title: Bond strength of cements to nickel-chromium and silver-palladium alloys.
abstract: The bonding of zinc phosphate, polycarboxylate, and reinforced ZOE cements to nickel-chromium and silver-palladium alloys was measured by cementing flat surfaces of the metals together. Polycarboxylate cement produced higher bond strengths than the other two cements to both metals. Polycarboxylate cement bonded better to nickel-chromium alloys than to a silver-palladium alloy. Zinc phosphate and reinforced ZOE cements had similar bond strengths except for Biobond, to which zinc phosphate cement provided higher bond strength. Polycarboxylate cement failed cohesively to both types of metals, and zinc phosphate and reinforced ZOE cements failed adhesively.
