目标
瓷贴面的整体临床表现在 5 年时进行评估。
方法和材料
一名操作者按照标准化临床程序，为 25 名患者（19 至 69 岁）的 87 颗上颌前牙安装了瓷贴面。 5 年回忆时，记录美观、边缘表现、活力、骨折率和患者满意度。
结果
回想起来，93% 的贴面在没有干预的情况下是令人满意的。其余7%出现临床上不可接受的问题，如复发性龋齿、烤瓷断裂、严重的临床微渗漏或牙髓反应。瓷贴面保留率100%，美观维护完美。只有 14% 的贴面在修复体的整个轮廓上表现出出色的边缘适应性；然而，轻微的边缘缺陷对临床表现的影响可以忽略不计。
结论
唇瓷贴面为前牙变色、畸形和排列不齐的保守治疗提供了可靠且有效的手术。
OBJECTIVE
The overall clinical performance of porcelain veneers was evaluated at 5 years.
METHOD AND MATERIALS
Porcelain veneers were placed on 87 maxillary anterior teeth in 25 patients (19 to 69 years) by a single operator following a standardized clinical procedure. At the 5-year recall, esthetics, marginal performance, vitality, fracture rate, and patient satisfaction were recorded.
RESULTS
At recall, 93% of the veneers were satisfactory without intervention. The remaining 7% presented clinically unacceptable problems such as recurrent caries, porcelain fracture, severe clinical microleakage, or pulpal reaction. The retention rate of the porcelain veneers was 100%, and the maintenance of esthetics was perfect. Only 14% of the veneers presented excellent marginal adaptation over the entire outline of the restoration; however, the impact of the slight marginal defects on the clinical performance was negligible.
CONCLUSION
Labial porcelain veneers offer a reliable and effective procedure for the conservative treatment of discolored, malformed, and malaligned anterior teeth.
