초록

피개 의치는 의치의 안정과 유지력 증가라는 장점을 갖지만 지대치가 우식 또는 치주질환에 이환되기 쉬우며 의치의 두께가 얇아짐으로써 의치가 파절되기 쉽다는 단점도 갖고 있다. 자성 어태치먼트 피개 의치는 수직적 유지력은 크지만 수평적 유지력은 작으므로 지대치나 임플란트에 덜 위해한 힘을 가하며, 다른 기계적 유지장치에 비해 마모나 파손 등이 적다는 장점이 있다. 피개 의치에서 나타나는 의치의 파절은 의치상의 두께가 얇아져서 발생하기도 하지만, 연조직과 경조직, 임플란트와 자연치의 압하량 차이로 인해 발생하기도 한다. 이를 보상하기 위해 silicone ball이 자석 안에 삽입되어있는 자성 어태치먼트가 개발되었으며, 이를 이용해 피개 의치를 제작한 증례에서 우수한 결과가 나타나 보고하고자 한다.

Overdenture has the advantage of improving the stability and retention of the denture but the abutment may be easily affected by caries or periodontal disease and the thin denture can be easily broken. The magnetic attachment overdenture has a high vertical retention but a low horizontal retention, thus, exerting a less disruptive force to the abutment or implant and shows less abrasion or damage compared to other mechanical retainers. Denture fractures in overdenture is caused by the thin denture base as the attachment is inserted, but it may also be caused by the difference in detrusion between soft tissue and hard tissue, and between an implant and a natural tooth. To compensate this shortcoming, a magnetic attachment with a silicone ball inserted in the magnet was developed as we report a successful case using this specific type of magnetic attachment overdenture.
