장기간의 유지관리 실패로 인해 파절된 임플란트 피개의치 재수복 증례 = Retreatment of fractured implant overdenture due to long-term maintenance failure

다국어 초록 (Multilingual Abstract)

Periodontal and prosthodontic maintenance of implant overdenture is a very important factor for the long term success of the prosthesis and implants. Failure of maintenance can lead to prosthetic failure due to peri-implant bone loss and fracture and wear of the prosthesis or components. In this case, the existing gold milled bars were reconstructed with cobalt chrome milled bar in a manner that does not interfere with the external shape for the retreatment of fractured implant overdenture by maintenance failure. Two implants of mandible were selected strategically and the CM LOC attachments were connected to the two implants, and implant overdentures were fabricated. As a result, prosthesis with a functional and esthetic design that facilitates good hygiene management of the patient was delivered, which is advantageous for long term maintenance, and regular check-ups were scheduled for proper maintenance.
