초록

치아 유착은 손상에 의해서 치조골과 상아질 또는 백악질이 유합된 상태로, 외상, 내분비 질환, 쇄골 두개 이형성증등의 선천성 기형 또는 원인 불명의 맹출 장애 등이 원인으로 알려져 있다. 유착 치아로 인해 인접치의 경사, 공간 상실 및 대합치의 정출이 나타날 수 있고, 성장기 아동에서 유착이 발생한 경우 치조골의 발육 부전을 야기할 수 있으며, 특히 상악 전치부에 이환되면 심각한 심미적 문제를 초래하게 된다. 따라서 유착이 의심되면, 병력 청취와 타진 및 방사선 사진 상의 치근막 공간 평가, 또는 가장 직접적이고 확실한 방법인 교정력을 직접 적용해 보는 방법을 통해 정확한 진단을 내려야 한다. 통상적으로 치료는 유착된 치아의 발거, 자가 치아이식, 외과적 탈구, 수술적 방법을 통한 재위치술 등을 선택하게 된다. 그 중, 수술적 방법을 통한 재위치술은 유착치의 발거 시 상당한 골소실이 예상될 때 시행할 수 있으며, 단일치아 골절단술과 치조골 신장술이 대표적이다. 본 보고에서는 이러한 수술적 방법으로 상악 전치부의 유착치를 심미적으로 치료한 증례를 소개하고자 한다.

Tooth anklylosis is defined as the adhesion state of alveolar bone to dentin or cementum. Trauma, disturbed metabolic disease, and congenital disease have been given as etiologic factors. Complications of tooth ankylosis are tipping of the neighboring teeth, space loss, and supraeruption of the opposing teeth. Particularly if dental ankylosis occurs in maxillary incisors of a growing child, the ankylosed tooth can not move vertically with subsequent disturbance in vertical growth of the alveolar process. With an appropriate treatment approach, an esthetic condition must be achieved especially in the maxillary anterior region. In this report, two cases are presented which were treated by the surgical repositioning method. One is treated by alveolar bone distraction osteogenesis which used a tooth-borne type distraction device and the other by single tooth osteotomy.
