Temporomandibular joint (TMJ) disorder relates to the mechanical irregularity of the structual joint components, and the behevior of soft tissue components is considered as a key to understand the biomechanical condition in the TMJ. In this study, the attention has been focused on the stress and displacement of articular disc in disorderd TMJ with anterior disc displacement (ADD). ADD-TMJs have been modelled by using biplane MRI technique and the effect of ligamentizations of posterior connective tissue following to ADD has been examined by means of computational biomechanic analysis based on individual finite element modelling since the configulation of the joint components deeply depends on individual patients. As the result of a parameter study, it is found that the ligamentizations of the posterior connective tissue is contribute to the load redistribution in ADD-TMJ and considered as a biomechanical adaptation for ADD.
