摘　　要：目的:建立下颌第一磨牙半切术的三维有限元模型。方法:薄层CT扫描,联合应用CAD软件AMIRA和UnigraphicsNX建立三维几何模型,然后导入有限元分析软件ALGOR软件中生成实体模型。结果:所构建的三维有限元模型具有良好的几何相似性,共有单元47155个,节点数41878个,可以按照不同的研究要求进行删除、旋转、切割和添加。结论:所构建的下颌第一磨牙半切术的三维有限元模型结构完整,单元划分精细的优点,能够较精确地模拟实体状态,为进一步的生物力学研究打下基础。Objective To construct a three-dimensional finite element analysis model of the first mandibular molar with hemisection prosthodontic therapy. Methods After the CT Scanning and image processing, a 3-D geometric model was established by the combination of the AMIRA and Unigraphics NX, the CAD software. The mesh model was then built in ALGOR, the finite element analysis software. Results The three dimensional finite element model was constructed on the computer, which had 47 155 nodes and 41 878 tetrahedrons elements. Conclusion The finite element model constructed has the advantages of intact structure and precise elements,can simulate the natural condition and facilitate the further biomechanical research.
