Extracoronal direct retainers for distal extension removable partial dentures

Abstract

Distal-extension removable partial dentures have always posed a challenging situation to the clinician and in such cases the strategic positioning of the direct retainers would ensure the long-term success of the prosthesis. Different direct retainer designs have been discussed by various authors in the literature. This paper highlights the extracoronal direct retainers, which can be used in the successful prosthodontic rehabilitation of distally edentulous arches with a removable partial denture.
