Trauma to the abutment teeth or gums can occur from pressure or movement of the partial. Maxillary removable partial denture (RPD) with a cosmetic circumferential clasp for premolars with occlusal rest (CCCPO = C3PO) clasp on the premolar. 1 This article will provide an 19-year retrospective reflection on the R2D2 clasp, and present examples of clinical applications for this design. The best partial dentures available are the ones that we have listed. Removable partial denture must also be stable against rotational movements through the use of rigid connector and indirect retainers. The use of aesthetic flexible removable partial dentures (FRPD) has sky-rocketed over the last several years (Figure 1).
