[摘要]有限元分析法应用于口腔研究首先需要建立计算机口腔模型，目前的文献对建模的过程没有做详细的阐述。本文运用高端的建模与分析软件，以建立一个牙齿计算机模型为例，阐述一种高效建立有限元分析模型的基本思路和方法，为从事医学有限元分析法相关研究的科研人员提供参考。

    [Abstract]The construction of a dental model is a prerequisite for finite element method(FEM)analysis in orthodontics, however so far no research has focused on the detailed discussion of the modeling process. This study adopted the higher level modeling and finite element analysis software package to construct one tooth model with higher efficiency and precision, and intended to demonstrate the basic rationale of a FEM modeling process. It is expected this study be a guide for the researchers in this field. ......
