310个烤瓷贴面远期临床效果的回顾性分析

目的 评价完成修复1～8年的310个长石质烤瓷贴面的远期临床效果,以期为临床提供参考.方法 对完成修复1～8年的310个前牙或前磨牙长石质烤瓷贴而进行复查,参照改良美国公共健康协会(United States Public Health Service,USPHS)评价标准对烤瓷贴面的修复体完整度、修复体磨耗、颜色满意度、边缘染色、边缘适合性、继发龋、牙本质敏感症状及牙龈指数(gingival index,GI)8项指标进行评估,寿命表法统计烤瓷贴面1～8年存留率.结果 烤瓷贴面1～8年存留率分别为98.7%、98.0%、93.8%、93.2%、89.7%、81.8%、76.3%、76.3%.结论 烤瓷贴面修复技术的远期临床效果良好.

A retrospective study on the long-term clinical outcomes of 310 porcelain laminate veneers

Objective To investigate the long-term clinical outcomes of porcelain laminate veneers 1-8 years following delivery.Methods A total of 310 feldspathic porcelain laminate veneers on anterior teeth or premolars in 49 patients were included in the present study 1-8 years following delivery.All the subjects underwent a detailed clinical examination utilizing medified United States Public Health service(USPHS)criteria.Restoration integrity,abrasion,color satisfaction,marginal discoloration,marginal adaptation,secondary caries,postoperative sensitivity,and gingival index(GI)of the prostheses were evaluated according to modified USPHS criteria.The 1-8 year survival rates of the veneers were statistically analyzed using the life table method.Results The survival rates of porcelain laminate veneers were98.7%,98.0%,93.8%,93.2%,89.7%,81.8%,76.3%,and 76.3%in 1 to 8 years,respectively.Conclusions The long-term clinical outcomes of porcelain laminate veneers are satisfying.
