目的：本研究以两种空气粒子磨耗法，评估两种树脂复合黏接剂与氧化锆陶瓷基材间的剪切黏结强度。研究方法：两种树脂复合粘固剂，RelyX Unicem（3 M ESPE）和Panavia F（Kuraray），各自具有酸性组合物，与含有Al 2 O3和SiO2（Rocatec系统，3 M ESPE）的氧化锆（DCS Dental AG）基底和两种空气颗粒磨损方法组合使用。在将样品水储存一周或水储存24小时后热循环后，测试树脂复合物水泥与基材的剪切粘结强度。结果如下：Rocatec处理的RelyX Unicem树脂复合骨水泥样本（分别为20.9 +/- 4.6 MPa和20.1 +/- 4.2 MPa，n=12）显示出最高的剪切粘结强度。或者，Panavia F树脂水泥样品在两种储存条件下均获得最低值，即水储存一周（17.7 +/-8.9 MPa）或水储存24小时后热循环（16.3 +/- 4.9 MPa）。储存条件或颗粒磨损系统均不显著影响剪切粘结强度（ANOVA，p > 0.05）。结论：得出的结论是，两种不同的表面处理方法和储存条件不会显著影响Panavia F和RelyX Unicem树脂复合胶合剂与氧化锆的粘结性能。
Objective: This study evaluated the shear bond strength of two resin composite luting cements to zirconium oxide ceramic substrate using two air-particle abrasion methods. Methods: Two resin composite cements, RelyX Unicem (3M ESPE) and Panavia F (Kuraray), each with an acidic composition, were used in combination with a zirconium oxide (DCS Dental AG) substrate containing Al2O3 and SiO2 (Rocatec system, 3M ESPE) and two air-particle abrasion methods. The shear bond strength of the resin composite cement to the substrate was tested after the samples were either water-stored for one week or thermocycled following 24 hours of water storage. Results: The RelyX Unicem resin composite cement specimens with the Rocatec treatment (20.9 +/- 4.6 Mpa and 20.1 +/- 4.2 MPa, respectively, n=12) demonstrated the highest shear bond strength. Alternatively, the lowest values were obtained for the Panavia F resin cement samples, with Al2O3 air-particle abrasion in both storage conditions, water storage for one week (17.7 +/- 8.9MPa) or thermocycling after 24 hours of water storage (16.3 +/- 4.9 MPa). Neither storage condition or particle abrasion system significantly affected shear bond strengths (ANOVA, p > 0.05). Conclusion: It was concluded that two different surface conditioning methods and storage conditions did not significantly affect the bonding properties of Panavia F and RelyX Unicem resin composite luting cements to Zirconia.
