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
Select 30 hydrofluoric acid (HF acid) concentration - time with points to test the overall bonded veneer composite shear strength. The results show that HF acid etching can increase the bonding strength between ceramic and enamel. The best matching point of HF acid concentration - time is 2.5% -5.0min, 5.0% -5.0min, 7.5 % -2.5 min; 10.0% -1.0 min; 15.0% -0.5 min. Ceramics - Resin - Enamel bond damage to the main form of mixed destruction
