摘要： 目的:比较3种CAD/CAM个性化种植体基台(一段式氧化锆基台、两段式氧化锆基台和一段式钛基台)与种植体替代体界面内部连接的适合性。方法:3SHAPE软件设计CAD/CAM个性化基台,数据导入计算机控制的切削系统,切削加工一段式氧化锆基台、两段式氧化锆基台和一段式钛基台(N=15);将基台与NobelActiveTM种植体替代体连接,应用体视显微镜测量种植体替代体-基台界面边缘微间隙,统计分析数据结果。结果:一段式氧化锆组的边缘间隙最大,两段式氧化锆组的边缘间隙次之,最小的为一段式钛基台组;各组之间唇侧、舌侧、近中侧、远中侧的边缘间隙值没有统计学差异。结论:一段式钛基台具有最优的种植体-基台界面密合性。

Abstract: Objective: To compare the marginal fitness of three types of CAD/CAM customized implant abutments (one-piece zirconia abutments, two-piece zirconia abutments and one-piece titanium abutments) between the implant-abutment interfaces. Methods: 3SHAPE software was used to design the customized CAD/CAM abutments. Three types of implants including one-piece zirconia abutments, two-piece zirconia abutments, and one-piece titanium abutment were fabricated after importing the designed data into computer-controlled cutting system (n=15). Stereomicroscope was used to measure the micro-gap of the implant-abutment interface. The results of the gap value were analyzed using statistical method. Results: The titanium abutment showed the lowest gap values, and those of the two-piece zirconia abutments were lower than those of the one-piece zirconia abutments. There was no statistical difference on the gap values among the palatal, labial, mesial, and distal surfaces in the same type of abutment. Conclusion: The one-piece titanium abutment showed the best marginal fit.
