:目的 构建无牙颌包括下颌骨的颞下颌关节( TMJ) 三维有限元模型;探讨戴用全口义齿无牙颌患者在牙尖交错位 紧咬牙时颞下颌关节髁状突的应力分布特征。方法 以活体人颅为标本,采用螺旋CT 断层扫描技术,图像数字化处理 等方法在计算机上构建模型,然后在载荷状态下,利用ANSYSV8. 0 软件进行运算分析。结果 建立了无牙颌下颌骨和 颞下颌关节三维有限元模型,并在此模型后牙相应位点加载、运算、分析显示:髁突近颈部应力力值明显大于近顶区;前、 后斜面由外向内力值逐渐减小;外、内侧由前向后力值逐渐减小,前斜面、外侧上1/ 2 (近髁突顶) 区域压应力占主导地 位,下1/ 2 (近颈区) 区域以拉应力为主,下外侧为主要应力集中区;后斜面及内侧上1/ 2 以拉应力为主,下1/ 2 以压应力 为主。结论...
