摘要
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。

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 on1 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.
