摘要
目的:探讨运用CAD软件模拟制作有限元义齿模型,为简化有限元建模提供一种方法。方法:在CT扫描方法建立的下颌骨及基牙牙根的三维有限元基础模型上,用CAD软件在计算机上分别模拟套筒冠及“O”型圈附着体两种覆盖义齿制作。结果:建立了“O”型圈附着体义齿与套筒冠义齿的三维有限元模型。结论:运用CAD软件在计算机上直接制作有限元义齿模型,方便可行,可以为临床上修复体优化设计提供实验基础。
Objective: To establish the method of finite element denture model construction aided by CAD software. Methods: Attachments, denture base and artificial tooth were simulated in computer by CAD software. Results: Digital telescopic overdenture and O-ring coping attachmets overdenture were constructed in computer. Conclusion: The method of using CAD software to make finite element model of overdenture in computer is feasible and the model provides the basis for optimization of prostheses design.
