A removable partial denture (RPD), as the name implies, is a prosthodontic restoration that supplies teeth and associated structures to a partially toothless mouth and that can be removed and inserted by the patient. In general, an RPD is made from a combination of several common dental materials. The basic substructure or framework of an RPD is fabricated from one of several commercially available dental alloys but most commonly chromium-cobalt. RPD’s gain all or part of their support from the remaining natural teeth (or dental implants). If all of the support is from teeth it is classified as a tooth-borne (supported) RPD. Others derive their support from both the teeth and the residual ridge tissues and are termed tooth-tissue-borne (supported) RPD‘s (or distal extension or distal saddle). Between these two extremes of support are a range of RPD‘s that derive a varying amount of support from both the natural teeth and associated residual ridges.
