(2)关节软骨内部的应力缓冲体系。
(3)关节润滑与滑液、软骨的结构和力学性能、运动状态有关。
(2)粘弹性体:
1)弹性:物体在变形后恢复到变形前的形状和尺寸的能力。
2)粘性:加载时阻滞物体变形、卸载时阻滞物体恢复原有形态的能力。
2.复习颞下颌关节的解剖特征
(!)组成:下颌骨髁状突、颞骨关节面、关节盘、关节囊、关节韧带。
(2)与TMJ内部结构运动协调密切相关的肌肉组织。
3.讲解颞下颌关节咀嚼和张闭口运动时的生物力学

方法、手段、时间
1.生物力学相关概念及简介
(1)生物力学(Biomechanics)是研究生物与力学有关的问题,试图从力学的角度了解和解释生命科学。
4thsection:Classification of occlusion
1)Classification based on morphology
2)Classification based on function
3)Classification based on clinic
PPT
presentation
(4)关节软骨具有承载、应力分散、应力缓冲、关节润滑的功能。
5.讲解颞下颌关节关节盘生物力学
粘弹性材料(类似关节软骨),低渗透性、压缩刚度高。
6.讲解颞下颌关节关节韧带、关节囊生物力学
(1)韧带---粗大胶原纤维,抗牵张能力强---承载较强的拉伸载荷。
(2)囊---细小胶原纤维,组织延展变形性大---适应多向拉伸载荷、利于力的分散、关节滑液的产生、运输。
3rdsection:Biomechanicsof occlusion
1)The bearing properties of occlusal surfaces of posterior teeth
2)The influence of occlusal morphology on the bearing properties
