The tensile and shear bond strength of a conventional and a 4-meta self-cure acrylic resin to various surface finishes of CoCr alloy.
This study was designed to compare the tensile and shear bond strengths of two self-cure acrylic resins to cobalt-chromium alloy (CoCr) samples, prepared with six surface finishes. The strongest mean tensile bond strength was recorded between the 4-Meta acrylic resin and Silicoated cobalt-chromium alloy. The strongest mean shear bond strengths showed little variation between the 4-Meta acrylic resin and Silicoated, sandblasted and sandblasted/tinplated cobalt-chromium. This laboratory based study may have important implications for the future design of CoCr dentures.
