摘要/Abstract

摘要： 目的：比较不同抛光方式和时间处理上颌前磨牙预备体对CAD/CAM氧化锆全瓷冠适合性的影响。方法：选择离体上颌前磨牙16颗,随机分为A组（金刚砂车针组）和B组（钨钢抛光车针组）。2组分别在同一基牙的不同抛光时间节点获取数字化印模,制作CAD/CAM氧化锆全瓷冠。试戴完成后,采用硅橡胶复制法获取间隙印模,在体视显微镜下测量边缘间隙及内间隙。采用SPSS 21.0软件包对数据进行统计学分析。结果：A组边缘及内部各标志点的间隙值与B组相比无显著差异（P>0.05）。A组抛光4 min的边缘间隙为（39.67±8.35） μm,内部间隙为（45.18±7.16） μm;B组抛光3、4 min的边缘间隙分别为（51.25±14.73） μm和（48.87±8.90） μm,内部间隙分别为（48.56±6.45） μm和（45.99±7.12） μm;与不抛光组相比,均有显著差异（P<0.05）。结论：采用金刚砂车针抛光4 min、钨钢车针抛光3 min制作的CAD/CAM全瓷冠适合性最好。

Abstract: PURPOSE: To compare the effect of different polishing methods and time treatment on the fitness of CAD/CAM zirconia ceramic crowns. METHODS: Sixteen intact maxillary premolars were randomly divided into two groups, group A was treated with silicon carbide burs, while group B was treated with tungsten steel burs. At different polishing time points of the same tooth, digital impressions of each group were obtained, which were used to manufacture CAD/CAM zirconium ceramic crowns. After trial fitting, the gap impressions were obtained by using silicone rubber replication method, and the marginal and internal discrepancies were assessed. The data were statistically analyzed with SPSS 21.0 software package. RESULTS: The difference between the gap values of the marginal and internal markers of group A and group B was not statistically significant(P>0.05). Compared with the no-polishing process, the differences of the marginal gap (39.67±8.35) μm and internal gap (45.18±7.16) μm of group A polished for 4 min, and the marginal gap (51.25±14.73) μm, and internal gap (48.56±6.45) μm of group B polished for 3 min, as well as the marginal gap (48.87±8.90) μm, and internal gap (45.99±7.12) μm of group B polished for 4 min, were all significant(P<0.05). CONCLUSIONS: CAD/CAM zirconia ceramic crowns treated with silicon carbide bur for polishing 4 min and tungsten steel for 3 min has the best fitness.
