workshop lisboa 1

The advances in biotechnology have allowed a deeper understanding of the pathologies that affect the temporomandibular joint.

Nuclear magnetic resonance images and biotechnology were transferred to the realm of clinicians, no longer being exclusive to the realm of researchers.

These advances play a key role in conjunction with clinical examination, carefully integrated with the patient’s history and pathophysiology.

Controlling pain is a fundamental goal, but it is also possible today, in certain cases, to regenerate structures.

Cephalometry presupposes that the mandibular heads are in a physiological position and patients do not present any pathology in the temporomandibular joint.

Many of our patients looking for correction of a malocclusion, or a prosthetic rehabilitation, present noises in their TMJ, facets and erosions in their images and pain in the retrodiscal palpation.

Hard tissue injuries as a result of early childhood trauma can lead to injuries to the disc and ligaments.

Infections and autoimmune diseases should be considered, since they affect not only the temporomandibular joint but also all the fascial and muscular chains of the human body.

The evaluation of TMJ and the diagnosis of its pathologies should be an inseparable part of our procedures, not only in orthodontics and orthopedics but in all fields of dentistry.

The temporomandibular joint (TMJ) as a peripheral trigger in the headache. Physiological Neuromuscular Rehabilitation. First and second phase. Case Report.

1 FRENTEA 36-year-old female patient with a major complaint of headache consults at the clinic, referred by a co-worker who had been treated at the clinic for the same reason.

The patient’s main complaint was a high frequency headache. The patient reports that she has investigated the cause of the pain and even had at the request of the neurologist a nuclear magnetic resonance of the skull that did not accuse any abnormality.

1 PERFILThe patient had already consulted with Neurologist, Otorhinolaryngologist, Orthopedist and with the general practitioner.
The patient also refers back pain.

2 DENTES INICIAISHabitual occlusion of the patient on the day of the consultation.

3 OCLUSAISUpper and lower occlusal views of the patient on the day of the consultation.

Upper and lower incisors show signs of  attrition.

7 PANORAMICAInitial panoramic radiograph of the patient before treatment.

Absence of the second right upper premolar and the lower third molars.

The patient reports that the upper premolar was extracted in adolescence due to lack of space for the eruption of the canine.

The first maxillary molar on the left side and the first lower molar on the left side presented endodontic treatment with extensive restorations and risk of fracture, was informed of the need to extract the third molar retained.

The procedures would only be performed after joint decompression.

Primary objective has to be the three-dimensional decompression of the mandibular condyle.

8B CINECIOGRAFIA 1BThe patient’s masticatory muscles were deprogrammed electronically and the resting position was recorded with a computerized kinesiograph.
The patient had a pathological interocclusal free space of 6.3 mm and a mandibular retroposition of 0.5 mm.

9 ORTESEWith the record obtained with the computerized jaw tracker an intraoral device (DIO) was made to achieve the three dimensionally reposition of the mandible.

The PHYSIOLOGICAL NEUROMUSCULAR position was recorded in the form of an occlusal bite record, which was later used to make a DIO (intraoral device)

The patient did not report any TMJ-related symptomatology. 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 use a three-dimensional orthodontic, where the teeth are erupted to the new neurophysiological position.

In this specific sequence, another possibility was proposed for the patient with an important improvement of aesthetics for the increase of the clinical crowns of the upper incisors, due to the limitation in this case of the composite resins.

The patient alleged: that she did not work on television, that even knowing the aesthetic limitation of the procedure with resins, she was satisfied.

For her the goal of the treatment was the resolution of the PAIN, and that had been reached.

46 DEPOIMENTO 1Patient testimony

Dear Lidia,

You know, I really realized how much the treatment I’ve undergone improved my quality of life when I was in the clinic this year (2018) and I looked at my file with the information I had recorded when I started treatment.

To be honest I did not even remember that before the treatment I had pains in the jaw joints !! And how strong they were.

I always had headaches and migraines, besides the pains in the joint of the mandible. I always record it because I remember when I was a child I already felt them. I felt very ill and indisposed when I had crises.

In a certain phase of my life due to the increase in the frequency of pain headache and the constant vomiting I went to many doctors because I thought I was with stomach problem. I thought my headaches and migraines were consequence.

47 DEPOIMENTO 2But based on the examinations I made at the time, my general practice told me that the question of the stomach was actually a consequence of severe headaches and migraines.

So she told me to go to a neurologist for evaluation and treatment. I went to the neurologist, did tests, treatment, tried to avoid the huge list of foods he I was informed as probable triggers of migraine. Everything I did reduced the headaches, but it did not solve the problem that plagued me.

And it was during one of my “crises” of headache that a coworker commented the possibility that I would make an evaluation with a dentist who had treated him when had problems with the TMJ. To be honest, I had no idea what it was, but when if you have pain, every attempt is valid.

47 DEPOIMENTO 3I made the appointment, made available the exams I had already done in the region of the head and remember that in my first conversation with Lidia she commented that the exams indicated that in my infancy I had probably suffered a fall that caused a growth modification of my jaw.

Exactly the side where I had the headaches and the migraine.

I stress that at no time did the treatment for an aesthetic question, but rather seeking, if it is not possible to avoid the pains, but minimizes them.

I spent several years attending the clinic. I remember that my splint in one of the stages of the treatment was a “big monster” (kkk) considering its height.

Gradually throughout the treatment I was noticing the reduction of headaches and of frequency between migraine attacks.

Today, thinking about before and after treatment, I realize how much the treatment,

although prolonged, has improved my quality of life.

The Tridimensional Neurophysiological Position of the Mandible in Implant Prosthesis Protocol

Nowadays dentistry has new resources for prosthetic resolution of patients with extensive loss of their dental pieces.

New technologies allow protocols to build prostheses where before, they would have no support solution.

Out of aesthetic recovery, essential for the patient IT IS NECESSARY to have an initial point of mandibular rest position, as these complex cases make rehabilitation more challenging.

1 frontal INICIALMale patient 54 years of age arrived to the clinic for consultation referring pain and sensation of plugged ear, especially on the left side. Also refers pain on top of the head and pain in the left shoulder.

2 PERFIL INICIALThe patient reports stiffness and pain in the back of the neck, a different sensation on the left side of the head as tingling and loss of sensibility and “blocked ear”

Refers an uncomfortable sensation in the left eye, in his words says that “the eye is sensitive”.

Refers hand tremor.

3 protese inicialThe image of the patient’s habitual occlusion shows a Class III or mandibular prognathism.

The  patient reports the prognathism  condition even before the dental loss.

When we study occlusion most of the time we do not consider if the inter-occlusal space is healthy or pathologic.

4 oclusaisPatient’s superior and inferior oclusal view.

4A questionarioWhat most encourages the patient to seek treatment was the sensation of blocked ear and his desire to resolve the issue.

The patient also relates noises when chewing and fatigue of the masticatory muscles. The patient also reported a numbness sensation near the left ear.

The patient had been medicated by another professional with muscle relaxant, but he did not feel any symptoms change.

5 PANORAMICA INICIALPatient’s initial panoramic radiograph before neurophysiological  treatment.

The patient has this protocol for more than 18 years.

The patient reported a periimplantitis history, and had no image prior to implant placement.

6 LAMINOGRAFIA INICIALPatient’s TMJ right and left laminography, closed and open mouth before neurophysiological  treatment.

7 TELERRADIOG INICIALPatient’s lateral radiograph in habitual occlusion before treatment.  Marked prognathic profile.

7A TELERRADIOG INICIAL LINHAMarking the aesthetic plane of  Ricketts in the lateral radiograph with the profile of the patient.

8 FRONTAL INICIALPatient’s frontal radiograph before treatment.

9 ELETROMIOGRAFIA INICIALPatient’s dynamic electromyography record in habitual occlusion before treatment.

In this dynamic record we registered the anterior right and left temporal muscles, the right and left masseter muscles, the right and left digastric muscles and the right and left upper trapezius muscles.

The right masseter muscle ALMOST CAN NOT RECRUIT MOTOR UNITS during maximum sustained  intercuspation, it can only generate 21 microvolts in the selected band.

Important asymmetry between the two masseter muscles, right and left.

10 ABERTURA E FECH INICIALPatient’s initial kinesiographic record: we can see a good speed when the mouth opens and a reduction of speed when the mouth closes.

There is no coincidence between the opening and closing trajectories in the sagittal view.

The opening movement has a propulsive closing and a lateralization in the frontal plane to the right of 8.2 mm.

11 CICLOS MASTIGATORIOS HABITUAL ANTES DO TRATThe patient’s masticatory cycles are registered with a jaw tracker. In the record of the masticatory cycles we used almonds to register chewing activity.

This post will not make a detailed analysis of this record. But it is important to note that: on the left side of the graph, even if the patient is chewing almonds on the left, THE GRAPHIC APPEARS ON THE RIGHT SIDE. This is due to mandibular torque that the patient needs to perform to chew.

11ARNMMRI: left and right TMJ closed mouth.  I chose this slice to show important asymmetry between the right and left side.

The left side shows a posterior dislocation of the articular disc. There is NO ARTICULAR DISC on the right side, is IMPORTANT TO MARK THIS, since in several posts I emphasized the importance of recapturing the disks when possible, (IN THIS CASE I CAN NOT RECAPTURE A STRUCTURE THAT DOES NOT EXIST).

In this particular case the request of resonance is part of the protocol to obtain fundamental information in the formulation of diagnosis.

Different slice and parameters do not show bone edema or other information requiring different interventions within the treatment.

The goal in this particularly case  will be the three-dimensional repositioning of the jaw, TO RECOVER the neurophysiological function, which should be widely understood, so that the muscles, temporomandibular joints and teeth and prostheses could work in balance.

12 JAW TRACKER BIOPACKTo determine the neurophysiological three-dimensional position of the jaw, even in cases of extensive rehabilitations we have to consider the physiological position of the mandibular rest.

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

The patient has a PATHOLOGICAL FREE WAY SPACE OF 7.2 mm. Maintaining the physiological 2 mm we still have more than five mm discrepancy, to be recovered tridimensionally.

The jaw also presents a retro position of almost two mm and a deflection at closing of 0.5 to the left side.

13 DENTES COM ORTESEWith this data and ALWAYS WITH THE IMAGES INFORMATION, we constructed a DIO (intraoral device) to keep the three-dimensionally recorded position.

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

13BTELERRADIOG COM DIOPatient’s lateral radiograph with the DIO in neurophysiological position.

13CTELERRADIOG COM DIO LINHAMarking the aesthetic plane of  Ricketts in the lateral radiograph with the DIO in neurophysiological position.

The DIO is an orthopedic device, recorded and controlled electromyographically. The DIO (intraoral device) is used to support, align and ameliorate deformities in order to improve the functions of the jaw, temporomandibular joints and the muscles.

14 ELETROMIOGRAFIAS COM o DIOPatient SEMG record with the DIO (intraoral device) in neurophysiological position built above the patient’s prosthesis.

We can note the improvement of the right masseter muscle activity. Before the treatment the right masseter muscle could not recruit motor units.

15 ELETROMIOGRAFIAS COMPARATIVASComparison of the SEMG records: before the treatment in habitual occlusion and with the DIO (intraoral device) in neurophysiological position built above the patient’s denture.

WE MUST CONSIDER that years of muscle accommodation and the central nervous system engrams cannot be modified with a first orthotic or DIO

That’s why the DIO should be adapted, changed, and recalibrated to follow dimensional changes that will happen when muscles are aligned.

16 ABERTURA E FECH COM O DIOPatient’s kinesiographic record after neurophysiological treatment.

Significant improvement in the opening and closing trajectories.

The closure no longer has a propulsive trajectory.

The lateralization which was 8.2 mm was reduced to 2 mm.

17 ABERTURA E FECH COMPARATIVOSPatient’s kinesiographic records comparison:  before treatment in the habitual occlusion and with the DIO (intraoral device) in neurophysiological position constructed above the patient’s prosthesis.

18 CICLOS MASTIGATORIOS COM DIOPatient’s masticatory cycles after the neurophysiological treatment.

In this graph the left side chewing appears on the left side as it corresponds.

In the previous graph before treatment in habitual occlusion, the left side chewing graphic appeared on the right side due to mandibular torque.

And here, the words of Confucius: A picture is worth a thousand words.

27 Patient testimonyI lived for a long time with discomfort that sometimes manifested itself by a feeling of numbness and sometimes by headaches.

I could not identify the cause; although I repeatedly searched for expert help.

On the recommendation of my sister and my sister in law who were being treated by Dr. Lidia I consulted her and started a treatment which lasted a long period, getting excellent results and today I feel good without the symptoms that hindered me so much.

I appreciate the commitment and dedication of Dr. Lidia and her team.
