摘　　要：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面进行复查，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（gingiva lindex，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。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 modified 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 were 98. 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.
