To investigate the long-term clinical outcomes of porcelain laminate veneers 1-8 years following delivery.
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.
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.
The long-term clinical outcomes of porcelain laminate veneers are satisfying.
研究瓷贴面修复完成后1至8年的长期临床效果。
本研究纳入了49例患者在前牙或前磨牙上制作的310颗长石质瓷贴面，观察时间为修复完成后1至8年。所有受试者均按照改良的美国公共卫生服务（USPHS）标准进行详细的临床检查。根据改良的USPHS标准，评估修复体的完整性、磨损情况、颜色满意度、边缘变色、边缘适合性、继发龋、术后敏感性以及牙龈指数（GI）。采用寿命表法对瓷贴面1至8年的生存率进行统计学分析。
瓷贴面在1至8年的生存率分别为98.7%、98.
