项目摘要

Aim :The aim of the study was to investigate biomechanical relationship between asymmetry of human temporom andibular joint/occclusal scheme and the TMJ loading.Subjects :Ten female subjects with acceptable good occlusion participated in this study.Methods :By means of the 6DOF motion capture system, occlusal force, occlusal area and the 6DOF mandibular motion were simultaneously recorded. In each subject, gum-chewing was performed with/without insertion of artificial occlusal interference at the molar occlusal surface on the habitual chewing side.Results :The insertion of the occlusal interference increased the velocity of mandibular rotation around the antero-posterior axis (Roll angle). In addition, the interference increased the variation of the movement of the condylar surface along the meiolateral direction.Conclusions :The results suggested that the interaption of the occlusal balancing contact may cause the derangement of the TMJ.

目的：本研究的目的是探讨人类颞颌关节/咬合方案的不对称性与颞下颌关节负荷之间的生物力学关系。受试者：10 名具有良好咬合的女性受试者参与了本研究。方法：通过 6DOF 运动捕捉系统，同时记录咬合力、咬合面积和 6DOF 下颌运动。在每个受试者中，在习惯咀嚼侧的磨牙咬合面插入或不插入人工咬合干扰物的情况下进行咀嚼口香糖。结果：咬合干扰物的插入增加了下颌绕前后轴旋转的速度（滚动角）。此外，干扰还增加了髁突面沿近外侧方向运动的变化。结论：结果表明，咬合平衡接触的相互作用可能导致颞下颌关节紊乱。
