EPA 4C: Partial Edentulous Removable Partial Dentures (RPD) Design

Partial Edentulous Removable Partial Dentures (RPD) Design	Meets Expectations of the Graduate	Progressing	Below Expectations	Critical Error

Neatness	Lines neat and well defined Appropriate colors used	Some lines ill-defined or incomplete Some colors inappropriate	Major connector of RPD framework decidedly ill defined Finish lines ill defined Corrected lines not removed completely	Lines too ill defined to read Components drawn grossly out of proportion to wax pattern dimensions Failure to tripod cast
Major Connector	Properly designed Proper dimensions, located correctly with respect to gingival margins and floor of mouth or palate	Minor deviations from ideal design on palate Minor impingement on gingival margins, floor of mouth Minor deviations from ideal design on palate	Significant deviations from ideal design Large areas impinging on gingival margins or floor of mouth Major deviations from ideal design on palate Missing finish line	Gross design errors making major connector unusable No major connector drawn
Minor Connector	Properly designed Appropriate dimensions	Design not ideal but reasonable Dimensions somewhat over or under sized	Unnecessary connectors present in design Dimensions obviously over or undersized Missing components such as stops, gingival feet, physical retainer (meshwork)	Gross design errors making minor connector unusable No minor connector drawn
Clasp Design	Proper clasp design for Kennedy Classification of cast All components present and undercuts properly indicated for reduction or block out	Clasp design has components in areas of undercut without indication of block out or tooth reduction Clasp design not ideal but would not potentially harm tooth or tissue	Clasp design would not provide ideal retention Clasp design missing component such as reciprocal component Inappropriate amount of retentive undercut No soft tissue survey line	Clasp design inappropriate for Kennedy classification of cast Clasp retentive element placed in area without Clasp designed in area of significant tissue undercut Fails to mark retentive undercut
