A 78-year-old female patient presented with implant failure in the maxillary and mandibular anterior areas due to medication-related osteonecrosis of the jaw. Implant-supported fixed dental prosthesis (FDP) in the maxilla and mandible were removed, and implants with osteomyelitis were removed in the anterior area (three implants in the maxilla and two implants in the mandible). After the healing period, the maxillary anterior area was recovered with 6-unit implant-supported FDP, and the mandible was reconstructed using an implant-supported double-crown-retained removable denture with friction pins. The patient was satisfied with the functionality and maintenance of the new prostheses.
