Resin-metal bonding systems: a review of the Silicoating and Kevloc systems

The Silicoating and Kevloc systems are resin-metal attachment devices that are designed to improve bond strength and decrease microleakage at the resin-metal interface. Clinically, these systems can be used to place resin pontics and veneers, enhance cementation with resin cements, and bond the resin matrix to metal implant substructures. To provide practitioners contemplating the use of either modality with background information, a concise summary of the potential advantages of resin-metal bonding, the procedures required to establish the chemical bond, and the methods of evaluating laboratory studies are presented. Chemical bonding with these systems is technique sensitive. How the system is used may be as important to the final clinical results as is the choice of system.
