This cross-sectional study compared the periodontal health and clinical acceptability of maxillary incisors restored with porcelain veneers vs. porcelain-fused-to-metal crowns. The authors evaluated 60 patients, a total of 120 restorations, in groups according to the age of the restorations (zero to 60 months). Margins of veneers were generally more supragingival with less gingival inflammation. All veneers were clinically acceptable, while 5 percent of PFMs failed because of secondary caries.
这项横断面研究比较了用瓷贴面修复与烤瓷熔附金属冠修复的上颌切牙的牙周健康状况和临床可接受性。作者根据修复体的使用年限（0至60个月）将60名患者（共120个修复体）分组进行评估。瓷贴面的边缘通常更位于龈上，牙龈炎症较少。所有瓷贴面在临床上均可接受，而5%的烤瓷熔附金属冠因继发龋而失败。
