초록

치아매복이란 물리적인 장벽으로 치아맹출에 장애가 발생하는 것으로, 정상 맹출 시기까지 치아가 맹출하지 못하는 상태를 말하며, 영구치열기에서 주로 관찰되고, 유치열기에서는 드물다. 치아매복은 전신적 그리고 국소적인 요인에 의하여 일어나고, 치아종에 의한 매복이 자주 발생하는 것으로 보고되었으며, 치아종에 의한 매복 또한 대부분 영구치열기에 나타나고, 유치열기에서는 드물게 발생한다. 이 증례는 하악 좌측 제2유구치의 맹출지연을 주소로 내원한 4세 4개월 된 여아에서, 임상 및 방사선학적 검사 결과 매복된 하악 좌측 제2유구치와 제1대구치 교합면 상방에서 치아종을 관찰할 수 있었으며, 하악 좌측 제2유구치는 치아종에 의해 하악 제1대구치 방향으로 원심경사 되어 있었다. 이에 저자들은 치아종을 제거한 후 매복된 하악 좌측 제2유구치를 교정적으로 견인하고 맹출을 유도하여, 양호한 교합 관계를 얻었기에 이를 보고하는 바이다.

Tooth impaction refers to situations where a tooth fails to erupt due to mechanical blocking and remains unerupted beyond the normal time of eruption. It is commonly found in permanent dentition, but rarely in deciduous dentition. Tooth impaction is caused by systemic or local factors, and most common etiology is odontoma. Odontoma is also commonly found in permanent dentition, and rarely in deciduous dentition. We are presenting case of 4 year and 4 month year old girl, who had impacted and disto-angulated lower left deciduous second molar due to odontoma. We removed odontoma and performed orthodontic traction of impacted lower left deciduous second molar. Then, the impacted primary molar was erupted and acceptable occlusion was obtained.
