摘要
目的:探讨三种瓷贴面修复牙体预备方法的临床疗效。方法:采用唇面覆盖型贴面(I型)、唇切缘面覆盖型贴面(L型)、唇切邻面覆盖型贴面(U型)三种牙体预备方法瓷贴面方法,对36例患者共计108颗患牙行瓷贴面修复,于修复后1周、6个月、1年复诊,观察三种牙体预备方式的修复体保存完整度、颜色匹配、牙龈状况、边缘适合性的指标。结果:L型牙体预备瓷贴面修复后,在6个月随访时有1颗患牙修复体边缘有微小间隙,在1年随访时有2颗患牙修复体出现裂纹;U型牙体预备瓷贴面修复后l年,有1颗患牙修复体脱落。结论:选择适合的牙体预备方法进行全瓷贴面修复,均获得较理想的贴面修复效果。
Objective： The aim of this study was to evaluate the clinical effect of three kinds of porcelain laminate veneer preparation. Methods： 108 porcelain laminate veneers were fabricated for 36 patients using labial type（I-type）,labial-incisal type（L-type） and labial-incisal-lateral type（U-type）. Patients were revisited 1 week, 6 months and 1 year after the preparation to examine the integrity and color of the veneer, the gingival condition, and marginal sealability. Results： In the L-type group, 1 veneer was found micro-leakage in the labial shoulder in the 6 months follow-up. 2 veneers showed cracks in the 1 year follow-up. In the U-type group, 1 veneer was lost in the 1 year follow-up. Conclusion： The optimal selection of preparation is the key to achieve satisfactory effect.
