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.

13C PRIMEIRA ORTESE LUIS

With 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.

46 DEPOIMENTO 1

At the end of 2012, I attended the Life and Health program on RBS TV and saw a report with Dr. Luis Daniel Yavich Mattos, on the treatment of problems related to TMJ.

Living with constant headaches, jaw pain and daily pressure on the teeth,

I decided to bet on the treatment and I do not regret it.

Since I was 18 years old, I had been suffering from pain in the TMJ region, and what

bothered me was a pressure that made me want to grind my teeth even

day, which I have always identified as bruxism.

I had already sought out various dentists and treatments, with the use of the famous splints to sleep. The diagnosis was always the same: emotional stress was the cause of my teeth and constant pains, although the pains started only after I have extracted my first wisdom.

47 DEPOIMENTO 2

I used to use the plates to sleep during the 24 hours of the day, so the will of biting and grinding teeth. The use of the splints  prevented wear, but the pressure I felt to bite and grind my teeth caused me TMJ fatigue and headaches.

And when I had no more hope emerged, the possibility of doing the treatment with Dr. Luis Daniel and Dr. Lidia Yavich, when I was 32 years old.

With Dr. Luis Daniel they were approximately 1 year and 2 months  using a very high plate, 24 hours a day, including to make meals, which I only took to do the oral hygiene.

The device was called the “big monster,” because of the height. In the end, no longer  pain and without the will of grinding and biting my teeth.

I went on to the second stage of treatment, now with Dr. Lidia Yavich.

48 DEPOIMENTO 3

With Dr. Lidia were approximately 3 years, in which I used fixed dental appliance, with brackets, steel wires, etc., in order to be able to stop using the board 24 hours a day, and improve the aesthetics of my dental arch.

As the treatment progressed, the device was diminished and new splints were used in order of erupting my teeth respecting the TMJ position.

At the end of the treatment, I now use one sleeping device and another one for aesthetic reasons.

I no longer have the willingness to bite and grind teeth, or pain in the TMJ or headaches. I can yawn without worrying about hurting my jaw.

Finally, it was an individualized, artisanal treatment that required time and dedication, and brought excellent results, which is why I am eternally grateful to Dr. Luis Daniel and to Dr. Lidia.

 

Mandible Condyle Fracture Consolidation by Neurophysiological Alignment of the Segments, Four Months after Unsuccessful Surgery. Case report

Fractures of the mandibular condyle are one of the most commonly occurring mandibular fractures. Management of these fractures has always been a controversial issue. One of the complications of mandibular condyle fracture is nonunion.

This case report documents a 57-year-old male patient with a complication nonunion of the left mandibular condyle 4 months after surgery and the resolution of this case with a neurophysiological alignment of the segments, without a new surgery or internal fixation.

1 AA 57 year-old male patient was referred to the clinic by his dentist. His principal complaints were lack of strength when chewing, difficulty in opening the mouth, cervical pain, pain in the TMJs and ringing in the left ear.

Past history revealed that the patient fell in the bathroom 4 months before the consultation, hitting his jaw and fracturing his mandible. He was subsequently surgically treated for fracture of the symphysis and the left mandibular condyle.

Extra oral examination did not reveal any obvious swelling. 1 BAfter performing all the clinical evaluations a panoramic radiograph was solicited where the nonunion of the left condyle was noticed.

Dental abnormalities included missing 14, 36 and 46 and a posterior open bite on the left side.

Based on the case history it´s clinical and radiographic features, this case was diagnosed as nonunion fracture of the left mandibular condyle . Nonunion is a complication in mandibular fractures. The causative factors include delay in treatment, infection, inadequate immobilization, and improper internal fixation; concomitant infection may be present.

Other suspected contributory factors include failure to provide antibiotics, delay in treatment, teeth in the fracture line, alcohol and drug abuse, inexperience of the surgeon, and lack of patient compliance.

Generally treatment of nonunion consists of standard techniques of debridement, antibiotic therapy and further immobilization.1 A

We referred the patient back to the surgeon where a new surgery was proposed.

THE PATIENT ABSOLUTELY REFUSED TO HAVE A NEW SURGERY

Considering the categorical decision of not performing a new surgery the patient returned to the clinic and a conservative approach to treatment was proposed. The patient was informed about possible limitations due to his age.

Analyzing the alternatives  he accepted the clinic’s proposal.

8 REGISTRO INICIALUltra low frequency and low amplitude, transcutaneous electrical neural stimulation (TENS) of the mandibular division of the trigeminal nerve (V) was used to relax the masticatory muscles to record the rest position of the mandible.

That tridimentional mandible rest position was recorded in the form of a bite occlusal registration, which was later used to fabricate a Intraoral device. This is a removable mandibular appliance that in this case must be worn during day and night by the patient. This intraoral appliance, tested electromiographically and magne­tographically, support this neurophysiological position.

The patient was asked to wear the intraoral appliance full time. The dynamic evaluations improved and the patient felt no more pain, and no difficulty to chew.

During the treatment  new intraoral device in neurophysiological position was constructed.10  0clusão com o 2 DIOA second panoramic radiograph was solicited after three months. The new panoramic radiograph showed the improvement of the condyle position and finally, four months after this control a third panoramic radiograph was solicited where we can see the union of the fracture. 11 comparação de panorâmicas Comparative image of the left mandibular condyle of the first panoramic radiograph of the patient on the day of consultation (4A), second panoramic radiograph three months after (4B) and third panoramic radiograph (4C) four months after the second control showing the improvement of condyle position and the union bone.

Fractures where the muscles tend to draw fragments together are more favorable than those fractures where the muscles tend to draw fragments apart.

The displacement of fracture fragments is observed in mandibular condyle fractures. The most commonly observed type is the displacement of the condyle head to the anteromedial side because of lateral pterygoid muscle action.

The ability to place the mandible in a spatial relationship by measuring the masticatory muscles at their rest length can be an important auxiliary tool to assist in the recuperation of condylar fractures.
