Chairside electrolytic etching of cast alloys for resin bonding.

A new technique and the instruments for using it for chairside electrolytically etching metal have been described. The technique simplifies the process and permits the dentist to etch castings for resin retention in the operatory. The method also applies to spot etching techniques for fixed restorations and removable partial dentures. Intraoral use of the technique was described.
