Effect of Tin-Plating Upon Adhesive Bonding of Polycarboxylate Cements.

摘要

It has been suggested that tin-plated gold surfaces would more easily be adhered to by polycarboxylate cement. Controlled tin plating studies were carried out to test this hypothesis. It was found that scrupulous cleaning of the gold surface produced adhesive bonding that equalled bond strength to tin plated surface. Cement failures were cohesive rather than adhesive suggesting that bond strengths approach cohesive strength of cement. (Author)
