| 摘 要： | 目的建立三种不同腭穹隆形态及牙尖斜度的上颌全口义齿及其下支持组织的三维有限元模型。方法根据三维坐标测量数据,在计算机上采用MATLAB6.1和ALGORFEAS软件建立三维有限元模型。结果得到尖、平、凹三种不同腭穹隆形态,牙尖斜度分别为0°、20°、30°的上颌全口义齿及其支持组织的三维有限元模型。结论该模型的建立为在不同加载方式下三种腭穹隆形态及牙尖斜度的上颌全口义齿基托及其下支持组织的应力分析奠定基础。

| Abstract: | Objective To construct three-dimensional finite element model (3-D FEM) of maxillary complete denture and its supporting tissues with different shapes of palatal vault and different teeth cusp inclination. Methods Based on the data of 3-D measurement, using MATLAB 6.1 and ALGOR FEAS software, 3-D FEM was constructed by computer. Results 3-D FEM of maxillary complete denture was constructed with three different palatal vault and three different teeth cusp inclination (10°, 20°, 30°) and supporting tissues. Conclusion 3-D FEM can be used for the analysis of the effect of different shapes of palatal vault and different teeth cusp inclination on the stress distribution of maxillary complete denture under different loading conditions. |
