Purpose: This laboratory study compared the shear bond strength between three indirect resin composites and a noble alloy using their respective bonding systems. Materials and Methods: One hundred twenty disks cast in a medium-gold, high-noble metal-ceramic alloy (V-Deltaloy) were divided equally into four groups and received different treatments for veneering: Conventional feldspathic porcelain (Omega) was applied on one set of specimens to be used as a control, and three indirect resin composites (Artglass, Sculpture, Targis) with their respective bonding systems were used for the other groups. The specimens were tested in a parallel shear test, half of them after 24-hour dry storage at room temperature and the rest after 10-day storage in normal saline solution at 37°C and thermocycling. The fractured specimens were evaluated to determine the nature of the failure. Results: The mean shear bond strength values (in MPa), before and after wet storage and thermocycling, were 30 and 23 for the metal-ceramic group, 29 and 23 for the Artglass group, 20 and 19 for the Sculpture group, and 17 and 14 for the Targis group, respectively. The metal-ceramic and Artglass groups exhibited significantly higher bond strengths than the other two groups. All specimens, with the exception of the Sculpture group, showed a significant decrease in bond strength after wet storage and thermocycling. Conclusion: No group exceeded the shear bond strength of the metal-ceramic group, but the Artglass group with its respective metalresin bonding system exhibited similar bond strengths. The Sculpture group showed a stable bond after water storage and thermocycling. Int J Prosthodont 2003;16:635–639.
