title: In-office technique for selectively etching titanium abutments to improve bonding for interim implant prostheses.
abstract: A technique is described for increasing the surface area of a titanium abutment with hydrofluoric acid etching. This provides mechanical retention for acrylic resin and composite resins and can be easily and rapidly accomplished in both the laboratory and clinic.
