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.

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.

Mandible Condyle Fracture Consolidation by Neuromuscular physiological 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.

9 0clusão com o DIO

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.
