本研究的目的是建立有限元(FE)模型来模拟治疗期间(4周)有龋齿负荷的下颌尖牙正畸治疗的身体运动。牙周膜的正常应变被认为是表面骨重塑的关键力学刺激。在模拟过程中，考虑了牙齿位置、牙齿支撑结构几何形状和衰减载荷的变化。在此数值模拟中，牙齿在治疗结束时的移动位移为1.00 mm。模拟的结果与临床研究中观察到的结果相似。基于这些力学假设，用有限元方法模拟临床牙齿移动是可以接受的。这样的数值模拟将有助于了解牙齿的移动情况，并有助于更好地规划个人策略。版权所有©2008 John Wiley&Sons，Ltd.
The aim of this study was to develop finite element (FE) models to simulate bodily movement of an orthodontic treatment of mandibular canine with decayed loads during a therapy period (4 weeks). The normal strain of periodontal ligament was assumed as the key mechanical stimulus for the surface bone remodeling. During the simulation processes, changes in tooth position and in the geometry of the tooth supporting structures and the decayed loads were taken into account. In this numerical simulation, the tooth movement displacements were 1.00 mm in the end of the therapy. The results of the simulation were similar to the observed in clinical studies. It was acceptable to simulate clinical tooth movements by FE method based on these mechanical assumptions. Such a numerical simulation would allow the understanding of tooth movements and help in better planning of individual strategies. Copyright © 2008 John Wiley & Sons, Ltd.
