This study evaluated porcelain repair by use of various surface treatments and hydrophilic bonding resins. The surface treatments were air abrasion (sandblasting), roughening with a diamond, etching with 9.6% hydrofluoric acid, and a combination of the latter two methods. A silane coupling agent was applied to all porcelain surfaces, and composite resin was bonded to porcelain with All-Bond 2, Amalgambond, or Clearfil Porcelain bonding agents. Shear bond strengths were determined on a universal testing machine. The most effective surface treatment was the combination of diamond roughening and hydrofluoric acid etching, but it was not significantly better than the other methods. The Clearfil Porcelain Bond system showed a greater repair strength than the other two materials but was statistically different only from Amalgambond resin.
本研究评估了使用各种表面处理方法和亲水性粘结树脂进行瓷修复的效果。表面处理方法包括空气喷砂（喷砂）、用金刚石打磨、用9.6%氢氟酸蚀刻以及后两种方法的组合。所有瓷表面均应用了硅烷偶联剂，并用全粘结2型、银汞粘结剂或Clearfil瓷粘结剂将复合树脂粘结到瓷上。在万能试验机上测定剪切粘结强度。最有效的表面处理方法是金刚石打磨和氢氟酸蚀刻的组合，但并不比其他方法显著更好。Clearfil瓷粘结系统显示出比其他两种材料更高的修复强度，但仅与银汞粘结树脂在统计学上有差异。
