| 摘 要： | 目的:利用ABAQUS软件,应用有限元方法对牙齿咬合进行仿真,并建立咬合接触关系的评测方法,以辅助医生制定正颌外科手术方案。方法:运用Mimics软件重建上下颌骨的三维几何模型,并在该模型的基础上对关节盘模型进行了简化,建立了上下颌骨的有限元模型,通过ABAQUS软件对咬合进行仿真计算。结果:通过对牙尖交错位进行咬合分析,得到牙齿表面上的应力分布云图,应用图像处理方法将应力区域分布转化成咬合点的形式,建立了用于评价咬合接触关系的评测方法。结论:该方法根据咬合点的情况判断手术后的咬合接触效果,可对正颌外科手术的术后咬合接触关系进行术前评测,并通过仿真结果辅助手术方案的完善,从而提高手术效果。
