초록

임플란트 수복물의 기계적 실패 요인들 중 가장 잦은 빈도를 보이는 것은 지대주 나사의 풀림이나 파절로 알려져 있다. 이렇게 지대주나, 나사가 파절된 경우 그 잔사들을 임플란트 고정체의 손상 없이 완전히 제거해야만 한다. 때로는 잔사들을 제거할 수 없는 경우나 제거 과정에서 고정체와 나사를 연결하는 부위가 손상되어 임플란트를 지속하여 사용할 수 없는 경우가 발생하여 임상가를 곤란하게 만드는 경우가 있다. 본 증례보고에서는 각기 다른 세가지 임상상황에서 임플란트 고정체의 손상 없이 성공적으로 파절편을 제거한 사례들을 보고하고 나사가 파절된 임상상황에서 대처할 수 있는 방법들에 대해 고찰해 보고자 한다.

Screw loosening and screw fracture of abutment is one of most frequent mechanical complications in implant restoration. Fractured fragments in implant restoration like abutment and screw should be completely removed and the procedure needs minimal damage to the fixture of implant. In some cases, it could fail to remove fractured fragments and cause a lot of damage to the fixture of implant. These situations could render implant unusable at the worst. This article describes three different situations and simple techniques for successful removal of fractured fragments without damage of implants. The procedures used are described in this clinical report.
