Abstract
An RPD framework includes five components: The major connector, minor connectors, rests, direct retainers, and indirect retainers (in distal extension RPDs). A major connector combines all other components of an RPD so that the partial denture acts as one unit. Thus, functional loads can be distributed to all abutment teeth, and cross-arch stabilization can be provided. In addition, in distal extension RPDs, forces can be distributed between both the abutment teeth and the mucosa by unification of the direct retainers with the denture base.
