Abstract Purpose To determine the shear bond strength (SBS) between zirconium framework and resin cements after different surface conditioner methods and after application of 10‐methacryloyloxydecyl dihydrogen phosphate (MDP) based silane and a bonding agent mix. Materials and Methods 128 disc‐shaped zirconium‐oxide specimens were prepared. Specimens were placed in autopolymerizing acrylic resin. The bonding surface of specimens was smoothed consecutively with 600‐, 800‐, and 1200‐grit silicon carbide papers under water cooling. Eight groups were prepared: CJ, Co‐Jet; N, Nd‐YAG laser; E, Er‐YAG laser; NS, Nd‐YAG laser + silane; ES, Er‐YAG laser + silane; CJB, Co‐Jet + bonding agent; NSB, Nd‐YAG laser + silane + bonding agent; ESB, Er‐YAG laser + silane + bonding agent. SEM analysis was performed under 2000× magnification. Dual‐ and self‐cured resin cements were bonded to specimens, and shear force was applied. Data were analyzed with one‐way ANOVA and Tukey's multiple comparison test ( p < 0.05). Results The SBS values differed from each other among the groups. While the CJB group showed the highest values, the N group showed the lowest. The treatment with MDP‐based silane and bonding agent mix increased SBS values of each cement belonging to each group. SB values of dual‐cure resin cement were higher than those of self‐cure resin cements. Conclusion Different surface conditioner methods exhibit an important effect on the SBS of resin cements to zirconium. The application of MDP‐based silane and bonding agent mix enhanced SB values.
