摘　　要：目的研究快速准确建立包含TM(tension more)种植体颌骨三维有限元模型的方法,为种植修复的生物力学分析打下基础。方法通过逆向工程技术,将二维下颌骨CT图片应用Mimics软件转化为三维实体模型,并建立包含TM种植体的真实下颌骨B/2类骨质(皮质骨和松质骨含量相当)的有限元模型。结果快速准确地建立了包含TM种植体的颌骨有限元模型。结论 CT技术、医学数字图像通信标准(digital imaging and communi-cations in medicine,DICOM)的应用使有限元模型的建立更为精确,Mimics软件直接建立三维模型后通过逆向工程技术,直接导入Geo magic Studio 9.0软件提高了建模的效率。Objective To explore a faster and more precise method for establishment of the three-dimensional（3D） finite element model of mandible contained TM implant.Methods Three-dimensional physical model of mandible was established from two-dimensional CT databases with the reverse engineering technology.Based on TM implants with different conical degrees,two different finite element models consisting of corresponding implants and true models of bone in B/2 type were obtained.Results The 3D finite element model of mandible contained TM implant was established.Dicom standard and Mimics software were used to identify the CT images and to write the digital data to Ansys software directly which increased the efficiency of establishment of 3D finite element model.Conclusion A more precise and more faster 3D finite element model of mandible contained TM implant is established,and DICOM standard and Mimics,Geo magic Studio 9.0 software ware can improve the efficiency of establishment of the 3D finite element model.
