초록

이 연구는 파노라마 방사선 영상과 Cone-Beam Computed Tomography (CBCT)를 이용하여 상악 매복 견치의 견인 치료기간에 영향을 미치는 요인을 알아보고 견인 기간을 예측하고자 하였다. 2012년 1월부터 2020년 12월까지 아주대학교 치과병원에 내원한 환자들 중 상악 견치의 매복으로 진단받아 외과적, 교정적 개입을 통한 견인 치료를 시행 받고 상악 매복 견치의 맹출까지 치료받은 만 8세 이상 만 18세 이하 환자 73명(93개의 상악 매복 견치)의 의무기록지와 방사선학적 영상을 후향적으로 분석하였다. 단계적 다중회귀분석 결과 교합평면에서 상악 매복 견치 교두정까지의 거리, 근-원심과 협-구개 위치, 환자의 나이 그리고 급속구개확장장치의 사용 유무는 견인 치료기간을 예측하는 데 통계적으로 유의미한 요인이었으며, 매복 견치의 치축이 교합평면과 이루는 각과 편측성/양측성 매복 양상은 견인 기간과 유의미한 상관관계를 보였다. 견치의 낮은 매복 깊이, 견치 교두정의 근-원심 위치가 측절치 또는 견치 영역, 협-구개 위치가 협측 또는 중앙에 위치하고, 치료시작 시 환자의 어린 나이 그리고 구개 확장 장치의 사용이 상악 매복 견치의 견인 기간을 짧게 예측하는 데 도움을 줄 수 있을 것이다.

The aim of this study was to identify factors that affect the treatment duration and to predict the duration of forced eruption in impacted maxillary canines using panoramic radiographs and cone-beam computed tomography. This retrospective study was performed by reviewing medical records and radiographs of 73 patients (93 impacted maxillary canines) from the age of 8 to 18 years who were treated with surgical and orthodontic interventions on impacted maxillary canines from January 2012 to December 2020 in Ajou University Dental Hospital. Stepwise multiple regression analysis showed that the distance between the canine cusp tip and the occlusal plane, mesio-distal location, bucco-palatal location, patient's age, and use of rapid palatal expansion are significant factors with regard to the duration of forced eruption. There was a statistically significant correlation of the treatment duration with the angulation between the axis of the canine and the occlusal plane and unilateral or bilateral impaction. It can be concluded that the duration of forced eruption in impacted maxillary canines could be shorter when the impacted canine is closer to the occlusal plane and located in the lateral incisor or canine area, buccal or middle, the patient is younger and uses rapid palatal expansion.
