进行了一项实验室研究，以评估采用 All-Bond 2 粘合剂系统的各种处理方案粘合到瓷器表面的复合树脂的粘合强度。几种表面处理方法之间的24小时粘合强度存在显着差异。水储存 24 小时后的平均剪切粘合强度范围为 10.6 +/- 2.3 MPa 至 25.0 +/- 4.4 MPa。经过 3 个月的水储存和热循环后，九种表面处理方法的粘合强度显着下降 (p < 0.05)。 3 个月后，粘合强度范围为 0.1 +/- 0.1 MPa 至 17.4 +/- 2.0 MPa。采用氧化铝空气磨蚀，然后进行氢氟酸、硅烷偶联剂和未填充树脂的瓷器表面处理在 3 个月的水储存和热循环后产生的粘合强度明显高于其他九种瓷器表面处理技术（Cp < 0.05）。对脱粘样品的目视检查通常显示处理组的瓷器出现内聚破坏，平均粘合强度高于 13 MPa。
A laboratory study was conducted to evaluate the bond strength of composite resin bonded to porcelain surfaces by use of a variety of treatment regimens with the All-Bond 2 adhesive system. There were significant differences in the 24-hour bond strengths between several of the surface treatment methods. The mean shear bond strength after 24 hours of water storage ranged from 10.6 +/- 2.3 MPa to 25.0 +/- 4.4 MPa. Nine of the surface treatment methods showed a significant decrease (p < 0.05) in bond strengths after 3 months of water storage and thermocycling. After 3 months, the bond strengths ranged 0.1 +/- 0.1 MPa to 17.4 +/- 2.0 MPa. Porcelain surface treatment with aluminum oxide air abrasion followed by hydrofluoric acid, a silane coupling agent, and an unfilled resin produced a bond strength after 3 months' water storage and thermocycling that was significantly greater Cp < 0.05) than the other nine porcelain surface-treatment techniques. Visual examination of the debonded specimens generally showed cohesive failures in porcelain for the treatment groups with a mean bond strength above 13 MPa.
