Abstract: The healthy temporomandibular joint (TMJ) is of vital importance to basic physiological functions such as mastication, swallowing, and speech. Temporomandibular joint disorders are possibly related to abnormal stress distribution in the TMJ. However, it is not feasible to directly measure the complex stress and strain distribution patterns in the TMJ by conventional measurements. Dynamic three-dimensional finite element analysis has become the main method to study the biomechanics of TMJ due to its accurate and non-invasive nature. However, there are significant differences in the geometric similarity and degree of mechanical simulation between different modelling methods. In this paper, the geometric model construction, material properties, contact relationship, and the kinematic loading of TMJ are reviewed.

Key words: temporomandibular joint, finite element modeling, kinetic simulation, computational biomechanics
