瓷贴面与烤瓷全冠在口腔美容修复中的效果比较

Comparison of the effects of porcelain veneers and full-porcelain crowns in oral cosmetic restoration

目的比较在口腔美容修复中采用瓷贴面与烤瓷全冠的效果。方法88例接受口腔美容修复的患者,采用随机数字表法分为观察组与对照组,每组44例。观察组患者接受铸瓷贴面修复,对照组接受钴铬烤瓷全冠修复。对比两组修复后1、3、6个月及1年的修复效果评分,修复后即刻、修复后1年牙周健康状况[牙龈出血指数(BI)、牙周袋深度(PD)及附着丧失(AL)],不良事件发生情况。结果修复后1个月,两组患者修复效果评分对比差异无统计学意义(P>0.05);修复后3、6个月及1年,观察组患者的修复效果评分分别为(12.54±0.80)、(11.88±0.50)、(11.00±0.49)分,显著高于对照组的(11.70±0.76)、(10.32±0.45)、(8.84±0.39)分,差异均具有统计学意义(P<0.05)。修复后即刻,两组患者的BI、PD以及AL对比差异无统计学意义(P>0.05);修复后1年,观察组患者的BI、PD以及AL均显著低于对照组,差异具有统计学意义(P<0.05)。随访1年,观察组患者不良事件发生率为4.55%,显著低于对照组的20.45%,差异具有统计学意义(P<0.05)。结论与应用烤瓷全冠修复比较,在口腔美容修复中采用瓷贴面修复效果更佳,牙周健康得到有效保障,临床应用价值更高。

Objective To compare the effects of porcelain veneers and full-porcelain crowns in oral cosmetic restoration.Methods A total of 88 patients who received oral cosmetic repair treatment were randomly divided into observation group and control group,with 44 cases in each group.Patients in the observation group were treated with cast porcelain veneer,and the patients in the control group were treated with cobalt-chromium full-porcelain crowns.Both groups were compared in terms of restorative effect score at 1,3,6 months and 1 year after restoration,periodontal health status[bleeding index(BI),pocket depth(PD)and attachment loss(AL)]immediately after restoration and 1 year after restoration,and occurrence of adverse events.Results 1 month after restoration,there was no statistically significant difference in restoration effect scores between the two groups(P>0.05).At 1,3,6 months and 1 year after restoration,the restorative effect scores of the observation group were(12.54±0.80),(11.88±0.50)and(11.00±0.49)points,respectively,which were significantly higher than(11.70±0.76),(10.32±0.45)and(8.84±0.39)points of the control group,and the differences were statistically significant(P<0.05).Immediately after restoration,there was no statistically significant difference in BI,PD and AL between the two groups(P>0.05).At 1 year after restoration,BI,PD and AL in the observation group were significantly lower than those in the control group,and the difference was statistically significant(P<0.05).At 1 year follow-up,the incidence of adverse events was 4.55%in the observation group,which was significantly lower than 20.45%in the control group,and the difference was statistically significant(P<0.05).Conclusion Porcelain veneer restoration has better effect than full-porcelain crown restoration in oral cosmetic restoration,and it can effectively guarantee periodontal health,and the clinical application value is higher.
