맹출연령에 도달했음에도 맹출이 지연되고 임상검사와 방사선사진 검사를 통해 불완전한 맹출이 예상되는 치아로 정의되는 매복치는 흔한 교정적 문제 중 하나이다. 매복치는 유치 치근의 흡수지연, 외상, 맹출 순서의 이상, 공간부족, 비타민 D의 결핍 등의 다양한 원인으로 발생하며 심미적 기능적 문제 뿐 만아니라 인접치의 치근 흡수, 낭종, 부정교합 등의 문제를 유발할 수 있으므로 적절한 치료가 요구된다. Hou 등은 매복치의 발생빈도를 6.15%라 하였으며, Grover 와 Lorton은 96.5%(제3대구치 포함), Nagahara 등은 4.9%로 보고하는 등 많은 선학들에 의하여 매복치의 발생빈도에 관한 연구는 다양하게 진행되어 왔다. 또한 매복치의 성공적인 교정치료를 위하여 고려하여야 하는 사항인 수평매복 또는 수직매복 등의 매복양상, 협측 또는 설측매복 등의 매복 위치, 견인고리의 부착을 위하여 적용한 수술기법, 치료의 성공률 등 에 대한 연구 결과가 보고되고 있으나 한국인을 대상으로 한 이러한 매복치의 임상적 및 방사선학적 특성에 대한 연구는 충분하지 않다. 본 연구는 가천의대 길병원 치과교정과에 매복치를 주소로 내원한 교정환자들을 통하여 한국인 매복치 환자의 특성과 치료기간 및 방법을 알아보기 위하여 시행되었다.
Abstract
Purpose : An impacted tooth is defined as a tooth that shows delayed eruption and is expected to erupt incompletely by clinical and radiograph examination despite it reaching its expected time of eruption. The aims of this study were to investigate the clinical and radiological characteristics and treatment duration and method of impacted teeth in Korean patients. Materials and Methods : For this study we used clinical records, study models, panoramic radiographs and intraoral photographs of patients who attended Gachon University Gil Hospital Orthodondtic Department between 2005 and 2008. There were 164 patients with a total number of 202 impacted teeth. Results : Male patients shows a little more prevalence than female patients (1.13:1). The under 12 age group had the highest prevalence of tooth impaction, and the over 19 age group showed the least prevalence of tooth impaction. The ratio of tooth impaction between the left to right ratio was 1.73:1 and maxilla and mandible was 1.84:1. The impacted teeth were most commonly positioned buccally (76 cases, 41.5%). Full flap closure technique (108 cases, 81.2%)was most frequently used for attachment of surgical traction hooks. Maxillary canine impaction was most commonly encountered both in male and female patients. The mean treatment period was 12.2 months and the success rate of treatment was 90.3%. The canine tooth shows the longest treatment time and highest failure rate. The ankylosis was the major cause of failure. Conclusion: Impacted teeth most commonly show in left side maxilla in the under 12 age group. And it is most commonly positioned buccally. The mean treatment period was 12.2 months, and the success rate of treatment was 90.3%.
