超薄瓷贴面修复前牙的临床效果评价

Clinical evaluation of anterior tooth restoration with minimal or non-prep all ceramic veneers

目的:评价超薄瓷贴面修复前牙的临床效果。方法:将30名要求前牙微创美学修复的患者按照牙色分为A组(四环素牙组)、B组(非四环素牙组),采用超薄瓷贴面进行修复。修复后1周,1年随访复查,根据改良Ryge标准评价临床疗效。结果:修复1周后A组患者对颜色满意的修复成功率76.39%,医师对颜色满意的修复成功率40.28%;B组医患对颜色满意度100%,两组医患对修复体满意度,患者高于医师,满意度差异具有统计学意义(P<0.05);1年后复查,四环素牙组颜色满意度上明显低于非四环素牙组,两组在修复体完整度、边缘合适性、牙龈健康状况上差异无统计学意义(P<0.05),两组均未出现术后敏感。结论:超薄瓷贴面对正常牙色的前牙具有良好的修复效果,修复特殊牙色时,能改善基牙颜色,但修复后颜色较难预期。

Objective： To evaluate color of esthetic rehabilitation of anterior teeth restored with minimal or non-prep all ceramic veneers. Methods： 30 patients were collected from Dalian stomatology hospital. All the patients selected were di-vided into two groups： 72 veneers of 9 patients with tetracycline teeth were restored in Group A; 66 veneers of 21 patients with non-tetracycline in Group B. All the selected teeth were restored with minimal or no-prep veneers. The veneers were examined at each appointment with an improved evaluation criterion of Ryge. Results： The ratio of patients＇ satisfaction index on all restorations in group A was higher than that of dentists after a week. The success rate of color in group B is 100%. During one year follow up, there were no statistical difference in the success rate of the integrity of restoration, marginal adaptation and gingival condition between the two groups. Conclusions： The appearance of non-tetracycline teeth restored with minimal or no-prep veneers was optimal. The color of tetracycline teeth restored with minimal or no-prep veneers improved significantly, but the color of teeth-veneer-complex did not completely match the expected color,
