Title

Influence of Different Surface Treatments on the Shear Bond Strength of Resin Cement to Base Metal Alloys

Pages

  45-49

Abstract

 Introduction: This study aimed to investigate the effect of different surface treatments on the bond strength of resin cement to nickel-chrome (Ni-Cr) alloy. Methods: Forty disk-shaped specimens of Ni-Cr alloy were prepared and divided into 4 groups. In the first group, the specimens’ surface was sandblasted with 50 μ Al2O3 particles. In the second group, the specimens were prepared with the Er: YAG laser. In the third group, the specimens were prepared using the Er: YAG laser after sandblasting. In the fourth group, the specimens’ surface was covered with a thin layer of MKZ metal primer after sandblasting. Then the cylinders of composite resin were bonded to the treated metal surfaces using Panavia F2. 0 resin cement. All of the samples were subjected to 2000 thermal cycles. The Shear bond strength was tested using a universal testing machine at the crosshead speed of 0. 5 mm/min. The failure mode was also observed by a stereomicroscope. Data were analyzed using the one-way ANOVA and the Tukey HSD test at a significance level of 0. 05. Results: The Shear bond strength from the highest to the lowest were as follows: the Er: YAG laser group, the sandblast and MKZ primer combination group, the sandblast group, and the sandblast and Er: YAG laser combination group. The mean differences of Shear bond strength between the Er: YAG laser group and the sandblast group (P = 0. 047) and also between the Er: YAG laser group and the sandblast and Er: YAG laser combination group (P = 0. 015) were statistically significant. Conclusion: Among the different surface treatments employed in this study, Er: YAG laser treatment increased the Shear bond strength between the metal alloy and the resin cement (Pavnavia F2).
