本研究的目的是评价树脂基胶粘剂与摩擦化学(TBC)处理和两种不同的磷酸酯类单体联合处理所获得的部分稳定的四方氧化锆(Y-TZP)的粘结耐久性。分别用两种磷酸酯单体(EP：Epricord不透明底漆，AZ：AZ底漆)进行表面改性，然后使用树脂基胶粘结剂(RELY-X ARC)。粘接试件放在37摄氏度的去离子水中储存24小时。其他组接受30,000次热应力循环以进行耐久性测试。剪切粘结试验用万能试验机以1 mm/min的速度进行。EP和AZ联合处理的TBC在热应力后的剪切粘结强度与贮藏24 h后的剪切粘结强度无显著差异(p>；0.05)，使用磷酸酯单体联合处理可以获得持久的粘结。
The aim of the present study was to evaluate the bonding durability of resin-based luting cement to partially stabilized tetragonal zirconia (Y-TZP) achieved by combination treatment of tribochemical (TBC) treatment and two different phosphate acid ester monomers. Two phosphate acid ester monomers (EP: Epricord opaque primer, AZ: AZ primer) were applied to each surface modification followed by application of resin-based luting cement (Rely-X ARC). Bonding specimens were placed in deionized water at 37 degrees C and stored for 24 h. The other groups were subjected to 30,000 cycles of a thermal stress for the durability test. Shear bond tests were done using a universal testing machine at 1 mm/min. Shear bond strengths of combination treatments using EP and AZ on TBC treatment after thermal stress showed no significant difference (p>0.05) compared with those of storage after 24 h. Combination treatment using phosphoric acid ester monomer could achieve a durable bond.
