摘要
目的:探讨上颌骨后牙区、上颌窦、颧骨及颧骨种植体的三维有限元建模方法。方法:采用螺旋CT扫描正常成人颅颌骨,利用3D-Doctor软件进行数据采集,数据导入ABAQUS软件中建立三维有限元模型,并模拟建立颧骨种植体模型。结果:建立的三维有限元模型几何相似性好,在操作平台上可随意观察。结论:采用CT扫描技术及ABAQUS建模技术可以建立切实可行的上颌骨后牙区、上颌窦、颧骨及颧骨种植体的生物力学模型。
ObJective： To explore the method to construct three- dimensional finite element model for maxillary posterior -tooth area, maxillary sinus, zygoma and zygomatic implant. Methods： A young man with normal occlusion was adopted for spiral CT scanned transverse section which was then used to establish the model by 3D -Doctor and ABAQUS computer software. Zygomatic implant was simulated into the model. Results： Geometric similarity of the model was good. The model could be observed optionally. Conclusion： The method to develop three - dimensional finite element model for maxillary posterior - tooth area, maxillary sinus, zygoma and zygomatic implant by spiral CT scanning and ABAQUS software was feasible.
