目的:分析三种不同材料修复楔状缺损牙的临床效果。方法:101例患者360颗患牙随机分成三组,分别用玻璃离子、复合树脂和玻璃离子水门汀光固化夹层技术修复楔状缺损,修复1 a后复查,观察临床效果。结果:修复后1 a成功率分别是:玻璃离子组(A组)82.50%,复合树脂组(B组)89.17%,夹层技术(C组)97.50%。结论:夹层技术修复楔状缺损牙的临床效果优于玻璃离子、复合树脂,是一种较理想的修复技术。
Objective: To analyze the clinical effect of three kinds of different materials in repairing wedge-shaped defects. Methods: Three hundred and sixty teeth of 101 patients were randomly divided into three groups. The wedge-shaped defect was repaired by glass ionomer, composite resin and glass ionomer cements. The clinical effect was observed after 1-year recovery. Results: The successful rates of 1 year after repair were 82.50% in glass ionomer group (A group), 89.17% in composite resin group (B group) and 97.50% in sandwich group (C group). CONCLUSION: The clinical effect of sandwich technique in repairing wedge-shaped defect teeth is better than that of glass ions and composite resin, which is an ideal repair technique.
