ABSTRACT:
Claspless removable partial dentures have a metal bar that connects to a metal framework to which is attached metal occlusal rests. The metal occlusal rests fit into prepared slots in the natural teeth on either side of the edentulous area. This metal framework supports the resilient dental material that bonds the denture teeth in their position and is bonded to the metal framework. This resilient dental material extends into the inward curve of the natural teeth on either side of the edentulous area, and by sliding into the inward curve, the partial is held in position. The metal framework is left open beneath the denture teeth so that each denture tooth can move into the resilient dental material, which then absorbs the force of mastication.
