This study investigated the bonding performance of two different types of resin cements to computer-aided design/computer-aided manufacturing (CAD/CAM) composite blocks based on the shear bond strength (SBS) test. A silane-containing self-adhesive resin cement (Panavia SA Cement Universal) and resin luting cement (Block HC Cem) with a primer, were used. Specimens were fabricated from three different types of CAD/CAM composite blocks, and their surfaces were blasted with alumina. Resin cements were bonded to the specimens, and their SBSs were measured after 15 min, 24 h, and after being subjected to thermal cycling for 10,000 and 30,000 cycles. Three-way ANOVA for bond strength revealed that CAD/CAM composite block, resin cement and storage time significantly influenced the SBS values, and the three-way interactions between the evaluated factors, and all the interactions were significant. It was concluded that the bonding performance of resin cements to CAD/CAM composite blocks were material and storage period dependent.
本研究通过剪切粘接强度（SBS）试验，研究了两种不同类型的树脂水门汀与计算机辅助设计/计算机辅助制造（CAD/CAM）复合块的粘接性能。使用了一种含硅烷的自粘接树脂水门汀（Panavia SA Cement Universal）和一种带底漆的树脂水门汀（Block HC Cem）。从三种不同类型的 CAD/CAM 复合块中制备试件，并对其表面进行氧化铝喷砂处理。将树脂水门汀粘接在试件上，在 15 分钟、24 小时后以及经过 10,000 和 30,000 次热循环后，测量其 SBS 值。三因素方差分析表明，CAD/CAM 复合块、树脂水门汀和储存时间显著影响 SBS 值，评估因素之间的三因素相互作用以及所有相互作用均具有统计学意义。结论：树脂水门汀与 CAD/CAM 复合块的粘接性能取决于材料和储存时间。
