摘要 目的:探讨建立牙颌组织个体化有限元模型库的方法。方法:以正常上下颌骨及全牙列三组有限元模型为基础,利用Ansys5.5分析软件,分割、修整或重建非正常情况的牙颌组织模型。结果:分类建成3类常用的模型库,包括牙槽骨吸收牙、松动牙、以及缺牙区牙槽骨降低3类情况,308个单元体。结论:模型具有良好的几何形态,有限元力学模型用于个体化病例,更符合临床和科研需要。 PURPOSE:To investigate the method of establishing the individual model libraries for stomatognathic system. METHODS: Based on the normal 3D FE models, including the upper jaw, lower jaw and whole dentitions, with the help of the ANSYS5.5, divided, trimmed or re-built these models, created the abnormal stomatognathic system. RESULTS: Established three model libraries in common use, including the alveolar-absorbed-teeth, loosed-teeth, and alveolar-reduced-area, 308 models in all. CONCLUSION: The established models have a satisfied geometric configuration, it will be more suitable for the research and clinic works if uses the individual FE models.
