摘要/Abstract

摘要： 摘要目的：探讨不同牙体预备方法对瓷贴面成功率的影响。方法：采用唇面覆盖型（I型）、唇切缘覆盖型（L型）、唇切邻面覆盖型（U型）三种牙体预备方法，对29 例患者共计97颗患牙行瓷贴面修复，于修复后 1 周、6个月、12个月、18个月复诊，观察不同牙体预备方式的修复体保存完整度、颜色匹配、边缘适合性、术后过敏等指标。结果：I型在第12月随访时有1例修复体出现裂纹，L型在第12月和18月随访时各有1例修复体出现裂纹和边缘有微小间隙，U型在第6月有1例修复体在颜色和半透明度上与邻牙不一致，第18月随访时有1例修复体出现裂纹，3种牙体预备方式瓷贴面成功率没有明显差异。结论：选择合理的牙体预备方式进行瓷贴面修复，能够获得较佳的修复效果。

Abstract: Abstract Objective：To explore the achievement rates of porcelain laminate restoration based on different preparation designs. Methods：29 patients and 97 porcelain laminate veneers were prepared by facies labialis overlap (typeI), incisive edge overlap (type L) and finishing lines extended proximally (type U). And veneers' integrity, fracture, the marginal situation and color match were evaluated at 1week, 6months, 12 months and 18months.Results: There was 1 failure at 12 months preparaded by typeI, and 1failure at 12months and 1 failure at 18 months prepared by typeL, and 1failure at 6months and 1 failure at 18 months prepared by typeU. There ware no significent difference about achievement rates between 3 type preparations. Conclusion: Excellent effects porcelain laminate restorations were obtained by choiced reasoned tooth preparation.
