Abstract

The aim of this study was to determine the effect of laser surface treatment of Ni-Cr alloy on the tensile bond strength of a proprietary composite resin (Panavia 21) in comparison with a conventional sandblasting technique. Eighty cylinders of Ni-Cr were randomly allocated into the following groups: Group I - sandblasting only; Group II - low laser fluence (3.0 J/cm 2); Group III - medium laser fluence (4.0 J/cm2); Group IV - high laser fluence (4.9 J/cm2); Group V - sandblasting in combination with medium laser fluence (4.0 J/cm2). Specimens within groups were bonded into pairs with resin cement as per manufacturer's instructions. They were then de-bonded using a tensile test. The mean de-bond strengths (SD) were: Group I - 13.1 (4.2) MPa; Group II - 17.6 (5.8) MPa; Group III - 25.7 (11.8) MPa; Group IV - 22.6 (6.6) MPa; Group V - 41.8 (13.2) MPa. A statistically significant improvement (Bonferroni, p
