  • Title: New Clasp Assembly for Distal Extension Removable Partial Dentures: The Reverse RPA Clasp.
    Author: Hakkoum MA.
    Journal: J Prosthodont; 2016 Jul; 25(5):411-3. PubMed ID: 26102601.
    Abstract:
    Several clasp types are used in distal extension removable partial dentures. In some cases the terminal abutments have only distal retentive undercuts that can be occupied by bar clasps; however, bar clasps may be contraindicated with no suitable alternative. This article presents a reasonable solution by introducing a new clasp design as a modification to the well-known RPA clasp. The design includes a mesial rest, proximal plate, and buccal retentive arm arising from the rest and extending to reach the distal retentive undercut.
