Z. Benur et al., DESIGNING CLASPS FOR THE ASYMMETRIC DISTAL-EXTENSION REMOVABLE PARTIAL DENTURE, The International journal of prosthodontics, 9(4), 1996, pp. 374-378
Retentive clasp components can be created to minimize torquing forces
on abutment teeth incorporated in the support and retention of bilater
al distal extension removable partial dentures. Functional movement of
the combined tooth-mucosa-borne prosthesis about the axis of rotation
necessitates consideration of retentive element design modifications,
particularly as they relate to bilateral asymmetric distal extension
situations.
