摘　　要：目的:快速准确建立患者下颌无牙颌三维有限元模型,为种植修复的生物力学分析打下基础。方法:CT扫描患者下颌骨,转换为DICOM数据后用Mimics软件重建三维图像,再用自编命令流导入Ansys软件进行分析处理。结果:快速准确地建立了活体下颌无牙颌三维有限元模型。结论:CT技术,DICOM标准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直接导入Ansys软件极大的提高了建模效率。Objective： To explore an faster and more precise method for establishment of the three -dimensional （3 D） finite element model of edentulous mandible. Methods ： A edentulous mandible was scanned by CT and the CT images were analyzed and managed with Dicom standard and Mimics software. At the same time, the CT images were analyzed with Ansys software. Results： The 3D finite element model of mandible was established. Dicom standard and Mimics software were used to identify the CT images and 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 is established, and Dicom standard and Mimics software can improve the efficiency of establishment of the 3D finite element model.
