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.

임플란트 피개의치에서 치주적, 보철적 유지관리는 보철물과 임플란트의 장기적 성공에 매우 중요한 요인이다. 유지관리의 실패는 임플란트 주위 골소실 및 보철물이나 구성품의 파절 및 마모로 인해 보철적 실패를 유발할 수 있다. 이 증례에서는 유지관리 실패로 파절된 임플란트 피개의치의 재치료를 위해 기존의 골드 milled bar를 코발트 크롬 milled bar로 외형에 방해되지 않는 형태로 재제작하였고, 하악의 기존 고정성보철은 임플란트 주변 골흡수와 환자의 전신적 문제로 인해 전략적으로 임플란트를 선택하여 두 개의 임플란트에 CM LOC을 연결하여 임플란트 피개의치를 제작하여 재수복하였다. 결과적으로 환자의 위생관리를 수월하게 하는 디자인의, 기능적 심미적으로 장기간 유지관리에 유리한 보철물로 수복하였고 정기적인 유지관리를 시행하였다.
