摘　　要：目的:建立人下颌D区567三维有限元模型.方法:采用薄层CT扫描技术、医学影像三维重建软件Amira和Unigraphics NX造型软件以及有限元分析软件ALGOR相结合建立下颌567及其支持组织的三维有限元模型.结果:建立了下颌D区567三维有限元模型,总节点为93260个,六面单元数为167111个.结论:所建模型结构完整,空间结构测量准确度高,单元划分精细、能够较精确地模拟实体状态,为进一步的生物力学研究提供了基础.AIM： To construct a three dimensional （3D） finite element model of human mandibular molars. METHODS： Thinsection CT scanning technology was used in combination with medical image reconstruction software Amira4. 0, Unigraphics NX, the finite element analysis software ALGOR to construct a 3D finite element model of mandibular molars （5, 6, 7 ） and their supporting tissues. RESULTS：The 3D finite element models of the mandibular molars （5, 6, 7 ） was constructed, including 93, 260 nodes and 167,111 elements. CONCLUSION： The constructed model has the advantages of intact structure, precise elements, high measure accuracy, and can simulate the natural condition and facilitate the further biomechanical research.
