    Abstract:
    Polymer substitution into proprietary 4-methacryloxyethyltrimellitate anhydride (4META) resins creates tooth coloured veneers for cobalt-chromium overlay dentures. The elastic moduli and shear-bond strengths of proprietary resins (matched) and resins polymerised from 4META monomers and substituted polymers (unmatched) were determined. Bond strengths were similar for matched and unmatched heat curing resins (mean 14.1 (SD 1.6 MPa)) but differed for matched (6.9 (SD 1.3) MPa) and unmatched self-curing resins (5.7 (SD 0.9) MPa). Preparation of the alloy surface immediately before packing with resin dough provided significantly higher bond strengths. Structural examination in a scanning electron microscope suggested that bonds developed by unmatched resins may provide less satisfactory clinical performance.
