摘要：

背景：双侧升支矢状劈开截骨术是正颌外科常见的治疗方法之一，有限元法成为研究双侧升支矢状劈开内固定后生物力学的重要方法。
目的：快速建立下颌骨双侧矢装劈开内固定后有限元模型，寻求一种更为快捷、精确的矢装劈开内固定的三维有限元模型，为研究下颌骨矢装劈开内固定后生物力学打下基础。
方法：应用薄层CT ,Dicom 标准和Mimics 软件,结合MSC.Patran 三维有限元专用软件对CT 断层影像进行分析处理。
结果与结论：建立了精确的下颌骨双侧矢装劈开内固定后三维有限元模型。使用Dicom 标准和Mimics 软件获取三维模型，直接写入MSC.Patran 三维有限元软件,提高了建模效率。提示薄层CT、Dicom 标准的应用使得有限元模型的建立更为精确，同时Mimics 软件直接建立矢装劈开内固定三维模型，极大程度提高了建模效率，为生物力学分析打下基础。

Abstract:

BACKGROUND: Bilateral-sagitta-split-ramus-osteotomy (BSSRO) is a useful method for orthognathic surgery; finite element method is an important approach in studying BSSRO biomechanics.
OBJECTIVE: To explore an easier and more precise method for establishment of the three-dimensional (3D) finite element model of mandible BSSRO and lays foundation for the research of biomechanics after BSSRO.
METHODS: CT faultage image was analyzed by thin-layer CT, Dicom standard and Mimics software combined with MSC.Patran software.
RESULTS AND CONCLUSION: A 3D finite element model of mandible BSSRO was established. Dicom standard and Mimics software were used to obtain the CT images and write the digital data to MSC. Patran software directly, which increased the efficiency of establishment of the 3D finite element model. It is indicated that the application of thin-layer CT and Dicom standard make the establishment of finite element model more precise. Meanwhile, BSSRO was directly established by Mimics software, the application of Mimics software can improve the efficiency of establishment of the 3D finite element model to a large extent, and lays foundation for biomechanics analysis.
