Fabricating crowns that fit both an implant and an existing removable partial denture.

Abstract

Fabricating a crown to fit both a tooth and an existing removable partial denture (RPD) using many different techniques has been described. However, in the event of abutment loss, information regarding the clinical and laboratory steps used to fabricate a crown that fits both an implant and an RPD is lacking. This report describes the use of either an impression coping or an interim abutment attached to the implant to which a composite resin interim restoration material is flowed and the RPD then seated to form a resin pattern of the required crown form. The process allows the implant crown to be made without retaining the patient's RPD during crown fabrication.
