The Influence of Occlusal Disharmony on Condylar Movement during Mastication

近年来，颞下颌关节紊乱病（TMD）患者的牙科护理有所增加。认为错牙合畸形是下颌功能障碍的主要原因。可能会影响颞下颌关节的原因。我们以前的研究表明咬合不协调是如何影响下颌骨内点运动的。本研究旨在探讨颞下颌关节紊乱病（TMD）发生的关键机制--髁突点的运动，研究髁突在边界运动和咀嚼运动中的三维运动。髁突运动模式与切牙运动模式有密切关系.结果表明，咀嚼时髁突的运动取决于髁突上的测点。

Recently, patients with temporomandibular disorders (TMD) have increased in dental care. It has considered that mandibular dysfunction, caused by malocclusion. May affect temporomandibular joints for this reason. Our previous studies has shown how occlusal disharmony affected Insisal point movement of mandibule. Condylar point movement must be also understood to investigate the critical mechanism of TMD.The purpose of this study was to investigate the three-dimensional movements of condyle during border movements and chewing movements.The results were as follows1. The condyle movement pattern has the close relation with the incisal movement pattern.2. It was attained that condyle movements depend on the measuring point on conclyle during mastication.
