氟斑牙烤瓷贴面美学修复临床效果观察

目的 观察氟斑牙应用烤瓷贴面进行美学修复的中长期效果.方法 按照对接式烤瓷贴面牙体制备标准,对11名患者的132颗氟斑牙进行牙体制备,用Dsign烤瓷贴面进行美学修复.采用改良Ryge标准进行临床效果评价,分别在修复后1.0周,0.5、1.0、1.5、2.0年复诊时检查边缘适合性、贴面边缘变色、继发龋、术后敏感、颜色匹配5项指标,并计算各指标A级率.结果 对132颗氟斑牙应用烤瓷贴面进行美学修复,5次复诊检查,边缘适合性A级率均为85%以上;贴面边缘变色A级率均为90%以上;继发龋A级率均为99%以上;术后敏感A级率均为75%以上;颜色匹配A级率均为70%以上、B级以上率为100%.结论 氟斑牙可以通过烤瓷贴面进行美学修复,中长期效果良好且稳定.

Abstract：

Objective To evaluate the long term clinical effect of porcelain laminate veneer esthetic restoration for fluorosis teeth. Methods One hundred and thirty-two fluorosis teeth of 11 patients were restored with porcelain laminate veneer for esthetic purpose and the clinical effects were evaluated with modified Rygescriteria at 1.0 week, 0.5-year, 1.0-year, 1.5-year, and 2.0-year recalled time. Results After 2.0 years application, none of the veneers debonded, "A" degree rate of marginal adaptation was more than 85%, "A" degree rate of cavosurface marginal discoloration was more than 90%, "A" degree rate of secondary caries was more than 99%, "A" degree rate of post-operative sensitivity was more than 75%, and "A" degree rate of color match was more than 70%, "B" degree rate of color match was 100%. Conclusions The research indicates that the porcelain laminate veneer is a good esthetic restoration method for fluorosis teeth and the long term clinical effect is stable.
