치아 전위는 치아 이소 맹출의 극단적인 형태로, 인접한 두 치아의 위치가 서로 바뀐 상태로 발육하고 맹출하는 치아 위치이상이다. 상악 견치와 제1소구치의 전위가 가장 흔하게 발견되는데, 이는 다음의 세 가지 방법으로 치료할 수 있다. 첫 번째방법은 치아를 전위된 상태로 배열하는 것이며, 두 번째 방법은 전위된 두 치아 중 한 치아를 발치하고 교정 치료하는 것이다. 세 번째는, 전위된 치아를 원래의 위치로 되돌려 배열하는 방법이다. 치료 방법을 결정할 때에는 기능, 심미, 지지 치주 조직의 손상 가능성, 치료 기간, 환자의 협조도, 환자의 심미적 요구도를고려하여야 한다. 본 증례는 견치와 제1소구치 간의 전위가 일어난 환자 세 명의 교정 치료에 관한 것으로, 각기 다른 치료방법을 사용하여 양호한 결과를 얻었기에 이에 보고하는 바이다.
Abstract
Transposition is a unique and extreme form of ectopic eruption where a tooth develops and erupts in a position,normally occupied by an adjacent tooth. Generally, three treatment options are available when the maxillary canine and first premolar are transposed. In the first treatment option, the transposed position of the teeth can be maintained such that the first premolaris moved to the position of the canine. Second, extraction of the maxillary first premolar can be considered. Third, the position of the transposed teeth can be corrected such that their normal positions in the arch arerestored. Factors that should be considered in treatment modality decision include function, occlusion, periodontalsupport, treatment time, patient cooperation, and esthetic demands. This report describes cases of maxillarycanine-premolar transposition treated with each of the three aforementioned treatment options. In the first case,transposed teeth were arranged in their transposed position. The second case was an extraction case. In thethird case, orthodontic treatment and surgical repositioning were conducted.
