Abstract
An apparatus and method for electrolytic etching of cast dental alloys and pre-existing amalgam restorations provides a DC source for etching of the selected metalwork and an AC source for removal of the oxide coating produced by the etching process. Metal framework so etched and cleaned facilitate resin bonding as in resin-bonded retainers for fixed bridgework, resin-bonded crowns, resin-bonded orthodontic brackets, resin-coated amalgam and cast restorations, resin-coated partial denture clasps, and the like.
