目的
比较两种双固化复合树脂水门汀与多相复合树脂（实验）和玻璃陶瓷（对照）老化后的剪切粘结强度（SBS）。
方法
制备了70个计算机辅助设计/计算机辅助制造（CAD/CAM）块：24个多相复合树脂块（Lava Ultimate;实验）和12个对照块（第5组和第6组：6个IPS e.max CAD，6个IPS Empress CAD）。实验组的表面处理是：1）Al 2 O3气载颗粒磨损; 2）毛刺粗化; 3）二氧化硅包覆的氧化铝颗粒磨损;和4）氢氟酸（HF）酸蚀刻。每个研究组使用Variolink II（a）和RelyX Ultimate（B）作为骨水泥。每个治疗组，将4个骨水泥圆柱体粘附到经处理的骨块上（n = 12）。在热循环老化（10.000 X，5°C至55°C）之后，应用缺口边缘剪切测试。检查了故障模式。0.05的P值被认为是显著的。
结果
1a组（18.68 ± 3.81）和3a组（17.09 ± 3.40）与6a组（20.61 ± 4.10）相当。组5a（14.39 ± 2.80）与组1a、3a和4a（15.21 ± 4.29）无显著差异。2a组（11.61 ± 3.39）显示出最低的粘结强度。对于RelyX Ultimate样本，平均粘结强度为：1b（18.12 ± 2.84）> 4 b（15.57 ± 2.31）> 2b（12.34 ± 1.72）= 3b（11.54 ± 2.45）= 6 b（12.31 ± 1.87）> 5 b（0.78 ± 0.89）。失效模式分析表明，粘结强度值和失效模式（卡方）之间存在显著关联。
结论
SBS的复合水泥的多相复合树脂，是由氧化铝或二氧化硅包覆的氧化铝颗粒磨损处理是可比的对照组的债券。
AIM
To compare the shear bond strength (SBS) after aging of two dual-curing composite resin cements to multiphase composite resin (experiment) and glass-ceramics (control).
METHODS
Seventy computer-aided design/computer-aided manufacturing (CAD/CAM) blocks were prepared: 24 multiphase composite resin blocks (Lava Ultimate; experiment), and 12 control blocks (groups 5 and 6: 6 IPS e.max CAD, 6 IPS Empress CAD). Surface treatments of the experiment groups were: 1) Al2O3 airborne particle abrasion; 2) bur-roughening; 3) silica-coated aluminum oxide particle abrasion; and 4) hydrofluoric (HF) acid etching. Per study group, Variolink II (a) and RelyX Ultimate (b) were used as cements. Per treatment group, four cement cylinders were adhered to the conditioned blocks (n = 12). After thermocyclic aging (10.000x, 5°C to 55°C), notch-edge shear testing was applied. Modes of failure were examined. A P value of 0.05 was considered significant.
RESULTS
Groups 1a (18.68 ± 3.81) and 3a (17.09 ± 3.40) performed equally to 6a (20.61 ± 4.10). Group 5a (14.39 ± 2.80) did not significantly differ from groups 1a, 3a, and 4a (15.21 ± 4.29). Group 2a (11.61 ± 3.39) showed the lowest bond strength. For the RelyX Ultimate specimens, mean bond strengths were: 1b (18.12 ± 2.84) > 4b (15.57 ± 2.31) > 2b (12.34 ± 1.72) = 3b (11.54 ± 2.45) = 6b (12.31 ± 1.87) > 5b (0.78 ± 0.89). Failure mode analysis showed a significant association between bond strength values and modes of failure (chi-square).
CONCLUSION
The SBS of the composite cements to the multiphase composite resin that was treated by Al2O3 or silica-coated aluminum oxide particle abrasion is comparable to the bond of the control groups.
