Temporomandibular joint (TMJ) disorder relates to the mechanical irregularity of the structual joint components, and disc behevior is considered as a key to understand the biomechanical condition in the TMJ. Permanent anterior disc displacement and derangement are typical finding in TMJ disorder. The mouth opening motion naturally induces the anterior disc displacement tentatively even in normal TMJ, and the condyle motion is considered as the key to understand the disc displacement and stress. This study examined the influence of condyle trajectory on the disc displacement and stress of irregular TMJs with anterior disc displacement (ADD) in the context of finite element analysis with individual modeling.
