Indexing procedures for converting removable partial dentures after extractions while the patient retains the prosthesis

A new indexing procedure is described for the conversion of removable partial dentures when extraction of additional teeth is planned. Advantages and disadvantages of the indexing procedure are reviewed and compared with traditional treatment options. The new procedure facilitates the use of dental laboratory expertise and facilities and allows the patient to retain the prosthesis throughout the process. A component that includes teeth, denture base segments, and wire or cast clasps is created by the laboratory and attached by the dentist during the extraction visit as a simple denture repair procedure. The procedure can also be used to convert an existing partial denture to an immediate complete denture. Required clinical and laboratory procedures are described.
