초록
영구치의 매복은 다양한 빈도로 보고되며, 인구 집단의 약 5.6~18.8%에서 발생한다. 그 중에서 하악 제2대구치의 맹출장애 빈도는 약 0.06%, 하악 제1대구치는 약 0.01%로 매우 드물게 나타난다. 영구 대구치는 기능적으로 저작을 위한 중요한교합적 지지를 제공하며 안면의 조화로운 성장발육에 중요한 역할을 담당한다. 영구 대구치의 매복시 발생되는 문제점으로는구치부의 개방교합과 대합치의 정출, 인접치의 치근흡수와 기울어짐, 낭종의 형성, 심할 경우 하안면고경의 감소 등 여러 가지 문제점이 유발될 수 있다. 매복치의 치료 방법으로는 우선적으로 외과적노출술을 생각해 볼 수 있으며, 외과적노출술 후에추가적인 인위적 아탈구로 자발적맹출을 기대해 볼 수도 있다. 자발적맹출이 관찰되지 않으면 교정적 강제 견인이나 외과적재위치술을 고려해 볼 수 있으며, 최악의 경우에는 발치 후 보철치료를 준비해야 할 것이다. 맹출장애를 보이는 치아의 조기진단과 치료는 중요한 의미를 갖는데, 늦은 시기에 발견될 경우 자발적 맹출력이 감소되어 치료의 성공률도 감소하고, 치료기간도 증가하며 임상적으로 다양한 합병증을 야기하기 때문이다. 따라서, 하악 제1대구치의 맹출장애를 조기에 발견할 경우우선적으로 맹출유도를 고려해 볼 필요가 있다. 다음 두 증례는 매복된 하악 제1대구치에 대하여 외과적 노출술을 시행 후 자발적 맹출을 기대하였으나 상반된 결과를 얻었기에 보고하는 바이다.
Abstract
Incidence of tooth impaction varies from 5.6 to 18.8% of the population. Failure of eruption of the first and second permanent molars is rare; the prevalence in the normal population is 0.01% in case of the first permanent molar, and 0.06% in case of the second permanent molar. Permanent molars are particularly important for providing sufficient occlusal support and co-ordinating facial growth. Failure of eruption of permanent molars may result in various complications such as decrease in vertical dimension, posterior open bite, extrusion of antagonistic teeth, resorption and inclination of adjacent teeth, formation of cyst and so on. Treatment options of impacted teeth are periodic observation, surgical exposure, surgical exposure with subluxation, orthodontic relocation,and surgical extraction before prosthetic treatment. Early diagnosis and treatment are important, because delayed treatment induces various problems such as decreased spontaneous eruptive force, decreased successful percentage, increased treatment period, increased various complications. Prevalence of the failure of mandibular first molars is rare but eruptive guidance before extraction of impacted teeth is necessary due to importance of permanent molars. We reported two cases of surgical exposure of impacted mandibular first molar. In these cases, we could observe different result of the impacted mandibular first molar after surgical exposure.
