Abstract

Maxillary canine impaction is an anomaly often encountered in children. Although it has been reported that the incidence of palatally impacted canines is higher than that of labially impacted ones, it has been found that labial impaction of canines is more common than palatal impaction in Asian populations. In the cases presented here, maxillary canines were guided normally after rapid palatal expansion, followed by modification of root angulation of neighboring lateral incisors in 8-10-year-old children who had maxillary canines suspected of labial impaction. Consequently, the method of modifying the root angulation of the maxillary lateral incisor, combined with rapid palatal expansion, is effective in preventing impaction of an ectopically erupting maxillary canine without resorting to surgical methods.

상악 견치 매복은 소아 청소년기 환자들에게서 흔하게 발견되는 문제이다. 일반적으로 구개측 매복이 순측 매복 보다 더 흔한 것으로 알려져 있지만 서양에서는 오히려 순측 매복이 더 많은 것으로 보고되고 있다. 본 보고에서는 파노라마 방사선 사진상 상악 견치의 순측매복이 의심되는 8-10세의 혼합치열기 아동을 대상으로 급속 구개확장(rapid palatal expansion)을 시행하였으며, 이를 통하여 상악 측절치의 근원심 치근각도를 조절하여 매복 가능성이 있는 견치의 정상맹출을 유도할 수 있었기에 보고하는 바이다.
