超薄瓷贴面前牙美学修复的临床效果评价

目的：评价超薄瓷贴面在前牙美学修复中的临床效果。方法对64例要求前牙美学修复患者的112颗前牙进行超薄瓷贴面修复，追踪24个月，采用改良加利福尼亚牙科协会-瑞格（Ryge）标准，对修复效果进行评价。结果在12个月复查时有2颗贴面发现切端折裂。在24个月复查时有1颗贴面发现远中切角部分折裂；另有1颗贴面边缘可探及间隙；5颗贴面边缘有较明显着色。所有复诊病例均未出现牙敏感及牙龈炎。结论超薄瓷贴面牙体预备量少，修复强度高，不易脱落折裂，具有良好的临床修复效果。

Clinical evaluation of anterior teeth aesthetic restoration with thin porcelain laminate veneer

Objective To evaluate the clinical restorative effect of anterior thin porcelain laminate veneers. Meth-ods Thin Porcelain laminate veneers were applied to 112 teeth of 64 patients for anterior aesthetic restoration. The fol-low-up time was 24 months. The veneers were examined with a modified Ryge criteria. Results The fracture of the in-cisal edge on 2 veneers was noticed after 12 months. After 24 months, the partial fracture of the distal incisal corner on 1 veneer was noticed; a gap was detected on the margin of another veneer and discoloration was observed on 5 ones. None of cases showed dentin hypersensitivity or gingivitis. Conclusion A satisfying effect could be gotten by using thin porcelain laminate veneer in the anterior teeth with the advantages of less tooth preparation, high repair strength, and not easy to fall off break.
