Abstract

Statement of Problem: Ceramics and resins belong to the earliest tooth restorative materials. Nowadays new generations of these materials have provided a revolution in cosmetic dentistry. Ceramic Optimized polymer (Ceromer) is a newly made product that the bond between this material and base metal alloys, which are used widely today, is paid too much attention.Purpose: The aim of this study was to evaluate the BOND STRENGTH of targis (Ceromer) to three types of base metal alloys through three different SURFACE TREATMENT METHODs.Materials and Methods: In this experimental study, ninety plates of Rexillium III, Silver cast and super cast alloys (30 5 0.4) were prepared and surface treated through three different methods (air oxidation, vaccum oxidation and sandblast). All samples were then veneered with 1.mm thickness of Targis. After thermocycling, three-point bending test was performed by universal testing machine (Instron) to evaluate the amount of forces at crack or fracture times in Targis. The type of failure (cohesive or adhesive) was also evaluated microscopically. Statistical analyses were made using 2-factor ANOVA and Duncan tests.Results: The type of SURFACE TREATMENT METHOD caused a statistically significant difference in force rate required for crack and fracture in Targis. Sandblasting was found as the best method. The type of alloys, in all three methods, had a significant effect just on crack creation attributing the largest amount of force to Rexillium III. Adhesive type of failure occurred mostly in super-cast alloys through air-oxidation method, and cohesive type was more among silver cast alloys and sandblast method.Conclusion: According to the results of this study, BOND STRENGTH between CEROMER MATERIALS and base metal alloys is significantly great and Rexillium III alloy associated with sandblast technique the best combination.
