A three-appointment alternative treatment protocol for fabricating an implant-supported milled bar overdenture

Abstract

This article describes an alternative impression technique for the fabrication of an implant-supported bar overdenture using the duplicated satisfactory interim denture as a custom tray for the implant-level impression. The primary advantage of this technique is that all the information needed for the definitive prosthesis fabrication is obtained from the interim denture and then transferred to the laboratory in a single appointment. However, this technique may be contraindicated for severely misaligned implants that require extensive reduction of the duplicated denture.
