Dental and Oral Health

The search for occlusal balance must constantly guide the general practitioner in his daily exercise. This is even truer when our patient's mouth needs to be restored and this becomes even essential in the event of need for restoration in the presence of Temporo Mandibular Disorder (TMD) or history of TMD. The first step in this search for occlusal equilibrium is, of course, the analysis of

occlusion, to estimate the excellence of 0IM, from the point of view of wedging, centering and guiding. This analysis will be clinical

and if necessary, instrumental (on semi-adaptable articulator). The clinical observation will of course appeal to the practitioner's eye, but also to occlusal markers of varying thickness. It is necessary to ask the question of the validity of the traces left by these markers (false positives and false negatives). The presentation will focus on three important stages of occlusion analysis: Observe, simulate and optimize. The articulator analysis will allow considering the occlusal modifications to achieve to improve the occlusal conditions,

the occlusal scheme. This analysis will inform the practitioner about the feasibility of pre-prosthetic occlusal equilibration. It will also make it possible to choose the subtraction (selective grinding) or the addition (by gluing of composite according to the ceroplasty). The simplest means to implement and the least dilapidated will always be recommended to respect the principle of therapeutic gradient and tissue economy. The contribution of direct or indirect composite bonding techniques (Inlay-on lays) in the optimization of calibration

and guidance will be detailed .
