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.

Postural Improvement in a Patient after Neuromuscular Physiological Mandible Repositioning Treatment. Patient with Scoliosis Surgery and Craniomandibular Symptomatology

The interrelationship between mandibular posture, occlusion and body posture is a topic covered by different health professionals.

When we speak of occlusion we do not mean only the relationship between the dental arches but we are also referring to the balance between teeth, muscles and temporomandibular joint in connection with all the postural scheme. In that way we can see and analyze patient as a whole.

This clinical case report describes a patient who came to the clinic for consultation after a scoliosis surgery, with craniomandibular symptoms and loss of vertical dimension.

Scoliosis is a three-dimensional structural deformation of the spine.

Idiopathic scoliosis is probably multi aetiological

The prevalence of the association between scoliosis and craniofacial anomalies should stimulate multidisciplinary collaboration on treating these patients, especially when we have an early diagnosis.

1 a

Patient narrative: brief history of the surgery:

When I was 14 years old I was diagnosed with scoliosis, after being noticed with a deformation on the back. Several medical experts were consulted and they stated the same diagnosis, however none of them could tell the causes, and they added that it could be related  to a malformation, some `trauma` in the growth phase, maybe being a hereditary problem.

“My mother noticed that the left side of my back was higher than the right side. In this period I also had frequently faints. Therefore, tests were performed, such as blood tests, electrocardiogram and electroencephalogram. They did not present any alteration”

“Concerned about the situation we consulted an orthopedic surgeon who ordered the realization of a panoramic X-ray of the spine. That test  showed a lumbar scoliosis of 25 degrees, for which the doctor recommended physical therapy.”

1 B JANELA

Panoramic radiographs of the spine were photographed on a glass of the window on day light, that’s why we can observe elements of the landscape.

22- 10 -2004  1

Cervicothoracic  Scoliosis. Left convexity, Cobb angle of 25 degrees. No significant pelvic difference.

“Initially, with about 25 degrees of curvature, I did physical therapy sessions and follow-up for a month.”

“I also used an insole ( which I stopped using it  because I did not perceive results and I felt no need) at the time I was also treating a cross bite.”

25-08-2004   2

Thoracic-lumbar scoliosis, left convexity, C0bb angle of 44 degrees. Accentuation of lumbar lordosis difference of the femoral heads of 3 mm.

“Clinical tests revealed that the curvature had evolved progressively to more than the double in size, reaching approximately 45 degrees. At the time, the proposed solution was the use of a neck vest in order to curb this trend.”

4-11-2004  3

X-rays taken for scoliosis treatment control with orthopedic brace.

“The vest was being used 22 hours per day, and it was also recommended swimming lessons for greater flexibility and aid in respiration in case of surgery.”

“During this period, there was a monitoring and vest readjustment in every month.”

“Finally, this alternative was not efficient enough, as the bending progressed to 64 degrees.”

“Thus, according to doctors, we reached the surgical case.”

At my 16 years old, I had the surgery on my spine. The recovery was gradual, nonetheless restfull. The pains, which were always absent, were felt not often in the hip area and legs. The bend in my spine regressed to 19 degrees.”

CONTROL REPORT OF COLUMN XR PANORAMIC SPINAL AFTER SURGERY:

Radiographic examination performed for surgical treatment control of Thoracic-lumbar scoliosis, left convexity fixed by metal screws and rods.

“After a year, I was released to engage in any sport mode, which until then I was forbidden to practice.”

REASON FOR THE CONSULTATION AT CLINIC MY:

“After dental treatment (crossbite) with another professional, mainly due to a shift in the cervical spine that I had tried to fix at the same time – but I did not had  another solution unless the surgery, which had already been completed – I was guided to proceed with Dra. Lidia, also to investigate the relationship between the two cases, so far no connection, the dental arch and the cervical spine. ”

“Following the derivation, I met Dr. Lidia to whom I presented my case, including the surgery of the spine, which led her to investigate the links that could be  cause and consequence of the whole problematic. After many conversations and clarifications I surrendered to the treatment.”

1The patient arrived to the clinic for consultation after a spine surgery, complaining of headache, frequent fatigue, pain behind the eyes, pain in the shoulders and clenching.

1 – Fall off a wall of approximately 1.50m tall. She fell on her back hitting the back of the head on the ground.

2- Sudden braking in the car. She was pushed against the windshield, but was held by her father.

3 – Bicycle fall. The pacient was taking a ride on the rack of a friend bycicle when she fell and and hits the mouth on the floor.

11A eletromiografia dinãmica habitualPatient’s electromyography record in habitual occlusion. Asymmetry between the right and left temporal muscles and asymmetry between the masseter muscles.

The most important thing in this case is the greater activity of the temporalis  muscles in relation to the masseter muscles. Remember that the muscles that must recruit more motor units in maximum intercuspation are the masseters and not the temporalis muscles.

12 registro neurofisiológico

Mandibular rest neurophysiological position record.

The masticatory muscles of the patient were electronically deprogrammed and a new neurophysiological rest position was recorded.

The patient had a pathological free way space of 5 mm and a shift to the right of 1,5 mm.

With the data obtained after the mandibular electronic deprogramming and ALWAYS WITH THE INFORMATION OBTAINED FROM THE IMAGES, a DIO (Intraoral device) in neurophysiological position was constructed.

In the first selection we can already observe a symmetry between the anterior temporalis muscles.

In the last selection with cotton rolls on both sides it can be observed an improvement in the recruitment of motor units in the masseters muscles and even lower recruitment in the anterior temporalis muscles. Remember that the DIO (Intraoral Device) is tested and calibrated  with Bioinstrumentation.

PATIENT TESTIMONY:

Especially the headaches (frontal) and the tension in the trapezius, along with the other listed symptoms, which hindered my work and productivity, were easily controlled with the treatment.

I am grateful to Dr. Lidia Yavich and the Clinica MY team for the profissionalism and which always had great care and attention, in the connection of the teeth, face and temporomandibular joint with the spine and posture.

For reasons of study and work opportunities, I chose to take a break in treatment, before starting a three-dimensional orthodontics.

I kept on inued with the continuous  use of the DIO – the pain is still being controlled – until I had the conditions to finalize the treatment.

Description of habitual orthostatic position in the sagittal and frontal planes

24

Sagittal plane:

The evaluation is described according to the plumb line test. This test takes into account the anatomical points that must be aligned with the vertical axis (plumb line) that is perpendicular to the horizontal axis (foot rest surface). The points are the lateral malleolus (specifically in calcanocuboidea joint), the joint center of the knee, the hip center (located in the femoral head), the lumbar vertebrae (L3 – L4), the center of the shoulder joint (acromion) and the external auditory meatus (ear ).

Picture 1 – patient in habitual occlusion before treatment:                     

 

It is observed that the patient is with the body in front of the plumb line. This shift of the reference points is observed from the knee joint in direct side view.

Picture 2: Patient using the intraoral device at the beginning of the treatment

Note that in this situation the patient is with the joint reference points ahead of the plumb line, but there was an approximation of the body segments shoulder and external auditory canal in the direction of the plumb line.

Image 3: patient using the intraoral device ready to move to a three-dimensional orthodontics

It is observed in this image that the patient is more aligned in upright posture, where all the reference points are aligned or closer to the vertical axis. The lower back and ear still remained ahead of the regency axis.

According to the three images it can be seen an improvement in the alignment of the orthostatic position in the sagittal plane throughout the treatment. Initially the patient was possibly with the muscles of the posterior chain overloaded from the soles of the feet to the suboccipital region.

Probably the use of intraoral device relieved such overloading .

25

Frontal plane

In the frontal view, the description of the usual orthostatic position is made in relation to the plumb (vertical axis) and two horizontal axes: horizontal axis of surface supporting feet and horizontal axis that passes just above the shoulders. The reference points in the frontal plane are: midpoint between the two feet, pubic symphysis, xiphoid process (sternum center) center of the cervical vertebrae (spinous processes) and the midpoint between the eyes.

Picture 1: Patient in habitual occlusion before treatment

It is observed the following displacements in relation to the vertical axis: slight displacement of the pubis point to the right side of the patient, followed by a displacement of the rib cage (xiphoid process) to the left side. The neck and head region are displaced to the left side of the vertical axis.

In relation to the horizontal axis of the bearing surface and from above the shoulders, it is observed that the right shoulder is lower than the right one. According to this image it can be said that she has escolise or that she is in a postural attitute presenting scoliosis.

Picture 2: Patient using the intraoral device at the beginning of treatment

In image 2 it is possible to observe that the position of the pelvis remained slightly shifted to the right side of the vertical axis. However there was an approximation of the xiphoid process (the center of the sternum) in relation to the vertical axis, as well as to the cervical vertebrae and head. These segments still kept themselves to the right side of the reference point.

In relation to the horizontal reference axis, there is a better alignment of the shoulders. The left shoulder remains in a lower position than the left one. In this image it can be said that the patient has a scoliotic attitude whith the lower spine angles of lateral flexing smallers, in other words there is a change in the support, right where  the scoliotic attitude is milder.

Image 3: patient using the intraoral device ready to move to a three-dimensional orthodontics

From this photo it can be seen that there has been an alignment of reference points of the pubis and the xiphoid process in relation to the vertical axis. In addition, there was a repositioning of the cervical vertebrae and head, where the  reference points are closer to the reference axis. In relation to the horizontal axis the image shows a balanced alignment of the shoulders.

From the three images of the frontal plane it can be observed that there was an improvement in the usual orthostatic posture, however there is still a displacement of the cervical and head reference points to the left side of the vertical axis.

It can be suggested that before treatment the patient showed a distribution of a possibly assimetric body weight between the right and left feet. The pelvis shifted to the right, generates such imbalance. In the  high thoracic and cervical region, probably there was a shortening of the muscles of the left side chain and an overload of the right side chain. With the DIO probably these imbalances  were mitigated  in the habitual orthostatic posture.

This evaluation in orthostatic position is not a dynamic evaluation of the patient.

I appreciate this assessment to Cintia Brino Baril, Master in Science of Human Movement UFRGS.
