| 摘 要： | 目的 探讨采用附着体修复单侧上颌骨缺损的可行性.方法 在已完成的环氧树脂单侧上颌骨缺损牙颌模型上,分别制作传统卡环修复体和附着体修复体.采用光弹应力分析法,对两种修复体在载荷条件下的应力分布情况进行分析和比较.结果 传统卡环修复体与附着体修复体在腭部应力分布无明显差异,健侧后牙受力均匀;与传统卡环修复体比较,附着体修复的中切牙近中牙槽嵴应力条纹级数相对较高.结论 附着体修复体健侧后牙的应力分布均匀,符合生物力学要求;其对于中切牙和中切牙近中牙槽嵴应力较集中,可通过增加基牙数目的 联冠设计提高支持作用和对抗转动扭转力.

| Abstract: | Objective To explore the feasibility of prosthesis with attachment for unilateral maxillary defect.Methods The unilateral maxillary defect models with traditional clasp and attachment were prepared respectively.Photoelastic analysis was conducted to compare the stress distribution with load between the two restorations.Results There was no significant difference in stress distribution in palate between restoration with traditional clasp and that with attachment,and the stress was well distributed on the pos... |
