Comparison of bond strengths between adhesive and conventional acrylic resins to cobalt chromium denture base alloy.
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.
