- To provide preplanned rests, axial surfaces, guiding planes, and retentive areas to support and retain an extracoronal direct retainer clasp of a removable partial denture.
- Proximal Guiding Plane — straight occlusocervically; curved buccolingually; at least two thirds of the proximal surfaces; parallel to the selected path of insertion.
- When a complete crown is constructed for a completely tooth-borne removable partial denture, it is possible to alter the crown contour with a ledge that guiding planes, rests. and reciprocal clasp arms become extensiorls of the natural contour of the crown.
