    Study Notes

    RPD Classification

    • RPD classification methods vary based on factors such as location of edentulous area, type of support, and denture extent.

    Applegate's Rules

    • Rule 7: The extent of modification is not considered, only the number of additional edentulous areas.
    • Rule 8: There are no modification areas in Class IV arches; if a posterior edentulous area exists beside an anterior one, the former determines the class, and the anterior area is a modification.

    RPD Components

    • Denture base: carries the teeth
    • Connectors:
      • Major connector
      • Minor connector
    • Retainers:
      • Direct retainer (clasp or attachment)
      • Indirect retainer

    RPD Construction Steps

    Clinical Steps

      1. History taking, examination, and diagnosis
      1. Primary impression in a suitable stock tray

    Laboratory Steps

      1. Pouring the impression in dental stone to construct the diagnostic cast
    • Diagnostic cast used for:
      • Surveying
      • Final design drawing
      • Duplicating to refractory cast
      • Final construction of the denture
    • Diagnostic cast may be used for special tray construction

    Master Cast

    • Made after mouth preparation
    • Constructed from the diagnostic impression or primary impression
