摘　　要：目的比较不同品牌的CAD/CAM氧化锆个性化基台与钛基之间的适合性。方法用CAD/CAM分别设计和加工3种氧化锆个性化基台(日进、爱尔创和卡瓦),每种5个。通过扫描电子显微镜,测量氧化锆个性化基台与钛基之间的边缘间隙(MG),比较3种氧化锆个性化基台与钛基之间的边缘适合性。结果卡瓦组(7.19±2.98)μm与日进组(10.25±6.25)μm和爱尔创组(9.87±5.48)μm的边缘间隙的差异具有统计学意义(P<0.05);爱尔创组与日进组的边缘间隙的差异无统计学意义(P>0.05)。结论不同的材料直接影响个性化基台与钛基之间的适合性。在个性化基台与钛基的边缘适合性方面,卡瓦氧化锆明显优于日进及爱尔创氧化锆。Objective To compare the marginal fit between CAD/CAM zirconia custom abutments of different brands and Ti-base. Methods CAD/CAM system was used to fabricate three groups （KaVo, Nissin and Upcera） of zirconia custom abutments and each with five samples. The marginal gap （MG） was evaluated by scanning electron microscope （SEM） for comparing the marginal fit. Results The mean MG value was （10.25±6.25） μm in Nissin group and （9.87±5.48） μm in Upcera group, which were significantly different from （7.19±2.98） μm in KaVo group （P〈0.05）. No significant differences were observed between the mean MG values in Nissin and Upcera groups （P〉0.05）. Conclusion Different CAD/CAM materials directly affect the fit between custom abutments and titanium base. As for the marginal fit, KaVo is much better than Nissin or Upcera.
