摘要： 目的:比较粘固固位种植全冠牙合面、舌面粘固剂溢出孔和基台穿龈区包裹聚四氟乙烯薄膜对龈沟内多余粘固剂量的影响。方法:下颌后牙种植义齿模型24个,分别使用种植全冠牙合面开孔(A组)、舌面开孔(B组)、基台穿龈区包裹聚四氟乙烯薄膜(C组)及常规粘固(D组)4种方法粘固牙冠(n=6),收集龈下粘固剂,电子天平称重(mg)。对所得结果行单因素方差分析。结果:A、C两组的粘固剂质量均小于B、D两组,差异具有统计学意义(P＜0.05);A、C两组间及B、D两组间相比,差异无统计学意义(P＞0.05)。结论:相比于种植全冠舌面开孔粘固和常规粘固,牙合面开孔及聚四氟乙烯薄膜包裹基台穿龈区可减少龈下多余粘固剂的量。

Abstract: Objective: To observe the effect of treatment methods on the subgingival excessive cement of cement-retained implant crowns. Methods: 24 die stone models of mandibular posterior denture with bone level implant were used to cement crowns by four methods, namely, cement venting hole on the occlusal (group A), on the lingual surface (group B), isolation of PTFE on subgingival region of abutments (group C), and routine cementation (group D)(n=6). To collect the subgingival residual cement, the weigh was measured by electronic balance (mg). Analysis of one-way ANOVA was conducted with SPSS 17.0 (α=0.05). Results: The weight of subgingival excessive cement in group A and group C were less than those in group B and group D (P<0.05). Neither significant difference between group A and group C nor between group B and group D was observed (P>0.05). Conclusion: Compared with the cement venting hole on the lingual side and conventional bonding method, cement venting hole on the occlusal surface and the use of PTFE membrane to isolate the surface of abutment through the subgingival area during bonding can reduce the subgingival excessive cement effectively.
