SPONTANEOUS ERUPTION OF IMPACTED MAXILLARY PRIMARY CANINE AFTER REMOVAL OF ODONTOMA

국문 초록 (Abstract)

복잡 치아종은 치아와 해부학적인 유사성이 없는 법랑질, 상아질, 백악질의 덩어리로 구성되어 있다. 이 병소의 대부분은 증상이 없어 일상적인 방사선 검사나 치아의 맹출 실패의 원인을 감별하기 위한 검사를 통해 발견된다. 복합 치아종은 골 팽창을 보이는 경우가 드물지만, 복잡 치아종은 경미하거나 뚜렷한 골 팽창을 보인다. 복잡 치아종은 거의 영구치와 연관되어 있고 유치와 연관된 경우는 매우 드물다. 이는 보통 하악의 유구치 부위에 발생한다. 본 증례는 상악 유견치의 매복과 연관된 복잡 치아종을 외과적 방법으로 제거하고 자가맹출을 용이하게 하기 위해 치은 하방에 재위치 시켰다. 수술 6개월 후에 상악 유견치가 자가 맹출되었으므로 이를 보고한다.

다국어 초록 (Multilingual Abstract)

Complex odontomas consist of a conglomerate mass of enamel, dentin and cementum which bears no anatomic resemblance to a tooth. The majority of these lesions are completely asymptomatic, being discovered on routine radiographic examination or when films are taken to determine the reason for tooth eruption failure. Compound odontomas seldom cause bony expansion, but complex odontomas often cause slight or even marked bony expansion. Complex odontomas are mostly associated with permanent teeth and very rarely associated with deciduous teeth. They are usually located in the first-or second-molar areas of the mandible. This report presents a case of a patient with impaction of a maxillary primary canine by a complex odontoma in which surgical excision of the lesion was performed. And the primary canine was repositioned right under gingival level for spontaneous erution. Follow-up after six months showed spontaneous eruption ofthe repositioned maxillary primarycanine.
