Bond Strength of Self-adhesive Resin Cements to Ceramics

Abstract

Self-adhesive resin cement has been developed as a luting agent without pretreatment of the adherent surface. Though, these resin cements are used for indirect ceramics restoratives, the adhesive stability to the adherent surface is not clear. The purpose of this study was to examine the adhesive performance of self-adhesive cement to ceramics and dental casting alloy by determining the bond strength through SEM observation. The effects of ceramics primers on the adhesive properties were also examined. From the results of this study, bond strength of self-adhesive resin cements were higher than those of resin-modified glass-ionomer cements. No significant difference were found for shear bond strength. When a ceramics primer was not used for pretreatment, the predominant failure was adhesive failure. Though bond strength data were not influenced by the use of ceramics primers, the fracture mode after the bond strength test became more complex.
