Fatores que interferem na amplitude dos movimentos mandibulares em crianças

Abstract

Conflict of interest: non-existent temporomandibular joint (TMJ) 1 . The morphology of TMJ in newborn presents with flattening of the articular cavity, without the presence of articular eminence for the function of suction is feasible. Subsequently, they begin to perform more elaborated and coordinated mandibular movements, generating the development of the articular eminence that allows the realization of biomechanics, promoting mandibular movements of mouth opening, lateral and protrusion 2 . In this, the condylar movements are not only determined by the articular eminence, disc and the ligaments of the TMJ, as well as for occlusal and neuromuscular 3 factors. The static and dynamic relations between anatomical structures of the TMJ, occlusal areas and their functional relation participate in the normal and pathological process of temporomandibular system functions 4 .
