Abstract

Treatment options for impacted permanent molars include orthodontic traction, surgical repositioning, transplantation, and extraction of the impacted teeth. Orthodontic traction is recommended because it is the most conservative method. However, it has limitations, such as loss of tooth anchorage. In an effort to overcome these limitations, skeletal anchorage devices tailored for orthodontic use were developed. In this case report, 3 patients were diagnosed with impacted permanent molars. The impacted teeth of these patients were surgically exposed, the orthodontic devices were attached, and the skeletal anchorage devices were implanted for the successful traction of the impacted teeth.

매복된 영구 대구치의 치료 방법으로는 교정적 견인, 외과적 재위치, 자가치아이식, 매복치아의 발치 등이 있으며, 이 중 가장 보존적인 방법인 교정적 견인이 권장된다. 그러나 매복된 영구 대구치의 교정적 견인 시 치아를 이용한 고정원의 확보는 고정원의 상실을 동반할 수 있으며, 이러한 한계를 극복하기 위한 노력의 일환으로 골성 고정원 장치가 개발되었다. 본 증례 보고에서는 영구 대구치가 맹출하지 않는다는 주소로 본원에 내원한 3명의 환자에서 매복치아를 외과적으로 노출하여 교정 장치를 부착하고 골성 고정원 장치를 식립하여 성공적으로 견인하였음을 보고하는 바이다.
