Purpose : The aim of this study was to evaluate the shear bond strength of four esthetic veneering materials on nickel‐chromium (Ni‐Cr) alloy.Materials and Methods : Forty square patterns (10 × 10 × 1.5 mm) were cast with Ni‐Cr, divided equally into four groups, and received four treatments for veneering: conventional porcelain‐fused‐to‐metal (PFM), Artglass, Targis/Vectris, and Biodent light‐cured prosthodontic composite resins. After sandblasting of the cast metal surfaces with 50 μm alumina, the composites were applied to the surfaces according to manufacturers' recommendations. Shear bond strength was determined at a crosshead speed of 0.5 mm/min. Results were analyzed statistically with Kruskal‐Wallis analysis of variance and multiple comparison tests.Results : Mean shear bond strength values were 34.96 MPa for PFM, 14.17 MPa for Targis/Vectris, 13.64 MPa for Artglass, and 10.56 MPa for Biodent. The PFM group exhibited significantly higher bond strength values compared with the other three groups ( p < 0.001).Conclusion : PFM showed considerably higher shear bond strength values than the three metal‐resin bonding techniques.
