Telescopic crown-retained removable partial dentures: review and case report

Double crown-retained prostheses have been successfully used in partially edentulous patients. This type of retainer provides guidance, support, and protection from dislodging movement, and it transfers bite forces along the long axis of the abutment teeth. Furthermore, the denture can easily be retrieved when an abutment needs to be extracted. By modifying the preparation and veneering technique, overcontour of the double crowns can be minimized. Using custom-made all-ceramic crowns as prosthesis teeth and individualizing the denture base, esthetics can be improved. Longitudinal follow-up studies of 5 to 10 years report that conical crown-retained partial dentures have a lower failure rate compared to those retained with clasps or precision attachments. In a case report, clinical and technical aspects of constructing telescopic crown-retained removable partial dentures are discussed.
