Abstract

The temporomandibular joint (TMJ) is composed by the mandibular condyle, the temporal fossa and an articular disc in between. The TMJ can be seriously damaged as a result of bone or dental disorders. To perform joint reconstruction and design prostheses, there is a need to better understand the TMJ 3D kinematics to estimate the joint reactions and disc contribution. In the literature, mandibular movements were used to describe TMJ kinematics but the studies have been carried out on small groups (<30) [1-4]. Besides, coupled studies of TMJ kinematics and dynamics are rather rare. Finally, no comparison of healthy and pathological subjects was done. This work aims to analyze TMJ kinematics and dynamics for large groups of asymptomatic and toothless subjects.
