title: One-bottle silane coupling agent containing 4-META.
abstract: The effectiveness of commercial and experimental silane coupling agents was evaluated by measuring their shear bond strengths to a ceramic disk. Experimental one-bottle silane coupling agents were prepared using 3-MPTS, 4-META, and resin monomers. The surfaces of two ceramic disks (IPS e-max, Ivoclar Vivadent AG, Schaan, Lichtenstein) were treated by a silane coupling agent to bond them to each other; this bonding was mediated by a commercial flowable resin composite (Clearfil Majesty LV, Kuraray, Tokyo, Japan). A commercial silane coupling agent (Clearfil Porcelain Bond Activator, Kuraray, Tokyo, Japan) modified by adding 4-META exhibited a significantly higher bond strength than the unmodified commercial one-bottle silane coupling agent. Among the tested materials, two experimental one-bottle silane coupling agents composed of 5% 4-META, 45% 3-MPTS, and 50% resin monomers exhibited statistically highest bond strengths.
