This study evaluated the effect of different ceramic primers and heat treatment of silane coupling agents on bond strength of resin cement to glass ceramic. Five ceramic primers (Clearfil Ceramic Primer/CCP, MonoBond-S, ProSil, RelyX Ceramic Primer and Silano) and one conventional resin cement (RelyX ARC) were tested. Lithium disilicate-based ceramic plates were previously etched with hydrofluoric acid, except for CCP (n = 10). All silane agents were applied to ceramics according to the manufacturer’s instructions and primed ceramics plates were heated (in oven at 100 °C for 1 min) or not before resin cement placement. Dual-cure resin cement was mixed and inserted in tubes (0.75 mm diameter × 1 mm height) that were positioned over primed ceramic surfaces. Micro-shear testing was performed using a universal testing machine. Bond strength data were analyzed using two-way ANOVA and Tukey’s test (5%). Ceramic primer heating did not improve the bond strength of the resin cement to lithium disilicate. Most of ceramic primers did not indicate significant difference in bond strength among them; however, CCP yielded the lowest bond strength among the ceramic primers. In conclusion, when the silane was applied on etched surface the bond strength was higher and heat treatment of silane coupling agents did not affect the bond strength.

陶瓷底漆和硅烷化后热处理对树脂水泥与二硅酸锂基陶瓷结合强度的影响

这项研究评估了不同陶瓷底漆和硅烷偶联剂的热处理对树脂水泥与玻璃陶瓷结合强度的影响。测试了五种陶瓷底漆（Clearfil陶瓷底漆/ CCP，MonoBond-S，ProSil，RelyX陶瓷底漆和Silano）和一种常规的树脂胶粘剂（RelyX ARC）。除CCP（n = 10）外，预先用氢氟酸蚀刻了基于二硅酸锂的陶瓷板。根据制造商的说明，将所有硅烷试剂均施用于陶瓷，然后在放置树脂胶结剂之前，先加热底漆陶瓷板（在100°C的烤箱中加热1分钟）。混合双固化树脂胶粘剂，并将其插入置于底漆陶瓷表面上方的管子（直径0.75 mm×高度1 mm）中。使用通用测试机进行微剪切测试。使用双向方差分析和Tukey检验（5％）分析粘结强度数据。陶瓷底漆的加热并没有提高树脂胶泥与二硅酸锂的粘合强度。大多数陶瓷底漆在它们之间的粘结强度上没有显着差异。然而，在陶瓷底漆中，CCP的结合强度最低。总之，当将硅烷施加到蚀刻的表面上时，结合强度较高，并且硅烷偶联剂的热处理不影响结合强度。
