【摘要】 选择３０个氢氟酸（ＨＦ酸）浓度－时间搭配点，测试瓷贴面复合体整体粘结抗剪强度。结果表明：ＨＦ酸蚀刻可增加陶瓷与牙釉质间粘结强度，ＨＦ酸浓度－时间的最佳搭配点为：２．５％－５．０ｍｉｎ；５．０％－５．０ｍｉｎ；７．５％－２．５ｍｉｎ；１０．０％－１．０ｍｉｎ；１５．０％－０．５ｍｉｎ。陶瓷－树脂－牙釉质的粘结破坏形式以混合破坏为主更多还原

【Abstract】 After HF acid etching under 5 different HF concentrations and 6 exposing times, shear bonding strength of porcelain to enamel were tested. The results showed that HF acid etching technique had a positive influence on the bonding strength of porcelain to enamel. The most favorable concertrationtime groups were 2.5%5.0 min, 5.0%5.0 min,7.5%2.5 min,10.0%1.0 min,15.0%0.5 min, and the debonding type of porcelainresinenamel composite body was mixed debonding.更多还原
