The aim of this study was to analyze the inuence of various luting materials and surface treatments on adhesive strength for zirconia ceramics and luting cements. The zirconia framework specimens were made into cylinders. Prior to cement, zirconia framework specimens underwent various surface treatments (sandblasting with 110 µm Al2O3 particles, milling with 240-grift silicon sand paper and silanization). Resin luting cement and glass ionomer luting cement were then applied on the surface of zirconia specimens. The specimens were then subjected to a shear force. The fractured surfaces were visually analyzed by scanning electron microscopy. The shear bond strength values of resin luting cement bonded to zirconia specimens were signicantly higher than glass ionomer luting cement bonded to zirconia specimens (P < 0.05). The shear bond strength values of zirconia specimens sandblasted with 110 µm Al2O3 particles were signicantly higher than those milled with silicon carbide papers and underwent silanization (P < 0.05). The shear bond strength values of zirconia specimens milled with silicon carbide papers and underwent silanization were not signicantly dierent (P < 0.05). The highest shear bond strength values were achieved when the zirconia specimens were sandblasted and bonded to resin luting cement. Airborne-particle abrasion was an eective method which could enhance the bond strength of zirconia ceramics and cements. The resin luting cement exhibited a higher bond to zirconia than glass ionomer luting cement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
