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.

24 COMPARATIVAS FRONTAIS POSTURAIS

Comparative frontal postural images.

The patient was derived along with TMJ pathology treatment for a physiotherapy team in the city where she resides. Along with mandibular repositioning the conditioning of all postural chains is necessary.

Each patient needs a specific derivation according to the particular case.

38 panoramicas comparativas

Comparative panoramic radiographs of the patient before starting the treatment and at the beginning of the second phase of the treatment. At this time the removal of the third molars included can also be done.

39 laminografias comparativas

Comparative laminographies of the patient before starting the treatment and at the beginning of the second phase of the treatment. The joint decompression can be observed.

Laminographs and or COMPUTERIZED TOMOGRAPHS, even showing decompression DO NOT SHOW the position of the articular disc. 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.
