Abstract:

An alternative to the metal ceramic restoration has been the resin veneer crown. The resin veneer offers the advantages of low cost, ability to make clinical repairs, lack of wear to opposing teeth, and ease of fabrication. Clinical use of the resin veneer has been limited die to problems associated with the resin including low resistance to abrasion, high water sorption, a high coefficient of thermal expansion, low proportional limit, and a low modulus of elasticity. Improvements realized in composite resin technology have prompted the introduction of a number of composite resin veneering materials for prosthodontic applications. An electrochemical tin plating technique has been suggested for bonding composite veneering resins in lieu of conventional mechanical retention. The adhesive bonding of veneering resins to castings would prove beneficial by improving esthetics and eliminating the percolation of fluids at the resin-metal interface. The purpose of this investigation was to examine the shear bond strength of a composite resin processed to gold and base metal specimens that were treated with an electro-chemical tin plating technique. uniform specimens were cast in a gold alloy and a base metal. Conventional retentive beads on the gold alloy and electroetching of the base metal served as controls in this investigation.
