trauma can lead to injuries to the disc and ligaments.
Infections and autoimmune diseases should be considered, since they affect not only the temporomandibular joint but also all the fascial and muscular chains of the human body.
The evaluation of TMJ and the diagnosis of its pathologies should be an inseparable part of our procedures, not only in orthodontics and orthopedics but in all fields of dentistry.

In October 25 and 26 we will met in the beautiful city of Dijon where I will have the pleasure to share with you about TMJ pathologies and their impact on the whole body system and in sport dentistry.
• We will speak on images of the temporomandibular joint from the gold standard that is MRI, but also I want to mark the signs in everyday radiographs.
• We will also analyze posture and occlusion since dentistry is pure neurology and the interventions that we perform in our patients are present in the whole body. Degenerative processes that affect the head of the mandible, disk dislocations, changes in the growing axis of the condyle, impair the joints. The masticatory system represents the highest link of the postural chain and deeply influences the lower links. This relation is fundamental not only in pathology but also in sports dentistry.
• See you in Dijon.
À bientôt

Hello my friends from Europe: on the 25 and 26 of October I will be in Dijon, France at the High Tech Denta explaining and teaching how we can adjust, using the biometric tools, the mouth guards and splints that we construct to enhance the performance in Sports Dentistry. See in Dijon!

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.

MARCUS LAZARI frontal E SAGITAL

In the publication of this year’s end I have chosen the most significant images of all these years of publications, with direct links to each of the original publications.

At the end of this publication I placed the links of the publications of the first year of this page.

TMJ Pathology in Professional Musicians: A look beyond the risk factors. Physiological Neuromuscular Rehabilitation. First and second phase. Case Report.

Several articles and studies cite the prevalence of TMJ dysfunction in violinists and violists, especially by prolonged flexion of the head and shoulder, posture necessary to keep the violin in position. Studies also report that the incidence of TMJ dysfunction in musicians is similar to the general population.

Professional musicians require many hours of training and improvement that involve complicated movements, fast and repetitive actions with over use of the hands, fingers, arms and head.

Most articles report anxiety about professional performance and increased muscle tension, but few do a particular study of the state of the anatomical structures of the cases studied.

1 postura inicial frontalA 45-year-old female patient referred by her physiotherapist consults with complaints of headache, pain in the cervical and scapular region, muscular contractures in the mandible.

The patient also reports mandibular displacement when playing the violin and pain in both temporomandibular joints.

2 postura inicial lateralThe patient also reports clicks in both temporomandibular joints and occasionally the sensation of clogged ears.

Frequent pain in the spine and both shoulders.

At that time the patient had already consulted physiotherapists, rheumatologists, psychiatrists and psychologists.

In the report there is rectification of cervical lordosis.

Degenerative discopathy in C5-C6, observing reduction of the height of the disc space and osteophytic proliferations reactional. At this level the disc-osteophyte bar is identified that touches and distorts the ventral face of the dural sac.

There is no stenosis of the central vertebral canal.

Neural foramina with amplitude within the limits of normality.

Mild signs of uncovertebral arthrosis C5 and C6.

10 eletromiog dinamica inicialDynamic electromyographic record in patient’s habitual occlusion before treatment. Note the minimal activation of the right and left masseter muscles in maximal intercuspation and the high activation of the right and left temporal muscles.

The masseter muscles are the most powerful muscles of the stomatognathic system, the temporal muscles even being elevating muscles have to have an equal and preferably smaller activation than the masseter muscles.

11 cineciog 1Initial cineciographic record of the patient.

Three-dimensional view of the mandibular displacement.

The record shows mandible opening, closing and speed when the patient makes these movements. The patient shows a 47 mm opening and a right deflection of 3.9 mm

Primary objective has to be the three-dimensional decompression of the mandibular condyle.

21 FRONT DIR E ESQMRI: frontal slice of right and left temporomandibular joints, closed mouth in habitual occlusion before treatment.

The frontal slice of the right temporomandibular joint shows a loss of joint space, especially in the region of the external lateral pole of the joint. Both frontal images show a decrease in joint space.

Slight medial disc deviation.

21A registro inicial para o DIOTo correctly evaluate the maxillomandibular relationship we should begin to consider the physiological rest mandible position.

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 deprogrammed electronically and a new physiological neuromuscular position at rest was recorded.

The patient has a pathological free space of 5.8 mm, already discounting the two physiological mm of a healthy free space.

The patient also presented a 2.1 mm mandibular retroposition

22 oclussao com o DIOWith these data we constructed a DIO (intraoral device), to maintain the three-dimensional recorded position. This device must be electromyographically tested to objectively measure the patient.

It is logical that the report of the patient’s symptomatology is important, but the surface electromyography shows in an objective way if the muscular function improved, worsened or did not modify.

22A eletromiografia com o DIOElectromyographic record with DIO (intraoral device) in physiological neuromuscular position.

Note the higher recruitment of motor units in the masseter muscles that previously showed very little activity.

22A Registro cinesiográfico para controlar o DIO em posição neurofisiológicaCineciographic record for the DIO (intraoral device) control in physiological neuromuscular position as the device is changed or recalibrated.

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

Each case IS UNIQUE. There are cases where the TMJ structures are so damaged that the objectives outlined will have limitations dictated by the initial diagnosis.

These limitations refer not only to the structures of the temporomandibular joint, but also to the patient’s systemic condition.

Patient testimony:

What made me look for the treatment were recurrent headaches, frequent

(weekly) and intense, which lasted, on average, 2 days, affecting my productivity

at work as well as leisure hours.

The pain did not subside with common analgesics, requiring strong medication, which, in turn, only softened the pain a little.

Today, after the treatment, I can say that only very rarely do I suffer from these pains, greatly improving the quality of life, besides the posture.

TMJ Pathologies Treatment: Patient with headache for 30 years. Neuromuscular Physiological Rehabilitation. First and second phase. Case Report.

1 FOTOS FRENTE

A 54- year old female patient arrives to the clinic for consultation, referred by her rheumatologist with complaints of daily headache since her 23 years of age. The patient associates the beginning of the headache with the installation of a definitive crown on the right upper central incisor. When she was 12 years old the suffered a traumatism that provoked the fracture of the tooth. The patient also reports bruxism.

2 FOTOS PERFIL 2

The patient reports that in consultation with a neurologist, a nuclear magnetic resonance of the skull was requested, in which a change in white matter was detected.

At the same time the patient consults with a cardiologist. A FOP (Patent Oval Form) is detected, with no need for a surgical approach.

2A

After years and years of consultations and treatments for daily headaches, the patient also has a diagnosis of fibromyalgia.

The patient makes use of marevan, 5mg daily as indicated by the Cardiologist.

Sandomigran 1 time per day per Neurologist indication.

Nexium 40 mg once daily indication of Gastroenterologist.

Marevan works in the prevention of venous thromboembolism, systemic embolism in patients with prosthetic heart valves or atrial fibrillation, stroke, acute myocardial infarction and recurrence of myocardial infarction. Oral anticoagulants are also indicated in the prevention of systemic embolism in patients with cardiac valve disease.

Sandomigran, pizotifen is an antaminic characterized by its polyvalent inhibitory effect on biogenic amines, such as serotonin, histamine and tryptamine. It is suitable for the prophylactic treatment of migraine, reducing the frequency of seizures. Pizotifen also has appetite-stimulating properties and is mildly antidepressant.

Nexium: Expected action of medication, disappearance of symptoms of heartburn, epigastric pain and acid regurgitation. Healing of peptic ulcers.

The patient’s masticatory muscles were electronically deprogrammed and the mandible rest position was recorded with a computerized kinesiograph.

An intraoral device (DIO) was made to for three- dimensional mandible repositioning.

The patient presented a pathological free interocclusal space of 4,4 mm, a mandibular retroposition of 1, 6 mm, also a right deviation of 1 mm.

In this specific case: three-dimensional orthodontics together with the rehabilitation of the necessary dental pieces and aesthetic improvement of the patient’s anterior teeth.

25 PANORAMICA ANTES DA ORTO

At this point I had to make a decision regarding the permanence of the deciduous tooth, firm and without mobility.

I did not think I should extract it for the placement of the implant, but to maintain it.

I clarified to the patient that during orthodontics we could lose it. I understood that this would have a compromise in the patient’s occlusion, but this fact did not concerned me, with the TMJ being decompressed and the patient functioning well, both electromyographically and in the computerized kinesiograph tests.

45 DEPOIMENTO 1

At age 11, I had a fall and broke the upper incisor tooth. At the time, I sought a dentist and he said that I should wait for the adult stage to make the porcelain definitive crown.

In 1986, when I was 23, I went to another dentist to make the crown. After the root canal treatment, the crown was placed.

In that moment I felt that there was an elevation that touched the lower tooth. The next day I woke up with an endless headache. Day by day the pain intensified.

I returned to the dentist and reported the fact, he said that in time it would settle. For 25 years I investigated the reason for my headache with several doctors.

In 2006 a rheumatologist asked me for an MRI of the skull, changes were identified in the gray matter. During this period, I was admitted to HMV for an investigation, and the diagnosis was SAF, topiramate 50 mg was introduced as a preventive of migraine and anticoagulant.These drugs were used from 2006 to 2011.

45 DEPOIMENTO 2

In 2007, I underwent systemic chemotherapy with METOTREXATE for 1 year. In 2011 another pain site showed up, this time in the hip, so I underwent corticoid in the vein for 6 months.

I decided to abandon the treatment, because it was no use. I looked for a respected neurologist who switched all my medication for an anti-allergy for headache prevention and an antiplatelet.

The diagnosis was leukoencephalopathy in a small degree. I also gave up treatment, because it did not work, either.

This neurologist referred me to another rheumatologist who examined me and identified a problem in my TMJ and a bursitis in the hip.

The same rheumatologist sent me to Dr. Lidia Yavich and to an orthopedist. In a short time I did not feel the same headache when I woke up. After all this, I continue to do MRI, and the changes have stabilized.

45 DEPOIMENTO 3

 

I sought an opinion from a second neurologist, and he thinks that all the changes I have are due to the intensity of the headache that I felt daily.

He did not agree with any diagnosis made so far.

I also believe that, because after the treatment with Dr. Lidia, I regained my quality of life.

The medication I use today: antiplatelet due to the existing changes and because I have a patent foramen ovale.

I thanks also to Dr. Luis Daniel for the conjunct treatment restoring function and aesthetics.

 

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.

Relates pain in both shoulders.

1B FOTO FRENTE

The patient reports pain and clicking in both temporomandibular joints. He also complaints from a crepitation sensation in both TMJ.

He refers a sensation of blocked ears and bilateral tinnitus.

2 FOTO PERFIL

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.

3 DENTES Patient’s habitual occlusion image before the treatment in the consultation day.  We can notice the  fractured superior incisors   and the absence of the left superior canine.

4 OCLUSAL SUP E INFSuperior and lower oclusal view of the patient before treatment. In this image we can see the wear of the lower incisors and the fracture of the upper central incisors.

5 PANORAMICAPatient’s initial panoramic radiograph: we can observe the absence of the  18, 23, 28, 38 and 48 elements. We can also notice the maxillary sinus extension on the premolars and molars region.

6 p6Patient temporomandibular joint laminography before treatment: we can observe the superior and posterior position of the right condylar process in the articular cavity  and the lower posterior positioning of the left condylar process in the articular cavity when the jaw is in maximum intercuspidation position.

In the maximum open position, we can observe the anterior angulation of the articular processes. More significant on the left side. Flattening of  the posterior surface of the articular processes.

9A 1 RNM 1MRI TI: Sagittal slice sequence of the left TMJ closed mouth.

We can see that despite the anterior angulation of the articular process (because of one of the sequels of traumatism in infancy) the disc is positioned at the head of the mandibular condyle.  Notice that the health of the soft elements had been preserved, even so there is a compression of the retrodiscal elements at the level of the  neck flexioned angle  of the mandibular condyle.

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.

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.

15 sequencia 1In the upper image we can observe from top to bottom:

Habitual occlusion of the patient before treatment.

In this case we cannot change a congenital fusion of the cervical vertebrae, but if we understand that there are myofascial chains that connect the TMJ to the body, we may then improve the three-dimensional location of the mandible and help the system. Naturally, the system is a whole and depending on each clinical case we will need the help help of professionals of different specialties.

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.
