摩擦力是影响正畸牙滑动效率的主要机械因素,是正畸力学研究的热点之一。笔者就滑动机制下正畸牙移动中摩擦力的力学基础、变化特点及其影响因素的相关研究进行综述。
Friction is the main mechanical factor that affects the sliding efficiency of orthodontic tooth, which is one of the hot spots in orthodontic mechanics research. The author summarizes the mechanics basis, changing characteristics and influencing factors of the friction in orthodontic tooth movement under sliding mechanism.
