目的：探讨异常牙合面形态对上颌全口义齿基托应力分布状况的影响。
Objective:To investigate the influence of occlusal surface morphology on stress distribution in the base of maxillary complete dentures(MCD).
目的分析下颌全口义齿软衬前后的义齿基托组织面位移情况，研究其对义齿稳定性的影响。
Objective To study the stability of mandibular complete denture with soft denture liner by means of investigating the displacement of tissue surface of the base plate.
结果有软衬基托组织面位移大于无软衬时义齿组织面位移（P<0.01）；
Results The displacement of the tissue surface of base plate with soft denture liner was significantly larger than that of without soft tissue liner (P<0.01).
