An Akers' clasp is the classic direct retainer for removable partial dentures. [1] Named after its inventor, Polk E. Akers, this suprabulge clasp consists of a rest, a guide plate, a retentive arm and a reciprocal arm. Akers' clasps, as a rule, face away from an edentulous area. Should they face the edentulous area, they are termed reverse ...
A removable partial denture (RPD) is a denture for a partially edentulous patient who desires to have replacement teeth for functional or aesthetic reasons and who cannot have a bridge (a fixed partial denture) for any reason, such as a lack of required teeth to serve as support for a bridge (i.e. distal abutments) or financial limitations.

The teeth used to support the bridge are called abutments. A bridge may also refer to a single-piece multiple-unit fixed partial denture (numerous single-unit crowns either cast or fused together). The part of the bridge which replaces a missing tooth and attaches to the abutments is known as a "pontic".
