摘　　要：目的:探讨CEREC不同设计模式制作的瓷贴面在前牙修复中的应用价值。方法:回顾性分析76例患者的临床资料,采用CEREC AC系统共制作瓷贴面190个,根据患者前牙缺损实际情况选择合适的设计模式。比较不同设计模式的修复体设计与加工时间、随访6个月、12个月、24个月的患者修复体满意度与临床成功率。结果:所有190个瓷贴面中,84个采用复制模式、50个采用参考模式、56个采用个性化设计模式。复制模式的修复体设计与加工时间短于参考模式与个性化模式(P<0.001),参考模式短于个性化模式(P<0.001)。不同设计模式不同随访时间的修复满意度评分比较差异无统计学意义(P>0.05)。随访6个月,复制模式、参考模式、个性化模式的成功率分别为97.62%、98.00%、94.64%,随访12个月的成功率分别为97.62%、96.00%、92.86%,随访24个月的成功率分别为96.43%、94.00%、92.86%,差异无统计学意义(P>0.05)。结论:CEREC AC系统不同设计模式制作的全瓷贴面均具有良好的美学效果与较高的临床成功率,其中复制模式可精确复制咬合,且设计与加工时间相对更短,可作为首选。Objective:To explore the application of veneer made by CEREC with different design patterns in the anterior area.Methods:The clinical data of 76 patients who underwent anterior veneer restoration were retrospectively analyzed.190 veneers were made using CEREC AC system.Different design modes were chosen according to actual situation of the tooth defect.The design pattern,processing time,patients’satisfaction degree,and clinical success rate after 6 months,12 months,and 24 months were compared.Results:Of all the 190 porcelain veneers,84 use copy mode,50 use reference mode,and 56 use individual design patterns.The restoration design and processing time of the replication mode was shorter than the reference mode and the personalized mode(P<0.001),and the reference mode was shorter than the personalized mode(P<0.001).There was no significant difference in the satisfaction scores of VAS repair between different design patterns at different follow-up time(P>0.05).After 6 months,the success rates of replication mode,reference mode,and personalized mode were 97.62%,98.00%,and 94.64%,respectively.The success rates after 12 months were 97.62%,96.00%,and 92.86%,respectively.The success rates after 24 months were 96.43%,94.00%,and 92.86%,respectively(P>0.05).Conclusion:All the porcelain veneers made by different design modes of CEREC AC system have good aesthetic effect and high clinical success rate.The copy mode can accurately copy the bite,and the design and processing time are relatively shorter,which can be used as the first choice.
