summary The purpose of this study was to evaluate the shear bond strengths of three dual‐cured resin luting cements (Linkmax HV, Panavia Fluoro Cement, and RelyX ARC) to glass‐infiltrated alumina‐reinforced ceramic material and the effect of four silane coupling agents (Clearfil Porcelain Bond, GC Ceramic Primer, Porcelain LinerM, and Tokuso Ceramic Primer) on the bond strength. The two type‐shaped of In‐Ceram alumina ceramic glass‐infiltrated specimens were untreated or treated with one of the four ceramic primers and then cemented together with one of the three dual‐cured resin luting cements. Half of the specimens were stored in water at 37°C for 24 h and the other half thermocycled 20 000 times before shear bond strength testing. Surface treatment by all silane coupling agents improved the shear bond strength compared with non‐treatment. The specimens treated with Clearfil Porcelain Bond showed significantly greater shear bond strength than any of the other three silane coupling agents regardless of resin luting cements and thermocycling except for the use of Panavia Fluoro Cement at 20 000 thermocycles. When the alumina‐reinforced ceramic material was treated with any silane coupling agent except GC Ceramic Primer and cemented with Linkmax HV, no significant differences in bond strength were noted between after water storage and after 20 000 thermocycles. After 20 000 thermocycles, all specimens except for the combined use of Clearfil Porcelain Bond or GC Ceramic Primer and Linkmax HV and GC Ceramic Primer and Panavia Fluoro Cement showed adhesive failures at the ceramic–resin luting cement interface.
