초록
소수의 잔존치가 편측으로 남아 있을 때 전통적인 가철성 국소의치를 제작하는 경우, 기능시 잔존 치아를 연결한 축을 중심으로 의치의 회전이 발생하며 부분 무치악 부분이 긴 경우 점막 지지 비중이 증가되어 지대치에 대한 유지와 안정을 얻기 어렵다. 이런 의치의 움직임은 의치의 유지와 안정을 감소시키며 지대치에 과도한 힘을 가하게 되고 치주 건강에 좋지 않은 영향을 미치게 된다. 따라서 추가적인 임플란트를 식립하여 부가적인 유지와 안정을 얻는 국소의치의 치료가 좋은 선택이 될 수 있다. 잔존치와 대칭적인 위치에 임플란트를 식립 후 임플란트 지지 서베이드 금관을 제작하여 국소의치 삽입로와 각종 구성 요소를 받아들일 수 있는 설계로 제작하여 좋은 임상 결과를 얻었기에 보고하는 바이다.
Abstract
When making conventional removable partial denture for the remaining teeth where the remaining teeth are only on one side, rotation of the denture occurs -in function- on the axis of the connected remaining teeth. If the edentulous portion is long, it becomes harder to obtain retention and stability for the abutment as the importance of the mucous membrane support is elevated. Such movements of denture decrease denture retention and stability, put excessive stress on the abutment, and give bad influence on periodontal health. Therefore, additional implant placement can be of a good choice in gaining additional retention and stability for partial denture. Thus hereby we report this clinical case as successful results were obtained by placing implants symmetrical to the remaining teeth and putting implant-supported surveyed crowns on the implants, allowing the partial denture to be designed to accept varying components and to have suitable path of insertion.
