摘　　要：A finite element model of the temporomandibular joint （TMJ） and the human mandible was fabricated to study the effect of abnormal loading, such as awake and asleep bruxism, on the articular disc. A quasilinear viscoelastic model was used to simulate the behaviour of the disc. The viscoelastic nature of this tissue is shown to be an important factor when sustained （awake bruxism） or cyclic loading （sleep bruxism） is simulated. From the comparison of the two types of bruxism, it was seen that sustained clenching is the most detrimental activity for the TMJ disc, producing an overload that could lead to severe damage of this tissue.A finite element model of the temporomandibular joint （TMJ） and the human mandible was fabricated to study the effect of abnormal loading, such as awake and asleep bruxism, on the articular disc.
