Abstract

For individuals with cleft lip and palate, the removable partial dentures (RPDs) have been an important treatment option. Some modifications from conventional prosthetic treatment may be necessary to achieve satisfactory functional and esthetic results in cleft patients. In case of cleft palate patient with periodontally compromised and only posterior few remaining teeth, removable partial prosthesis connected to telescopic crown can be the alternative treatment option. When connected to the RPD, telescopic crowns increase the prosthetic stability and retention, optimize favorable force transmission to the long dental axis, and improve esthetics. And the cross arch stabilization of double crown denture helps to stabilize both divided maxillary ridges in CLP patient. This case present one adult CLP patient using an RPD connected with hybrid telescopic crowns with friction pins to improve not only retention and stability but also aesthetics.
