Shear bond strength evaluation of different veneering systems on Ni-Cr alloys.
J Prosthodont. 2007 Jan-Feb; 16(1):31-6.JP

Abstract

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 x 10 x 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 micro m 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.
