초록

하악 제1대구치 맹출장애의 빈도는 전체 인구의 0.01%로 드물게 나타나며, 발생 원인과 발견 연령 등에 따라 매복, 일차적 만기잔존(primary retention), 이차적 만기잔존(secondary retention) 등으로 분류된다. 치료로는 주기적 관찰, 외과적 노출술, 외과적 노출술 후 교정적 견인술, 탈구를 동반한 교정적 견인술, 외과적 재위치술, 발치 등의 방법을 적용할 수 있다. 이 증례보고는 각각 매복, 일차적 만기잔존, 그리고 이차적 만기잔존으로 진단된 5명의 환자들에서 다양한 치료방법을 이용하여 하악 제1대구치를 성공적으로 교합유도한 증례들을 보여준다. 맹출장애를 갖는 하악 제1대구치는 치아의 평균적인 맹출시기에 임상 및 방사선검사를 통해 매복, 일차적 만기잔존, 그리고 이차적 만기잔존으로 적절하게 진단내려질 수 있으며, 치아의 맹출 정도, 대합치와 인접치와의 관계, 환자의 연령, 협조도, 경제적 상황을 종합적으로 고려하여 치료되어야 한다.

With a prevalence rate of 0.01%, the presence of eruption disturbances of mandibular first molar has rarely been in populations. Eruption disturbances of permanent molars have been usually manifested as impaction, primary retention, and secondary retention. The treatments of eruption disturbances are carried out by: periodic observation; surgical exposure; forced eruption after surgical exposure; forced eruption with luxation; surgical repositioning; and extraction. This case report show successfully erupted mandibular first molars by various treatment methods on five patients diagnosed with impaction, primary retention, and secondary retention, respectively. Eruption disturbances of the mandibular first molar can be properly diagnosed with impaction, primary retention, and secondary retention by clinical and radiographic examination at normal eruption time of the mandibular first molar. The treatment should be done synthetically, considering eruption state of affected tooth, the relationship between the affected tooth and the adjacent or opposite tooth, the patient's age, treatment compliance, and economic state.
