Résumé
Bruxism is an unconscious behavior characterized by contractions of the masticatory muscles outside the physiological functions. The dentist is required to manage the oral consequences of bruxism; the most remarkable one is dental wear. When the dental degree of damage becomes important, a total fixed prosthetic treatment must be conceived. The prosthetic rehabilitation aims at restoring all the occlusal functions [centering, guidance], to allow the entire masticatory system to operate with minimal constraints. It must redefine esthetic criteria, reestablish a good functional occlusal stability and optimize the functions of the masticatory system. These basic concepts are illustrated by the presentation of a clinical case of a patient suffering from bruxism
