Retreatment of fractured implant overdenture due to long-term maintenance failure / 대한치과보철학회지

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.
