摘　　要：目的:比较计算机辅助设计与计算机辅助制作(CAD-CAM)氧化锆全瓷冠与金属烤瓷种植体牙冠的修复效果和临床性能。方法:选取2021年1月—2023年1月江门市新会区新会第二人民医院收治的100例全冠单冠修复患者,按随机数字表法分为A组(n=50)与B组(n=50)。A组行金属烤瓷种植体牙冠修复,B组行CAD-CAM氧化锆全瓷冠修复,比较两组患者修复效果及并发症发生情况,比较两组患者修复前、修复后6个月牙周袋深度(PD)、附着丧失(AL)、龈沟出血指数(SBI)、牙龈指数(GI)水平。结果:B组患者牙冠修复总有效率高于A组,差异有统计学意义(P<0.05)。修复前,两组患者PD水平、AL水平、GI评分、SBI评分比较,差异无统计学意义(P>0.05);修复后6个月,B组患者PD水平、AL水平、GI评分、SBI评分均低于A组,差异有统计学意义(P<0.05)。B组患者牙冠修复并发症总发生率低于A组,差异有统计学意义(P<0.05)。结论:CAD-CAM氧化锆全瓷冠对全冠单冠修复效果好于金属烤瓷种植体牙冠的修复,可降低并发症发生率,帮助患者改善牙周健康问题。Objective To compare the restorative effect and clinical efficacy of computer-aided design and computer-aided fabrication(CAD-CAM)of zirconia all-ceramic crowns with that of metal-porcelain implant crowns.Methods A total of 100 patients who underwent single crown crown restoration in Xinhui Second People's Hospital of Xinhui District,Jiangmen City from January 2021 to January 2023 were selected and randomly divided into Group A(n=50)and Group B(n=50)using a random number table method.Group A underwent metal ceramic implant crown restoration,while Group B underwent CAD-CAM zirconia all ceramic crown restoration.The restoration effect and incidence of complications were compared between the two groups.The periodontal pocket depth(PD),attachment loss(AL),gingival sulcus bleeding index(SBI),and gingival index(GI)levels before and 6 months after restoration were compared between the two groups.Results The total effective rate of crown restoration in Group B patients was higher than that in Group A,and the difference was statistically significant(P<0.05).Before repair,there was no statistically significant difference in PD level,AL level,GI score,and SBI score between the two groups of patients(P>0.05).After 6 months of repair,the PD level,AL level,GI score,and SBI score of Group B patients were lower than those of Group A,and the differences were statistically significant(P<0.05).The incidence of complications in crown repair in Group B patients was lower than that in Group A,and the difference was statistically significant(P<0.05).Conclusions The CAD-CAM zirconia all ceramic crown has a better restoration effect on a single crown than on a metal ceramic implant crown,can reduce the incidence of complications,help patients improve periodontal health problems.
