超薄贴面与传统贴面修复的效果比较

Comparisonof clinical effect of ultra-thinceramic veneers and porcelain laminate veneers

目的比较超薄贴面与传统贴面修复的短期临床效果。方法选择2014年7月至2015年7月在安徽医科大学口腔医学院进行贴面修复的34例患者,共111个修复贴面,将采用超薄贴面的54例修复体作为试验组,传统贴面的57例修复体作为对照组。贴面修复1年后复查,由贴面修复医师对基牙敏感性、继发龋、牙龈情况及贴面颜色、边缘密合性、边际着色情况进行检查,对两组复查结果进行比较分析。结果试验组和对照组继发龋、术后敏感、边缘着色均为A级,颜色满意度、边缘密合性和牙龈反应为A级或B级,两组差异无统计学意义(P>0.05)。结论超薄贴面修复的短期临床效果不亚于传统贴面修复。

Objective To compare the clinical results of ultra - thin ceramic veneers and porcelain laminate veneers. Methods Af-ter one year of the operation,we reviewed 34 patients with 111 restorations in the region of anterior tooth,who were treated in the stomatologi-cal Hospital of Anhui Medical University from July 2014 to July 2015 including 54 ultra - thin veneers and 57 porcelain laminate veneers. We recorded the postoperative sensitivity, caries and gingival reaction of the teeth, the color match, marginal discoloration and marginal adaptation of the veneers,and analysed the results between the two groups. All the examinationwas performed by only one doctor. Results The caries, postoperative sensitivity and marginal discoloration were in grade A, the color match, marginal adaptation and gingival reaction of the two groups were in grade A or B, and there was no significant difference between the two groups （P 〉0. 05）. Conclusion The ultra - thin ce-ramic veneers have no worse clinical effect than porcelain laminate veneersin a short - term period of time.
