| 摘 要： | 目的建立腭骨三维有限元模型,为进一步研究腭部种植支抗进行上颌扩大的可行性及其与牙支抗的对比研究建立数学模型基础。方法采用螺旋CT断层扫描成年人上颌骨,计算机图像处理和转录技术,自编程序和ANSYS软件相结合,将CT扫描图像转换为可用于有限元建模的数值图像。结果建立了上颌腭骨、部分颧弓根部的三维有限元模型。结论借助螺旋CT扫描技术和ANSYS有限元分析软件,建立上颌腭骨的有限元模型是切实可行的。该模型为上颌腭部种植支抗的生物力学研究提供了一个平台。

| Abstract: | Objectives To construct a three-dimensional finite element model of palate for the further investigation of palatal implant anchorage for RME in adults and the comparison between the tooth-borne RME and the bone-borne one.Methods Spiral CT scanning,several image processing softwares and ANSYS were employed to create the three dimensional finite element model.Results A three dimensional finite element model of palate is successfully created,meeting the requirements of further biomechanical research.Conclusion It is feasible to construct the three dimensional finite element model of palatal implants in palate by using Spiral CT scan technique and ANSYS software.This model provides a foundation for the study of palatal implants' biomechanics in RME of adults. |
