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!

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 electromyography and kinesiography records objectively showed improvement of the neuromuscular function.

I asked for the second MRI (nuclear magnetic resonance) to objectively evaluate the physiological relationship between the mandibular condyles and the articular disc.

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.

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.

Female patient 22 years old comes to the clinic with a strong headache principally on the top, pain on both temporalis, pain on the back of the head and on the shoulders.

Difficulty in chewing hard food, crepitations on both temporomandibular joints.

She reports bruxism since childhood.

Patient´s testimony

Since I was very little my parents reported that I had bruxism at night

3b dinamico habitual

Surface electromyography, dynamic record in habitual occlusion. We ask to the patient to open the mouth, to close the mouth, to bite strong and to swallow. In this patient’s electromyography record we observe little activity in the masseters and anterior temporalis. We can also observe asymmetry between the right and left temporalis. It is obvious that the masseters have a loss of activity in the middle of the maximal occlusion.

4 PANORAMICA Patient’s initial panoramic radiograph before treatment.5LAMINOGRAFIA INICIAL

TMJ laminography of the patient before treatment in habitual occlusion and opening. Asymmetry of the mandibular heads. Superior and posterior position of the articular process of the right side in the joint cavity, provoking a retrodiscal compression.

We observe asymmetry between the left and right mandibular heads.

Alteration of the axis of the right mandibular condyle.

Patient´s testimony:

When I was 5 years old, while I was playing in the  pre school class interval  I had a traumatism.

A seesaw hit my chin when I was playing with another girl. They put ice on my chin to reduce the swelling. There was no much pain or apparent fracture.

I did not perform medical tests.

I remember another traumatism I had when I was 13 years old, I slipped on the sidewalk and felt hitting my chin on the ground, I FRACTURED THE UPPER INCISORS,  (they have resin)

Sometimes I wake up and I feel that I´m biting and moving my mandible.

If I don´t use the bruxism splint to sleep I brake the resin of my teeth.

The splint protects the resin, BUT DOESN´T ALLIVIATE THE PAIN.
