| 摘 要： | 目的建立正常人下颌升支矢状截骨术(bilateral sagittal split ramus osteotomy,BSSRO)的三维有限元模型,为该术式的生物力学研究和分析奠定基础。方法选牙列完整、牙合关系正常的成年男性,经CT扫描后,采用坐标数据化法,利用专业有限元软件建立包括关节盘的下颌骨三维有限元模型(three dimension finite element model,3D-FEM),并在计算机上模拟改良BSSRO术进行截骨。结果获得的三维有限元模型图形逼真,并且在功能状态中的力学改变与体外力学实验得出的数据吻合程度高。结论利用有限元软件采用CT图形坐标数据化法可建立仿真程度较高的BSSRO模型。 |

| Abstract: | Objective To built a 3D-finite element model(FEM) of mandible bilateral sagittal split ramus osteotomy(BSSRO).Methods Mandible CT scan pictures of were taken with a adult man with normal dentition and occlusion,and a 3D-FEM was then established with professional software.With the same soft ware,we simulated BSSRO operation and various fixation patterns.Results A vivid 3D-FEM was made and it possessed the same mechanical character under mechanics experiment.Conclusion By means of professional soft ware and C... |
