Classification of removable partial denture
Applegate’s modification (1960): include 2 or more additional groups based on the condition of the abutment:
Class V: a edentulous area bounded anteriorly and posteriorly by natural teeth but in which the anterior abutment (e.g. LI) is not suitable for support. It is basically a class III situation for the anterior abutment cannot be used for any support.
Class VI: edentulous area in which the teeth adj.to the space are capable of total support of the required prosthesis. This denture hardly requires any tissue support. Most of the RPDs are tooth tissue supported. Hence this condition is classified as a separate group.
