Abstract

Introduction: In modern dentistry, as the patientís demand for aesthetic dentistry increases, the use of tooth-coloured restorative material increase correspondingly. One among them is the use of Porcelain Fused to Metal (PFM) restorations. However, fracture of PFM crown is a common problem in restorative dentistry. Various methods have been advocated to repair fractured porcelain.

Aim: The aim of present study was to evaluate the efficiency of the two different bonding systems in reference to three different surface treatments on Nickel Chromium (Ni-Cr) alloys by evaluating the shear bond strength at metal and resin interface.

Materials and Methods: A total of 80 Ni-Cr alloys measuring 1x1 cm square blocks were cast using lost wax technique. After casting, the specimens were grouped into four groups based on the surface treatments planned. The four groups were further subdivided into two subgroups based on the bonding technique. The subgroup A samples was treated with Single Bond Universal (SBU) and subgroup B samples was treated with Alloy Primer (AP) and SBU. After surface treatment of the sample, a clear plastic tube measuring 4 mm diameter and 4 mm length was placed and composite resin was packed and cured. Shear bond testing of all the groups was performed on Universal testing machine.

Results: The means and standard deviations of SBS values in MPa were calculated for each group, and the results were statistically analysed with one-way ANOVA and Tukey HSD tests. All statistical analyses were performed using the SPSS software version 10.0.

Conclusion: Within the limitations of this in vitro study, Erbium-doped Yttrium Aluminium Garnet (Er-YAG) Laser treated alloy surfaces bonded along with AP displayed highest shear bond strength and subgroup B samples bond strength was significantly higher.
