1·AIM: to study the stress distribution of periodontal membrane of fixed abutment tooth with different thickness, and provide theoretical basis in clinic.
目的：研究固定桥基牙牙周膜厚度不同时牙周膜内的应力分布，为临床工作提供理论依据。
2·Without the protection of periodontal membrane, we should pay more attention to the occlusion design, controlling the value and direction of occlusal force exerted on DE.
该结构缺乏牙周膜组织，故应通过咬合设计控制种植义齿咬合力大小及方向对种植体加以保护。
3·Stress distribution of periodontal membrane loaded with the same vertical and horizontal forces was analyzed during different thickness of periodontal membranes around abutments.
在相同垂直载荷和水平载荷情况下，分析固定桥基牙牙周膜厚度不同时牙周膜内的应力分布。
4·Objective: to investigate the biocompatibility of chitosan as membrane for periodontal guided tissue regeneration (GTR).
目的：观察壳聚糖作为牙周引导组织再生膜的生物相容性。
5·Objective To study the histological change in rabbits and clinical effect by using artificial membrane to repair the periodontal defect bone tissue.
目的观察人工合成组织再生膜修复动物牙周骨缺损的组织学变化及临床疗效。
6·CONCLUSION: Both of sintered bone and lyophilized collagen membrane are expected to be the materials for scaffolds in periodontal tissue engineering.
结论：煅烧骨和冻干胶原膜均有望成为牙周组织工程支架材料。
7·Results: Making use of this new method, a new periodontal tissue regeneration membrane with higher mechanical strength can be prepared.
结果：电纺技术制备出具有一定力学强度的缓释微球的纤维膜。
8·Objective: To observe the effect of bianticollagen membrane in guiding periodontal tissue regeneration.
目的：观察双抗胶原膜（BACM）引导周组织再生的疗效。
