TMJ Pathology in Professional Musicians: A look beyond the risk factors. Physiological Neuromuscular Rehabilitation. First and second phase. Case Report.

Several articles and studies cite the prevalence of TMJ dysfunction in violinists and violists, especially by prolonged flexion of the head and shoulder, posture necessary to keep the violin in position. Studies also report that the incidence of TMJ dysfunction in musicians is similar to the general population.

Professional musicians require many hours of training and improvement that involve complicated movements, fast and repetitive actions with over use of the hands, fingers, arms and head.

Most articles report anxiety about professional performance and increased muscle tension, but few do a particular study of the state of the anatomical structures of the cases studied.

1 postura inicial frontalA 45-year-old female patient referred by her physiotherapist consults with complaints of headache, pain in the cervical and scapular region, muscular contractures in the mandible.

The patient also reports mandibular displacement when playing the violin and pain in both temporomandibular joints.

2 postura inicial lateralThe patient also reports clicks in both temporomandibular joints and occasionally the sensation of clogged ears.

Frequent pain in the spine and both shoulders.

At that time the patient had already consulted physiotherapists, rheumatologists, psychiatrists and psychologists.

21 FRONT DIR E ESQMRI: frontal slice of right and left temporomandibular joints, closed mouth in habitual occlusion before treatment.

The frontal slice of the right temporomandibular joint shows a loss of joint space, especially in the region of the external lateral pole of the joint. Both frontal images show a decrease in joint space.

Slight medial disc deviation.

21A registro inicial para o DIOTo correctly evaluate the maxillomandibular 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 a pathological free space of 5.8 mm, already discounting the two physiological mm of a healthy free space.

The patient also presented a 2.1 mm mandibular retroposition

22 oclussao com o DIOWith 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.

It is logical that the report of the patient’s symptomatology is important, but the surface electromyography shows in an objective way if the muscular function improved, worsened or did not modify.

22A eletromiografia com o DIOElectromyographic record with DIO (intraoral device) in physiological neuromuscular position.

Note the higher recruitment of motor units in the masseter muscles that previously showed very little activity.

22A Registro cinesiográfico para controlar o DIO em posição neurofisiológicaCineciographic record for the DIO (intraoral device) control in physiological neuromuscular position as the device is changed or recalibrated.

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

Each case IS UNIQUE. There are cases where the TMJ structures are so damaged that the objectives outlined will have limitations dictated by the initial diagnosis.

These limitations refer not only to the structures of the temporomandibular joint, but also to the patient’s systemic condition.

The patient did not report any more symptomatology related to the TMJ. Bioinstrumentation also objectively showed an improvement in neuromuscular function.

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

For this we used a three-dimensional orthodontic, where the teeth are erupted to the new neurophysiological position.

Patient testimony:

What made me look for the treatment were recurrent headaches, frequent

(weekly) and intense, which lasted, on average, 2 days, affecting my productivity

at work as well as leisure hours.

The pain did not subside with common analgesics, requiring strong medication, which, in turn, only softened the pain a little.

Today, after the treatment, I can say that only very rarely do I suffer from these pains, greatly improving the quality of life, besides the posture.

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.
