초록
외상에 의한 치아의 함입은 치아가 치조골 방향으로 변위되어 있는 상태이다. 함입성 탈구는 다른 유형의 탈구성 손상에 비하여 드물게 발생하고, 낙상에 의한 경우가 많으며, 소녀보다는 소년에서 호발하는 것으로 보고되었다. 치아가 함입되었을 때, 치수괴사나 유착, 치근흡수, 근관폐쇄, 변연골 상실 등과 같은 합병증이 발생할 수 있으며, 치아 경조직과 치아 지지조직 등의 손상이 동반되는 경우가 흔하므로, 예후를 예측하고 정확한 진단 및 치료계획을 수립하는데 어려움이 있다. 함입된 치아의 치료는 자발적으로 재맹출하기를 기다리거나, 교정적 견인 또는 외과적으로 재위치 시키는 방법이있다. 이 증례는 외상으로 인하여 상악 좌측 중절치가 함입되었다는 주소로 내원한 6세 7개월 된 여아에서, 함입된 치아의 자발적인 맹출을 기대하였으나 맹출이 되지 않아서, 교정적으로 견인하여 맹출시킨 경우로 양호한 결과를 얻었기에 이를 보고하는 바이다.
Abstract
Traumatic intrusion is a type of injury that involves axial displacement of a tooth toward the alveolar bone. Its occurance is relatively rare compared to other types of luxation in permanent dentition. It is more commonin boys than in girls, and most common etiology of intrusion is fallen down. Various complication may occur followingtraumatic intrusion, such as pulp necrosis, root resorption, pulp obliteration and marginal bone loss. Inaddition, traumatic intrusion is commonly combined with hard or soft tissue injuries. Therefore, it is difficult toestablish proper treatment plan. Choice of treatment for an intruded tooth by trauma include waiting for spontaneousre-eruption, orthodontic repositioning, and surgical repositioning. In this case, we repositioned the intruded central incisor using orthodontic traction, in a six-year old girl,which failed to re-erupt spontaneously.
