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.

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.

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.

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.

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.

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.

14

Comparison of the two electromyography records the first in habitual occlusion and the second with the intraoral device in neurophysiologic position. The masseters present excellent activity with the DIO, compare the first initial record where these muscles couldn’t activate.

15

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.

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.

25

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.
