GLOSSARY

Training offered at the I.D.A.L. focuses on acquiring theoretical knowledge followed by practical applications.

Occlusion
Many practitioners mention that they refrain from occlusion because they feel insecure or lack knowledge. However, dentists working in the area of dental surgery, cosmetic dentistry and removable, permanent (implant or non-implant) will inevitably perform occlusion.

Definition of occlusion  
Occlusion is usually assessed in a fixed state in other words, in the normal occlusion of the patient. It is necessary to assess the patient in a dynamic situation of occlusion during the phonetic and mastication functions.

Parafunction 
«Parafunction» is a term often used to refer to the clenching and grinding of teeth, phenomena related to stress management. Recent studies show that they may even be beneficial to an individual’s overall health.

Maxillo-mandibular relation
The relation between the mandibule and maxillary results from the movement of the mandibule during the execution of different functions of the mastication system.

Training
Our Institute prioritizes the assessment, functions and dysfunctions of the mastication system. This distinguishes training offered by our Institute from others.

Elaboration of treatment plans.

The overall health condition of the patient is taken into account.

Condylography

Modern condylography emerged in the mid 80s. (Slavicek and Mack). Pantography (e.q. Stuart) was its predecessor. As far back as the late 1800s, dentists were interested in the dislocation of condyles in the glenoïd cavities. (Gysi and Campion).

The electronic era signified the arrival of electronic and computerized condylography which simplifies the task on collecting data about the dislocation of each condyle. It also offers the possibility of an enhanced analysis of condylian dislocations. Therefore, the analysis of occlusion is no longer fixed but dynamic because of the condylography.

Determinants of occlusion

Everyone agrees on the importance of having an adequate posterior support and an anterior form of guidance to avoid posterior interference during different mandibular movements (e.g. canine guidance, group function), but very few people take one of the most important determinants of occlusion into consideration of A.T.M.

Functions of A.T.M.

A.T.M. are the starting points for mandibular movements. They have to have a stable and static position and must have harmonious movements during the different functions of the masticatory system. Their main movements are rotation and translation.

Condylography allows for the analysis of their movements on three spatial planes. Electronic condylography (GAMMA V5) even allows for the differentiation between the rotation and translation movements.

The average angulation of the translation of the condyles is around 48◦. The average occlusal plane presents an average inclination of 12◦ compared to the Frankfurt plane.

When the condyle’s translation inclination decreases (in certain cases of arthrosis, up to 15◦), we have to posteriorly decrease the occlusal plane (lower angulation compared to the Frankfurt plane) in order to avoid posterior interference.

Inversely, when we see a condyle’s translation inclination that is too accentuated (up to 70◦ compared to the Frankfurt plane), we must posteriorly increase the occlusal plane to offer our patients better efficiency in mastication.

Controlled Mandibular Repositioning (C.M.R.)

C.M.R. is a method that has demonstrated its effectiveness since 1994, for the treatment of reducible luxation (95% success rate) and the reduction of myalgias (success rate of more than 95%) without medication, at two-hour intervals. This proven method can also be used to treat cases of chronic non-reducible luxations and cases of arthrosis/arthritis.

Controlled Mandibular Repositioning (C.M.R.) is based on a complete clinical examination which takes into account all aspects of the mastication system, a complete functional analysis by an electronic condylgraphy (GAMMA V5) and the use of a “variateur” of mandibular positioning (Girrbach).

Many clinicians who received training from our Institute consider C.M.R. a clinically-proven method for treating Cranio-Mandibular Disorders.
