Three strategies of implant placement as an abutment for combined tooth-implant-supported double crown removable partial dentures: A clinical report of three patients up to 18 years.

Abstract

Double crown removable partial dentures (RPDs) are suitable treatment options for patients with a significantly reduced dentition. The prognosis for these prostheses is greatly influenced by the number, position, and distribution of the abutment teeth. If the remaining natural teeth are unfavorably positioned, placing implants in strategic positions may enhance the long-term prognosis of the prosthesis. In this clinical report, 3 patients with a reduced dentition were treated with combined tooth-implant-supported double crown RPDs using a gold electroforming system. During an up to 18-year follow-up, the implants and natural abutment teeth showed no pathologic signs. By following the 3 strategies for placing supplementary implants outlined in this clinical report, the combined tooth-implant-supported double crown RPD using a gold electroforming system can be highly recommended.
