This document discusses removable partial dentures. It begins by outlining the indications for removable partial dentures, including when the abutment teeth are not suitable for fixed bridges due to periodontal issues, extensive bone loss, or economic considerations. It then covers classifications for partially edentulous arches, including whether the denture is tooth-borne, tissue-borne, or a combination. Kennedy's classification system categorizes cases based on the location of edentulous spans. The document concludes with the component parts of removable partial dentures.
