Rotational path removable partial denture design.

A detailed description of a rotational path of insertion design for removable partial dentures has been presented. By minimizing the use of conventional clasps, this technique offers some advantages. Rotational path designs may minimize adverse periodontal response to a removable partial denture by reducing plaque accumulation and may be applied in esthetically demanding situations. The design concept involves the use of rigid retentive components that gain access to undercut areas through a rotational path of insertion. These rigid components satisfy the basic requirements of conventional direct retained design.
