Silane-Containing Universal Adhesives Influence Resin-Ceramic Microtensile Bond Strength

Background: Silane-containing universal adhesives (UAs) are marketed as adhesion promotors for glass-ceramics. Objectives: This study aimed to evaluate the priming capacity of γ-methacryloxypropyltrimethoxysilane (γMPTS)-containing and γ-methacryloxypropyltriethoxysilane (γMPTES)/3-(aminopropyl)triethoxysilane (APTES)-containing lithium disilicate ceramic (LDC). Materials Methods: Etched LDC discs were distributed into four groups according material used: (control), no priming; (MBN), was primed with a primer (Monobond N); (SBU), γMPTS-containing UA (Single Bond Universal Adhesive) used primer; (SBP), γMPTES/APTES-containing (Scotchbond Plus primer. cemented using dual-cure resin cement, then sectioned microbeams microtensile bond strength (μTBS) evaluation. Failure modes assessed. Results: MBN application showed highest μTBS among all groups. (SBP) resulted in considerably higher compared (SBU) or control group. The mixed failures most predominant Conclusions: effect silane-containing UAs on resin-ceramic is dependent. Although improved bonding LDC, either tested cannot be considered an alternative separate silanization (priming) step
