TMJ Pathologies Treatment: Patient with Severe Headaches and Temporomandibular Joint Pain with Significant Contour Irregularities in the Mandibular Condyle and Mouth Opening Limitation.

In several publications of this page I have presented patients of different ages, different gender and different pathologies of the temporomandibular joints.

This is the second case report about a patient with prosthetic protocols built on implants.

I call once again the importance of  the attention in the diagnosis of temporomandibular joints pathologies and mandibular position as a key part of any procedure in dentistry.

1 FOTO INIC FRONTAL

Female patient 54 years old arrived to the clinic for consultation with severe headache complaints, pain in the temporomandibular joints, pain in the cervical spine, sore shoulders, ear pain, feeling of clogged ears and crepitation in both temporomandibular joints.

MRI, sagittal slice of the right TMJ closed mouth: there is an irregularity of contour with reduction of the superior aspect of the mandibular condyle, the condyle is ante versioned. There is a small anterior osteophyte.

The articular disc is displaced anteriorly, WITHOUT REDUCTION when the mouth opens.

Presence of subcortical bone cysts in the anterior superior aspect of the mandibular condyle.

13 RNM  ESQ  INICIAL

MRI, sagittal slice of the left TMJ closed mouth: there is a substantial irregularity of contour of the upper portion of the mandibular condyle, with the formation of an anterior osteophyte.

There is a rectification of the articular eminence.

The disc has reduced dimensions lying anteriorly displaced WITHOUT REDUCTION when the mouth opens.

Can be seen an important hipossinal compatible with avascular necrosis.

13A RNM  ESQ  INICIAL

Can be seen an important hipossinal compatible with avascular necrosis.

16A  ESQ boca fechada 2013 T2

MRI in T2 clearly shows the joint effusion.

The differential diagnosis of TMJ effusion has a broad spectrum as the effusions in other joints in other parts of the skeleton.

MRI (magnetic resonance imaging) can give us a lot of information, not just the disc position.

In the slice of the mandibular head on the left side can be seen an important hipossinal compatible with avascular necrosis.

Avascular necrosis occurs when blood flow to a bone is interrupted or reduced. It can be caused by various conditions, such as bone or joint damage, pressure inside the bone and other medical conditions.

The condyle affected by avascular necrosis has low signal on T1-weighted images as a result of edematous changes in trabecular bone.

Tests were done on the patient to investigate systemic inflammatory disease, which were all negative.

It was also investigated chlamydia trachomatis infections, mycoplasma pneumoniae infections and beta hemolytic streptococcus infections , results in this case were also negative.

It was also investigated the functioning of the thyroid.

17 REGISTRO CINECIOGRAFICO INICIAL

The masticatory muscles of the patient were electronically deprogrammed and DIO (intraoral device) was constructed in neurophysiological position. In other publications computerized kinesiographic methods were mentioned.

In occlusion most often the healthy or pathological condition of the inter-oclusal space is not objectively considered. In this case the free space of the pathological patient is almost 7 mm and a retro position 0 8 mm.

18 DIO SOBRE A PROTESES

With this data and ALWAYS WITH THE INFORMATION OF IMAGES, we built a DIO (intraoral device) to keep the three-dimensionally recorded position.

This device must be tested electromyographically to objectively measure the patient.

19 CONTROLE DA ORTESE

It is essential to control the DIO (intra oral device) as the patient is treated and the mandible is repositioned.

In this case the control still shows us the need for recalibration of the DIO (intraoral device)

28 DEPOIMENTO

“Headache (already when waking up in the morning), tiredness sensation at the cheekbones, strong tensing at the shoulders and neck, “clicks” at the temporomandibular joint, ear pain… consequently I also felt irritation, indisposition, stress etc.

All of that is something I had to live with for a long time. The investigations made on me always resulted in palliative measures that mitigated the problem for a short time.

I passed through implants and placement of prostheses which even without having (those measurements) the aim of healing this malaise I still had the hope that it would: but the relief only worked for a short period of time. Finally, by indication of my dentist, I arrived at Clinic MY starting then the TMJ treatment. Shortly after the start of the treatment the symptoms started to fade.

I am very thankful for the professionalism and dedication that I found there. Today, feeling better, I go back there for periodic evaluations and also to have the opportunity of thanking  once more.”

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.

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.
