견치의 맹출은 영구치열의 이행에 중요하다. 견치 매복의 원인으로 유치의 조기 상실 또는 만기 잔존, 신생물 등이 있으며측절치 이상이 상악 견치 매복을 야기할 수 있다. 치료되지 않은 매복 견치는 부정교합, 낭종 등을 야기하고 교정치료를 복잡하게 한다. 이 연구의 목적은 매복된 상악 견치의 위치를 조사하여 치료 및 합병증과의 관계를 규명하는 것이다. 상악 견치매복으로 진단된 89명의 파노라마사진과 전산화단층영상을 사용하여 견치의 위치를 평가하였다. 시행된 치료와 합병증과의상관관계에 대해 조사하였다. 가장 흔한 매복 위치는 치열궁 영역이었고 협측과 구개측 순이었다. 교정적 견인이 가장 빈번히 선택되었으며 합병증으로는 인접치를 변위시키는 경우가 가장 흔했다. 협측에 매복 시 변위를 일으키는 경향이 높았고,협측에 매복될수록 교정적 견인이 덜 시행되었다. 중절치 근심에 매복 시 치근 흡수를 일으키는 경향이 더 높았다. 그러므로상악 견치에 대한 검진을 통해 조기 진단과 적절한 치료의 시행이 필요하다.
Abstract
Normal eruption of the canine is important for the transition to the permanent dentition. Etiologies, including premature loss or delayed retention of deciduous teeth, neoplasm and abnormality of lateral incisor can cause impaction of the maxillary canine. Untreated canine impaction can result in malocclusion, cyst formation and obstacles in orthodontic treatment. The aim of this study is to evaluate location of the impacted maxillary canine and to identify correlation between location and management of the impaction including complications. Using panoramic radiographs and CBCT scan, images of 89 children diagnosed with impaction of the maxillary canine,location of impacted canines was evaluated. The choice of treatment and complications were investigated to identify correlation. Results show that the most commonly impacted location of the maxillary canine was in the mid-alveolar area, followed by buccal side and palatal side. Orthodontic traction was selected more frequently than the other treatments. As complications, displacement of adjacent tooth was occurred most frequently. Buccally impacted canines showed increased tendency towards displacement. The more buccally the canine was impacted, the less orthodontic traction was chosen as the treatment. The canine impacted mesially to the central incisor showed increased tendency to occur root resorption. Therefore, early diagnosis by periodic examination,appropriate treatment and intervention is required.
