The present study investigated the bond strength and aging resistance performance of five resin-based luting agents to zirconia. A total of 100 large blocks (10.0 mm × 10.0 mm × 2.5 mm) and 100 small blocks (4.0 mm × 4.0 mm × 2.5 mm) of zirconia were airborne-particle abraded and randomly divided into five groups: (RelyX Ultimate [RUl]; Panavia F [PF]; Clearfil SA Luting [SAC]; Multilink Speed [MS]; and RelyX Unicem [RUn]). The small blocks were bonded to the large blocks using the resin-based luting agents. Shear bond strengths (SBS) and failure mode were determined before and after 5,000 thermocycles. After being stored in water for 24 h, the SBS were MS > PF > RUl > SAC > RUn (P < 0.05). After 5,000 thermocycles, the SBS were MS > SAC ≈ RUl > PF ≈ RUn (P < 0.05); the SBS of the PF, MS, and RUn groups were lower than that before 5,000 thermocycles (P < 0.01). Adhesive failure, cohesive failure, or mixed failure occurred in the specimens. In general, Clearfil SA Luting, a self-adhesive resin-based luting agent containing 10-methacryloxy decyl diphosphate, had good initial and durable SBS to zirconia and was a better adhesive.
本研究调查了五种树脂类粘接剂与氧化锆的粘接强度和耐老化性能。总共100个大的氧化锆块（10.0毫米×10.0毫米×2.5毫米）和100个小的氧化锆块（4.0毫米×4.0毫米×2.5毫米）进行空气颗粒喷砂处理，并随机分为五组：（RelyX Ultimate [RUl]；Panavia F [PF]；Clearfil SA Luting [SAC]；Multilink Speed [MS]；和RelyX Unicem [RUn]）。使用树脂类粘接剂将小块与大块粘接在一起。在5000次热循环前后测定剪切粘接强度（SBS）和失效模式。在水中储存24小时后，SBS为MS > PF > RUl > SAC > RUn（P < 0.05）。5000次热循环后，SBS为MS > SAC ≈ RUl > PF ≈ RUn（P < 0.05）；PF、MS和RUn组的SBS低于5000次热循环前（P < 0.01）。标本中出现了粘接失败、内聚破坏或混合破坏。总体而言，Clearfil SA Luting是一种含有10 - 甲基丙烯酰氧基癸基二磷酸的自粘接树脂类粘接剂，对氧化锆具有良好的初始和持久SBS，是一种较好的粘接剂。
