The Influence of Different Resin Cements and Pretreatments on the Bond Strength between Zirconia and Cement

Abstract

The aim of this study was to analyze the in uence 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 signi cantly 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 signi cantly 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 signi cantly di erent (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 e ective 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. DOI: 10.12693/APhysPolA.125.313
