Abstract

Basic principles of engineering mechanics are used to solve for force vectors in the masticatory system. It was found that incisor guidance/cusp angulation, crown heights and the anterior-posterior location of contact can significantly affect the magnitudes and/or directions of forces acting on contacting teeth and the temporomandibular joint. The results provide insight into the function of the jaws and the diagnosis and treatment of occlusion-related trauma.

摘要

工程力学的基本原理用于求解咀嚼系统中的力矢量。研究发现，切牙引导/牙尖倾斜度、牙冠高度以及接触的前后位置会显著影响作用于接触牙齿和颞下颌关节的力的大小和/或方向。这些结果为颌骨功能以及咬合相关创伤的诊断和治疗提供了见解。
