Association of different primers and resin cements for adhesive bonding to zirconia ceramics.
PURPOSE To evaluate the shear bond strength ( SBS ) to zirconia ceramics using different associations of primers and resin cements . MATERIAL S AND METHODS Two blocks of LAVA zirconia ( 3Y-TZP ) were r and omly su bmi tted to an application of three different commercially available primers : Alloy Primer ( AP ) , Z-Prime Plus ( ZP ) , and Signum Zirconia Bond ( SZB ) . Nonprimed specimens were considered controls . After treatment , the 80 specimens ( 5 mm × 5 mm × 2 mm ) were r and omly cemented with one of the resin cements : Panavia F , Multilink , seT , and NX3 . For cementation , cylinders of resin cement were built on the ceramic surfaces using the SDI SBS apparatus . The specimens were su bmi tted to the SBS test . Fractured surfaces were observed under stereomicroscopy to determine the failure mode , and mean bond strength values were analyzed using the Kruskal-Wallis and Mann-Whitney tests ( α = 0.05 ) . RESULTS Signum Zirconia Bond had the highest SBS compared to all other primers and the control group , regardless of the resin cement used . The highest values were obtained when associating Panavia F with Signum Zirconia Bond . Alloy Primer increased bonding values when associated with seT cement only . When no primer was used , no statistical difference was observed among resin cements . All specimens fractured due to adhesive failure . CONCLUSION Signum Zirconia Bond is capable of increasing bonding values of resin cements to zirconia ceramics . Its association with Panavia F shows enhanced results when considering short-term adhesion to zirconia
