Enhance the bonding of cement to ceramic surface with a variety of ceramic surface modifications have been established. Air-abrasion using alumina particles, hydrofluoric acid has been shown to provide micromechanical interlocking at the ceramic-resin interface. The aim of the present study was to evaluate the effect of two surface treatments; acid etching and sandblasting; on the shear bond strength of cemented newly introduced zirconia-reinforced lithium silicate ceramics following thermocycling. Methods: 24 discs of Zirconia- reinforced glass ceramics (Celtra Duo) were tested using 10% hydrofluoric acid for 20 s (control group) and 50 µm aluminum oxide for 60 s at 10 mm distance from the nozzle tip of sandblasting machine. Subsequent to the surface treatments, both groups were salinized and cemented to composites background discs using self-adhesive dual cure resin cement (BisCem). All sample were subjected to 2500 thermal cycle shear bond strength and failure mode was evaluated. The results of the t-test indicated that the bond strength value is significantly influenced by the surface treatment method. It was found that hydrofluoric acid group recorded statistically significantly higher shear bond strength mean value (10.81 MPa) than aluminum oxide sandblasting group (7.76 MPa) as indicated by t-test (t = 2.9, p = 0.0109 < 0.05). Conclusion: failure mode showed a relation between the bond strength and the failure type mixed failure showed with higher bond valves and cohesive failure accompanied with lowest bond strengthen values. The shear bond strength of zirconia reinforced lithium silicate (Celtra Duo) ceramic cemented to resin cement was affected by the type of surface treatment.

已经建立了通过各种陶瓷表面改性来增强水泥与陶瓷表面的粘结的方法。已证明使用氧化铝颗粒和氢氟酸进行空气磨蚀可在陶瓷-树脂界面提供微机械互锁。本研究的目的是评估两种表面处理的效果。酸蚀和喷砂；热循环后胶结的新型引入的氧化锆增强硅酸锂陶瓷的剪切粘结强度 方法：在距喷砂机喷嘴尖端10 mm处，使用10％氢氟酸20秒钟（对照组）和50 µm氧化铝60秒钟，测试24片氧化锆增强玻璃陶瓷（Celtra Duo）。在表面处理之后，两组均进行了盐化，并使用自粘双固化树脂胶粘剂（BisCem）固结在复合材料背景盘上。使所有样品经受2500次热循环剪切粘合强度并评估破坏模式。结果t检验表明，结合强度值受表面处理方法的影响很大。通过t-检验表明，氢氟酸组记录的剪切键强度平均值（10.81 MPa）明显高于氧化铝喷砂组（7.76 MPa），如t检验所示（t  = 2.9，p  = 0.0109 <0.05）。结论：破坏模式表明了粘结强度与破坏类型之间的关系，混合破坏表现为较高的粘结阀和内聚破坏，而粘结强度最低。氧化锆增强硅酸锂（Celtra Duo）陶瓷与树脂水泥的剪切粘结强度受表面处理类型的影响。
