目的:比较上颌美学区单牙即刻种植即刻修复和即刻种植延期修复的美学效果.方法:上颌美学区单牙即刻种植病例36例, A组行即刻修复 (17例) , B组行延期修复 (19例) , 所有病例均使用临时基台和临时树脂修复体进行牙龈诱导, 6个月后开始永久修复, 使用红白美学指数进行评分.统计分析两组病例得分.结果:36枚种植体均获得良好的骨结合并完成种植修复, 种植体留存率100％.A组红色美学指数得分 (PES) (11.45±1.77) 高于B组 (11.26±1.48) , 差别无统计学意义 (P=0.77>0.01) .A组白色美学指数得分 (WES) (8.36±1.23) 低于B组 (8.38±1.25) , 差别无统计学意义 (P=0.87>0.01) .A组中PES≥12的病例数为8 (47.06％) , B组中PES≥12的病例数为9 (47.37％) , 差别无统计学意义 (P=1.64>0.01) .A组中WES≥9的病例数为9 (52.94％) , B组中10例病例WES≥9 (52.63％) , 差别无统计学意义 (P=0.55>0.01) .结论:随访12个月, 上颌美学区单牙即刻种植即刻修复和即刻种植延期修复的美学效果无统计学差异, 两组种植体留存率也无统计学差异.%Objective: To compare the esthetic outcome between single implant-supported immediate restoration and delayed restoration following immediate implant treatment in the anterior maxillary.Methods: Thirty-six single implants were included. All of the implants were placed immediately into fresh extractions. 17 implants received immediate provisional restorations (Group A) and 19 implants executed delayed provisional restorations (Group B) which based on temporary abutments and temporary crowns. The final restorations were performed after 6 months and assessed using pink esthetic scores (PES) and white esthetic scores (WES). Results: All of the implants gained osseointegration. The survival rate of both groups were 100％. There was no significant difference between two groups. Mean value of PES in Group A (11.45±1.77) was higher than that of Group B (11.26±1.48) , mean value of WES in Group A (8.36±1.23) was lower than that of Group B (8.38±1.25) , there was no statistically significant difference between two groups. 47.06％ of Group A showed perfect pink esthetic outcome (PES ≥12) , 47.37％ in Group B. About white esthetic outcome (WES≥9) , 52.94％ in Group A and 52.63％ in Group B, these values showed no statistically significant difference between two groups. Conclusion: In the 12 months follow-up period, there are no statistically significant difference between two groups both in esthetic outcomes and implant survival rate.
