摘　　要：目的建立下颌磨牙种植修复体的三维实体和有限元模型,为种植体周围骨的应力分析研究提供模型支持。方法利用CT薄层扫描技术和UG软件的实体建模技术,结合PATRAN有限元分析软件建立不同设计方式种植修复下颌第一磨牙的三维实体和有限元模型。结果快捷、精确地在计算机上建立了单种植体和双种植体方式修复下颌第一磨牙的三维实体和有限元模型,建立的模型可进行准确的力学分析。结论采用CT扫描,辅助UG建模技术,结合Patran软件建立含种植体的牙颌模型,可提高模型的仿真性和建模的高效性。Objective To establish a three dimensional solid and finite element model of implant-supported mandibular first molar with crown for biomechanical research. Methods The model was constructed by means of SCT scanning technology, UG engineering design program, and MSC Patran software. Results The three-dimensional solid and finite element model of single and dual implant-supported mandibular first molar with crowns were set up accurately and quickly, which could be used for biomechanical analyse. Conclusion The procedure of building models of tooth, implant, and mandible is available to improve model similarity and efficiency .
