Recapturing the Articular Disc or Repositioning the Mandibular Condyle? What about Rethinking the Concept as the Recovery of the Physiological Relationship of the Head of the Mandible with the Articular Disc. Patients with a long history of pain. Case series. First Section.

Recapture the articular disc, repositioning the mandibular condyle?

What about rethinking the concept as the recovery of the physiological relationship of the mandible head with the articular disc ,WHEN IT IS POSSIBLE.

And when is it not possible? What is the differential diagnosis? WHAT CAN WE OFFER TO OUR PATIENTS?

What type of orthotic or intraoral device to use? What is the purpose of an orthotic  in a TMJ Pathology treatment? Repositioning the jaw, recapturing the articular discs? Is this always possible? DEPEND ON THE DIFFERENTIAL DIAGNOSIS!

Does it have changes in the articular structures of the temporomandibular joint?

Does it have distortions in the horizontal, vertical and transverse posture of the craniomandibular complex?

How are the bones?

How’s the cartilage?

How’s the articular disk?

How are the muscles in this system?

How is the cervical spine in relation to the whole system?

How is the relation of the vertebral column with the other parts of the system?

The teeth, the two temporomandibular joints and the postural musculature are parts of the same bone, the mandible. They are deeply interrelated and interdependent in growth, form, and function. An abnormality in one, profoundly affects the others.

A 30-year-old female patient presents at the clinic with a history of headache, pain in the forehead, pain and stiffness in the nape of the neck, left eyebrow pain, pain behind the right eye, and pain in the right shoulder. The patient reports TMJ pain (temporomandibular joint) on the right side.

The patient reports bilateral crackling, non-specific facial pain, and muscle tremor, difficulty opening the mouth, difficulty in chewing and mandibular locking.

Summary report written by the patient:

I do not remember a sudden drop where there might have been some kind of injury.
At 6 years of age I was a gymnast. I always had falls, front, back and head. But there were protections on the floor.

Near 8 years old, I extract a molar from the lower left side. I think that from this I have always forced more chewing on the right side.

At approximately 13/14 years of age, I remember starting the cracks on the right side. On this side I had a cross bite and a deciduous canine that “bit” behind the lower tooth.

At this stage, the crackling became more frequent, causing a bit of difficulty to fully open the mouth.  When trying to open the mouth without the snap, the opening becomes smaller than after the click. That is, if I do not play with the jaw, the mouth does not open completely.

In 2004 I had the first “lockup”. I remember being in winter and cold. I tried to do the “game” of the jaw and I could not open the mouth. Then I forced myself to open my mouth and I felt a strong crack, followed by pain in the ear / nose. The impression was that it had displaced some bone / nerve.

From this episode, whenever I force more the region, the locking happens. Ex: when I eat meats, candy, peanuts. Things that I need to force when chewing.

In 2008 I put orthodontic appliance to make the corrections. In the treatment, I made a process of spacing the teeth, with a device in the roof of the mouth to open the arch. I kept my teeth apart for a while.

After finishing the treatment, corrected the teeth, the clicks returned lighter. Approximately 1 year later, the locking returned as well. I started with headaches and cervical pain. I felt slight tingling in the head.

In 2015 I started to hear some kind of “sand” on the left side. Then I got pregnant and in this period began the crackling also on the left side. In February 2017 I had the first “lock” on the left side.

Now when I feel the locking, I try to relax the muscles well, leaving the jaw loose for a few minutes. Sometimes it returns to normal anyway, other times I have to force it with the opening of the mouth, causing a strong crack.

Current information:

When I close my mouth, I feel my jaw line back slightly, to “marry” the bite. To keep my mouth “loose” and comfortable, I have to snap both sides, and let the jaw loose.

When I try to open my mouth without the snaps, the opening becomes smaller than after the click. That is, if I do not play with the jaw, the mouth does not open completely.

Crashes usually occur:

– Yawning;

– In the morning (awake with the jaw locked);

– Eating meats.

CT: Part of the initial study of the patient sent before the consultation requested by another professional.

Anamnesis and clinical examination are a key part in the diagnosis of patients with TMJ pathology.

Computed tomography is an excellent image, but when we treat a synovial joint in a patient with TMJ pathologies, CT does NOT PROVIDE THE INFORMATION OF THE SOFT TISSUES.

Magnetic Nuclear Resonance (NMR) can give a lot of information and not just the position of the disk. It is essential to have the knowledge to KNOW WHAT TO DO WITH THIS INFORMATION.

We cannot treat a patient with mandible head necrosis or with medullary edema or arthrosis or rheumatoid arthritis or lupus in the same way that we treat another patient with only a wrong position of the jaw.

The temporomandibular joints of all these patients need to be decompressed, but that is only part of the problem.

cicatriz do queixoThree-dimensional asymmetries in the head of the condyle may have been caused by different etiologies and cause morphofunctional pathologies.

Changes in the orientation of the mandible head occur in patients who have suffered blows in the chin region, either anteroposterior, vertical or lateral. We can observe in these cases a deformation of the head of the mandible in the form of curvature, with an anterior concavity, which in some cases may be so important which produces a compression of the retrodiscal region, causing severe symptoms.

25 registro cineciografico inicial

Patient’s initial record for the construction of the DIO ( intraoral device)

To correctly evaluate the Maxilomandibular 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 in this first record a pathological free space of 6,4 mm. 

The patient also presented a 0.4 mm  of mandibular retro position.

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

28 ortoseOcclusion of the patient with the DIO (intraoral device)

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

The PHYSIOLOGICAL NEUROMUSCULAR 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.

29 controle da orteseAnother cinecigraphic record to control the DIO (intraoral device) in a physiological neuromuscular position as the device is changed or recalibrated.

The patient did not report any more symptomatology. The comparative MRI showed the recovery of the physiological relationship of the mandible head with the articular disc.

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

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

For this we use a three-dimensional orthodontic, where the teeth are erupted to the new physiological neuromuscular position.

46 depoimento 1Patient Testimony:

My first memory of locking joints was at age 15 or so.

I looked for orthodontic specialists; I made the necessary “adjustments”, but the locking and the pain still continued.

I looked for Dr. Lidia now at the age of 30, since other experts told me that only surgery would be possible in my case. And yet, without knowing exactly whether we would succeed.

After starting the first phase of treatment with the device, the pain ceased and never again I had the jaw locking that so frighten me.

47 depoimento 2

I adapted very easily to the treatment, I was and I am being much disciplined with the use of the device.

Now, as Dr. Lidia explained to me, with the discs already in the right place, we will pass for the second phase, for withdrawal of the device.

Today I’m having a routine without worry that I can “lock” at any time.

I’m very grateful to Dr. Lidia.

The importance of Mandibular Rest Position by Electronic Deprogramming in the Treatment of Temporomandibular Joint Pathologies, Orthodontic Diagnosis and Oral Rehabilitation. Case report.

1 frontal  Male patient 42 years old arrived to the clinic referring a strong complaint because of  the wear in his upper and  lower arch teeth, frequent breakage of teeth, intense bruxism, shoulder pain and pain in the cervical spine.2 perfil The patient reports an aesthetic problem in his appearance in relation to his frontal  and  profile semblance, and emphasizes that his teeth “are almost over.”3 DENTES In the image of the patient’s habitual occlusion we can observe the intense wear of the upper and lower teeth, especially the anterior sector.

The patient had consulted a colleague to replace an adhesive fixed prosthesis. This colleague,  Dr. Joao Souza  was then attending the TMJ  Pathologies Megarresidency program in our clinic in Porto Alegre.

Dr. Joao Souza while looking at the profile, occlusion and wear condition of the teeth, suggested a consultation in our clinic for an evaluation of both the TMJ and also  the non-surgical possibilities within the neurophysiological philosophy.

The patient had already a scheduled orthognathic surgery, but still considered interesting to make another assessment of his clinic case.4 OCLUSAL Analizing the occlusal view we can better see the high degree of wear and tear of the anterior upper and lower teeth.5 PANORAMICA INICIAL We can observe in the panoramic radiograph the absence of the dental elements 17, 15, 26, 28, 37, 36 and 45.

The elements 38 and 47 are endodontically  treated.6 LAMINOGRAFIA Patient’s TMJ laminography in habitual occlusion: we can observe the inferior and posterior positioning of the articular process on the left side, in the articular fossa, when the jaw is in maximal intercuspal position.

In the maximum opening position we can observe the flattening of the anterior surface of the right articular process. We can also observe the anterior angulation of the articular process, on the left side, with the flattening of its posterior and upper anterior surface.7 PERFIL E ROSTO Lateral radiograph in conjunction with the profile image of the patient before the treatment. This images highlight the aesthetic problem that afflicts the patient.8 FRONTAL INICIAL Patient’s frontal radiograph before treatment.9 C7 INICIAL Patient’s lateral radiograph and cervical spine before treatment.10 ELETROMIOGRAFIA INICIAL ANTES DO DEM Electromyographic record before electronic deprogramming in the first consultation: slightly elevated activity of the left masseter muscle  and both digastrics muscles at rest.

All these masticatory muscles lowered their values after the electronic deprogramming.11 ELETROMIOGRAFIA INICIAL APÓS DEM In this record we can see a decrease in the activity of masticatory muscles at rest after the electronic deprogramming.12 ELETROMIOGRAFIA INICIAIS COMPARATIVASComparative electromyographic records before and after electronic deprogramming of the patient first consultation.7 PERFIL E ROSTOAfter the mandibular electronic deprogramming, it was verified the pathological increase of the interocclusal free space. This information, along all the auxiliary diagnostic tests, allowed us to propose a non-surgical neurophysiological treatment for the patient.

First we needed to locate the jaw in balance with the muscles with a DIO (intraoral device) built in neurophysiological position.

Subsequently we needed to perform a three-dimensional orthodontics to maintain the neurophysiological position in conjunction with a neurophysiological rehabilitation while maintaining the muscle equilibrium  initially obtained. For this it is essential to measure and control the patient in each and all of these phases.

In this patient specific clinic case  the recovery of the free interocclusal space would provide very good aesthetic and functional result!

IT IS NOT IN ALL CASES that surgery can be avoided (EACH CASE IS A CASE) and even similar cases require a personalized assessment and a unique study.

The patient was informed of all treatment stages and analyzing all the alternatives the patient accepted our clinical proposal.

An MRI, (Magnetic Resonance Imaging) to analyze the disk and ligaments  condition of the TMJ, (temporomandibular joint) was requested. The MRI revealed that the discs and ligaments were in good health.

13 a It was used neural transcutaneous electrical stimulation (TENS) in the mandibular division of the trigeminal nerve (V) to relax the masticatory muscles and record the rest position of the jaw.

The patient had a pathological free space of 8 mm and a retrusion of 3.8 mm.

This three-dimensional mandibular rest position had been recorded in the form of an occlusal bite registration, which was later used to construct a DIO (intraoral device).13 Registration for the recalibration of the DIO (intraoral device) during the first phase of the neurophysiological treatment.14 ORTESE RECALIBRADA The DIO (intraoral device) is a removable mandibular device which in this case must be used during the day and night by the patient, including in the meals. This oral appliance is tested electromyographically and magnetographically to support this neurophysiological position.15 PERFIS COMPARATIVOSPatient profile images in habitual occlusion and in neurophysiological occlusion with the DIO (intraoral device) in mouth. 16 FRONTAL COMPARATIVOSPatient frontal images in habitual occlusion and in neurophysiological occlusion with the DIO (intraoral device) in mouth.19 PANORAMICA PREPARO PARA IMPLANTES 1Patient’s panoramic radiograph shows the orthodontic preparation for the installation of dental implants.19b PANORAMICA IMPLANTES 1Patient’s panoramic radiograph after the placement of first dental implants.20 ORTO 1After the placement of the dental implants I began the orthodontic movement for reconstruction of the anterior teeth with composite resin.21 REABILITAÇÃO E ORTO E IMPLANTESAfter the anterior movement of the anterior teeth the braces were temporarily removed to allow the reconstruction of the teeth with composite resin.

Case report.38 depoimento

I had already decided to have surgery for facial correction due to various problems such as wear of the teeth, bruxism, tingling, physical imbalance, pain and bad appearance.

In a consultation for a small dental procedure with Dr. Joao Souza, I was advised by him to get in contact with Dr. Lidia Yavich for a consultation in order to see if there was any chance, in my case, to avoid surgery and solve the problems I was having.

In the first consultation that I had with Dr. Lidia Yavich I was introduced to a facial and dental correction technique that gave me more security than surgery.

Dr. Lidia stated that THERE WERE CASES WHERE SURGERY WAS ABSOLUTELY NECESSARY, but that in my case there could be another alternative.

So, I started the treatment, and THAT really changed my daily life completely. Today I am very happy with the result achieved and the quality of life provided due to the disappearance of the above-reported symptoms.

I would like to place on record that in addition to the professionalism of the entire team of Clinica MY, especially Dr. Lidia, I had the privilege to make great friendships with special people, that will always be a part of my life. I also want to leave a special thanks to Dr.  Joao Souza, that with his recommendation made all this possible because he always strives for quality and the well-being of his patients.
