Abstract

Several types of attachments have been used for implant supported and/or retained overdentures. Locator is one of the stud type attachments and it has been generally used. However, the colored matrix is resilient and vulnerable to wear, so frequent post-insertion maintenance is needed. To solve this problem, it is necessary to introduce innovative attachment system. Overdentures using Air Gap attachment (AGA) has improved masticatory function and facial esthetics. AGA is made of metal, so it could be more resistant to wear or friction than the other resilient attachments. Nevertheless, AGA plays a role in stress breakers because it allows movement during denture movement with predetermined gap. In addition, both pre-existing implants and natural teeth were successfully used for connection of AGA. AGA could replace other unsplinted type of attachments. Overdentures using AGA could provide satisfactory result in terms of function, esthetics and retention. However, long term follow up is needed.

임플란트 지지 혹은 유지 피개 의치에서 다양한 종류의 유지 장치가 사용되어 왔다. Locator는 stud type의 유지 장치 중 하나로 널리 사용되어 왔으나 그 matrix는 탄성을 가지며 쉽게 마모되는 경향이 있어, 보철물 장착 후 빈번한 유지 관리가 필요하다. 이러한 문제점을 해결하기 위하여 새로운 유지 장치의 도입이 요구되었다. 본 증례에서는 새로운 ball type 유지 장치인 Air Gap attachment (AGA)를 이용한 피개의치로 수복한 증례를 보고하고자 한다. AGA는 금속으로 제작되어 다른 탄성 유지 장치에 비해 마모 저항성이 높다. 그럼에도 불구하고, 의치가 움직일 때 일정한 간극을 통해 움직임을 허용함으로써 stress breaker로의 역할이 가능하도록 하였다. 또한 기존에 식립된 임플란트와 자연치 모두 AGA와 연결이 용이하여 다른 unsplinted type의 유지 장치를 대체할 수 있다. AGA를 이용한 피개의치에서 기능, 심미 및 유지력의 면에서 만족할 만한 결과를 얻어 이를 보고하는 바이며, 장기간의 경과 관찰을 요한다.
