This study evaluated the shear bond strength of a newly developed resin bonding system, including single-liquid ceramic primer and dual-cured resin luting agent, to 5 ceramic materials (feldspathic porcelain, machinable ceramic, In-Ceram Alumina, Procera AllCeram alumina, and Cercon). Ceramic specimens were cleaned with phosphoric acid, treated with primer, and bonded with a resin luting agent. Shear bond strength was determined after 24 hours of immersion in water and/or 10,000 thermocycles. There were no significant differences in bond strength before and after thermocycling for the 5 ceramic materials (P > .05). The findings indicate that the resin bonding system may offer an acceptable performance in terms of clinical success for the 5 ceramic restorations.
本研究评估了一种新开发的树脂粘结系统(包括单液陶瓷底漆和双固化树脂粘结剂)与5种陶瓷材料(长石质瓷、可加工陶瓷、In-Ceram氧化铝、Procera全瓷氧化铝和Cercon)之间的剪切粘结强度。陶瓷试件先用磷酸清洗,再用底漆处理,然后用树脂粘结剂粘结。在水中浸泡24小时和/或进行10000次热循环后测定剪切粘结强度。5种陶瓷材料在热循环前后的粘结强度无显著差异(P>.05)。研究结果表明,就这5种陶瓷修复体的临床成功率而言,该树脂粘结系统可能具有可接受的性能。
