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.

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)

47 DEPOIMENTO 3

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.

46 DEPOIMENTO 1Patient testimony

Dear Lidia,

You know, I really realized how much the treatment I’ve undergone improved my quality of life when I was in the clinic this year (2018) and I looked at my file with the information I had recorded when I started treatment.

To be honest I did not even remember that before the treatment I had pains in the jaw joints !! And how strong they were.

I always had headaches and migraines, besides the pains in the joint of the mandible. I always record it because I remember when I was a child I already felt them. I felt very ill and indisposed when I had crises.

In a certain phase of my life due to the increase in the frequency of pain headache and the constant vomiting I went to many doctors because I thought I was with stomach problem. I thought my headaches and migraines were consequence.

47 DEPOIMENTO 2But based on the examinations I made at the time, my general practice told me that the question of the stomach was actually a consequence of severe headaches and migraines.

So she told me to go to a neurologist for evaluation and treatment. I went to the neurologist, did tests, treatment, tried to avoid the huge list of foods he I was informed as probable triggers of migraine. Everything I did reduced the headaches, but it did not solve the problem that plagued me.

And it was during one of my “crises” of headache that a coworker commented the possibility that I would make an evaluation with a dentist who had treated him when had problems with the TMJ. To be honest, I had no idea what it was, but when if you have pain, every attempt is valid.

47 DEPOIMENTO 3I made the appointment, made available the exams I had already done in the region of the head and remember that in my first conversation with Lidia she commented that the exams indicated that in my infancy I had probably suffered a fall that caused a growth modification of my jaw.

Exactly the side where I had the headaches and the migraine.

I stress that at no time did the treatment for an aesthetic question, but rather seeking, if it is not possible to avoid the pains, but minimizes them.

I spent several years attending the clinic. I remember that my splint in one of the stages of the treatment was a “big monster” (kkk) considering its height.

Gradually throughout the treatment I was noticing the reduction of headaches and of frequency between migraine attacks.

Today, thinking about before and after treatment, I realize how much the treatment,

although prolonged, has improved my quality of life.

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.

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.

17 ABERTURA E FECH COMPARATIVOSPatient’s kinesiographic records comparison:  before treatment in the habitual occlusion and with the DIO (intraoral device) in neurophysiological position constructed above the patient’s prosthesis.

18 CICLOS MASTIGATORIOS COM DIOPatient’s masticatory cycles after the neurophysiological treatment.

In this graph the left side chewing appears on the left side as it corresponds.

In the previous graph before treatment in habitual occlusion, the left side chewing graphic appeared on the right side due to mandibular torque.

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.
