title: Comparison of bond strengths between adhesive and conventional acrylic resins to cobalt chromium denture base alloy.
abstract: In removable partial dentures there is normally no chemical bonding between the cast alloy and the poly(methylemethacrylate). Mechanical retention of the resin to the casting is required and presents a significant challenge during the design of partial dentures. Recently developed adhesive denture base resins which contain the monomer 4-methacryloxyethyl trimellitate anhydride can create a chemical bond to partial denture alloys. This study investigated the bond strength of adhesive denture base resin (Metafast) and conventional acrylic resin (Croform x 10) to partial denture alloy (CoCr) under three different storage conditions (dry, water, water with thermocycling). The results showed that the bond strength of the conventional acrylic resin (Croform x 10) was less than the bond strength of the adhesive denture base resin (Metafast) and the storage environment had a significant effect upon the bond strength of both resins.
