Comparative Evaluation of the Bond Strength of Different Base Metal Alloys With Porcelain-An Invitro Study

Abstract

Results: Student't' test revealed no significant difference in the porcelain bond strength between nickelchromium and cobalt-chromium alloys-Commend and Lithecast respectively. Conclusion: Within the limitations of the study, no significant difference was noted between nickel-chromiumand cobalt-chromium alloy with respect to the bond strength with porcelain. Hence taking into consideration the economic effectiveness of nickel-chromium alloys, they can be used as the core material for metal-ceramic restorations in place of cobalt-chromium alloys except in nickel-allergic patients.
