Effect of depth and angle of reverse-curve arch wires on stress distribution of tooth roots and periodontal tissue
摇椅弓角度和弧形深度对牙根和牙周组织应力分布的影响
Objective: With the method of 3-D finite element analysis, the study was to analyze the perpendicular force on each tooth as well as the Von Mises distribution on tooth roots, periodontal ligaments and alveolar bone that were produced by the reverse-curve arch wires of various angles and depths.
目的:通过三维有限元法分析摇椅弓角度和弧形深度的变化对前后牙垂直向力以及牙根和牙周组织第四强度Von Mises综合应力分布的影响。
