Les articulations temporo-mandibulaires (ATM) interviennent dans de nombreuses fonctions (alimentation, ventilation, communication verbale et non verbale) et se doivent d'être hautement adaptatives. Doté d'un potentiel hormono- et mécano- dépendant, la croissance de la mandibule et des ATM est assujettie aux contraintes mécaniques survenant tant pendant la période diurne que pendant le sommeil. Après un rappel des éléments anatomiques en présence, surfaces articulaires (condyle mandibulaire, disque et éminence temporal), moyens d'union, muscles, l'auteur détaille les différents mouvements des ATM et de la mandibule.
Anatomy and biomechanics of the temporomandibular joint (TMJ)
As the temporomandibular joint (TMJ) is involved in many functions (eating, breathing, verbal and nonverbal communication) it needs to be highly adaptive. Featuring a mechanical and hormone-dependent potential, growth of the mandible and the TMJ are subject to mechanical stresses occurring both during the daytime and during sleep. After reviewing the anatomy, the articular surfaces (mandibular condyle, disk and temporal eminence) and the muscles, the author details the different movements of the TMJ and the mandible.
