This study evaluated the effects of ceramic surface treatment agents on shear bond strengths to ceramic materials with and without thermocycling. Ceramic plates were prepared from feldspathic ceramic; AAA, lithium disilicate ceramic material; IPS e.max Press, zirconia ceramic; Lava. Ceramic surfaces were pretreated with one of five surface treatment agents (Clearfil PhotoBond mixed with Porcelainbond activator (PB), Clearfil SE One mixed with Porcelainbond activator (SO), Ceramic Primer (CP), Universal Primer (UP), Scotchbond Universal (SU)), and then a resin cement (Clapearl DC) was filled. After 0, 5,000, and 10,000 thermocycles, micro-shear bond strengths between ceramic-cement interfaces were determined. SU exhibited significantly lower initial bond strength to AAA and e.max than PB, SO, CP, and UP. For Lava, PB, SO, CP and SU exhibited higher initial bond strengths than UP. Thermocycles reduced bond strengths to all the ceramic materials with any surface treatment.
本研究评估了陶瓷表面处理剂对经过和未经过热循环的陶瓷材料的剪切粘结强度的影响。陶瓷板由长石质陶瓷（AAA）、二硅酸锂陶瓷材料（IPS e.max Press）、氧化锆陶瓷（Lava）制备而成。陶瓷表面用五种表面处理剂之一进行预处理（Clearfil PhotoBond与瓷粘结活化剂（PB）混合、Clearfil SE One与瓷粘结活化剂（SO）混合、陶瓷底漆（CP）、通用底漆（UP）、Scotchbond通用型（SU）），然后填充树脂粘结剂（Clapearl DC）。在0、5000和10000次热循环后，测定陶瓷 - 粘结剂界面之间的微剪切粘结强度。SU对AAA和e.max的初始粘结强度明显低于PB、SO、CP和UP。对于Lava，PB、SO、CP和SU的初始粘结强度高于UP。热循环降低了所有经过任何表面处理的陶瓷材料的粘结强度。
