초록

이 후향적 연구의 목적은 한국 성장기 아동의 수직적인 안모 형태와 성별에 따라 골격적 성숙도와 치아의 성숙도를 평가하는 것이다. 총 184명의 8 - 14세 소아∙청소년을 대상으로 진행하였다. 하악평면각을 기준으로 3개의 군으로 나누었으며 성별 간 비교를 위해 3개의 군을 각각 남아와 여아의 하위 군으로 나누었다. 골격적 성숙도와 치아 성숙도는 측모두부 방사선 사진, 수완부 방사선 사진, 파노라마 방사선 사진으로 평가하였다. 수직적 성장군은 수평적 성장군보다 경추골 및 수완부 골의 높은 성숙도를 보였다. 치아 성숙도는 수직적 성장군에서 가장 높았다. 남아보다 여아에서 골격적 성숙도가 더 높았으며 치아 성숙도는 성별 간 유의한 차이는 관찰되지 않았다. 환자의 수직적 안모 형태 분석은 교정치료 시작 시기 결정에 도움이 되는 보조지표를 제공할 수 있으며, 수직적 안모 형태를 보이는 환자의 경우 교정치료를 조기에 시작하는 것을 고려할 수 있다.

The purpose of this retrospective study was to evaluate the skeletal and dental maturity according to the vertical facial type and sex in Korean children in the developmental stage. In total, 184 participants aged 8 - 14 years were selected and divided into three groups based on the mandibular plane angle. For the comparison between the sexes, the three groups were each divided into male and female subgroups. The skeletal and dental maturity were assessed using lateral cephalograms, hand-wrist radiographs and panoramic radiographs. The vertical growth group showed significantly greater cervical vertebral and hand-wrist maturity than that in the horizontal growth group. Dental maturity was the highest in the vertical growth group. Girls showed greater skeletal maturity than boys, and no distinct difference was observed between the dental maturity of the sexes. Analysis of the vertical facial type in children can provide ancillary indicators that may help determine the optimal timing for orthodontic treatment initiation. Earlier initiation of orthodontic treatment may be considered for patients with vertical facial growth patterns.
