摘要
为研究在不同咬合方式和不同咬合力下颌骨的受力情况,基于已有的头部CT数据,通过医疗软件Mimics提取下颌骨并建立三维模型,并对下颌骨进行重画网格、构造轮廓线、构造曲面片、构造格栅、拟合曲面等分析.通过对正常的下颌骨以及3D打印钛合金植入物修复的下颌骨进行对比分析.研究在不同咬合方式和不同咬合力的情况下,下颌骨的受力情况,分别得到下颌骨不同部位加载下的应力和位移分布情况.结果表明,在3D打印钛合金植入物修复的下颌骨上加载成年男性前,后牙所能承受的最大咬合力时,下颌骨所受到的应力均小于正常下颌骨所受到的应力.
In order to study the stress of the mandible under different occlusal methods and different bite forces,based on the existing head CT data,the mandible was extracted through the medical software Mimics and the threedimensional model was established,and the mandible was analyzed by redrawing the mesh,constructing the contour line,constructing the curved surface,constructing the grille,and fitting the surface.Through to the normal mandible and 3 d printing titanium implant restoration of mandibular were analyzed,and the results show that:in the 3 d printing on the titanium alloy implant restoration of mandibular adult male before and after loading teeth can withstand maximum force,mandibular by stress are less than normal mandible by stress.
