Result: To set loads or constraints on the occlusal surface have significant different on the results, but the loads or constraints set on the masseter muscle attachment area have not. 结果:对牙列咬合面进行加载还是进行约束其结果差异较大,而咬肌附丽处进行加载还是进行约束其结果无差异。
CONCLUSION: In complete dentition, the occlusal strength is distributed through the contact area between interproximal teeth, therefore, the stress value of crown is low. 结论:完整牙列受力时,牙合力通过牙之间的接触区传递分散,牙冠的应力值很小。
T-scan ⅱ system was used to determine the occlusal contact area. 用T-扫描系统测定牙合接触面积;
Correlation between the masticatory efficiency and the occlusal contact area was analyzed by SPSS software package. 用SPSS统计软件对咀嚼效能与牙合接触面积之间的关系作相关性分析。
