Tooth-supported removable partial dentures, using rotational paths of placement, are described. Retention is obtained when a minor connector rotates into a proximal undercut. It is maintained in intimate contact with the tooth surface by its partial denture rest, other components of the prosthesis, and clasps located away from the path of rotation. Although conventional clasps are not totally eliminated, they may be confined to posterior abutments where esthetics are usually not affected. Factors that influence the practicality of the rotational path of placement include patient acceptance and coordination, the presence of proximal undercuts, the location and number of edentulous areas, and the arch form.
