Abstract

Abstract - The bond strengths of a silver-tin-zinc-indium alloy used with adhesive luting cements were investigated. The metal surfaces were primed with two metal conditioners designed for noble metal alloys or base metal alloys, or prepared using a Rocatec tribochemical coating unit. Two adhesive luting cements (Super-Bond C&B and Panavia F 2.0) were applied. It can be concluded that airborne-particle abrasion with alumina was effective, but the effects on the bond durability of both the metal conditioners and the tribochemical silica coating method were not clear. Such bonding behavior seems to be particular to this kind of silver-rich dental casting alloy.
