Bond strength of composite to metal mediated by metal adhesive promoters
Abstract:
The effectiveness of three metal primers in promoting the adhesive bond of composites to alloy systems commonly used in making ceramometal restorations was investigated. The results of this study indicated that the bond strengths attained with these tested metal primers are in general not high. Further research is needed for the development of a metal primer with an improved adhesive strength. Until then, dentists should continue to use the current methods of undercutting and roughening the metal surface in order to achieve additional retention.

Rivets are cylindrical steel fasteners with a specially designed head. During application, rivets are heated until white-hot and then inserted through pre-drilled holes in the steel sections. A pneumatic hammer is used to shape the exposed end into a second head, securing the sections together.
