This in vitro study compared three methods of surface treating gold alloys to improve resin adhesion. The tensile bond strengths and modes of failure between specimen pairs cemented with a chemically adhesive resin were recorded. Heat-treated gold alloy specimens were significantly more resistant to bond failure under tensile loading than were either alumina-blasted or tin-plated gold specimens. There was no statistically significant difference in bond failure between aluminablasted and tin-plated gold specimens. The surface treatment altered the mode of failure from adhesive and/or for alumina-blasted and tin-plated gold specimens to cohesive (within the resin) for heat-treated gold specimens. Three case reports are presented to illustrate clinical applications of heat-treated gold alloys. e v i s e h o c - e v i s e h d a
