Abstract

The purpose of this study was to provide the reference data evaluating the treatment effect of orthopedic appliances. The skeletal and dental growth increments were measured in 24 normal mixed dentition children (boys: 14, girls: 10) by three serial lateral cephalograms: initial mean age: 9${\pm}$1.3 years, mean observation period: 13${\pm}$1.3 months. Cephalometric changes were analysed. The results were as follows: 1. In boys, the maxilla showed forward and downward growth pattern and the mandible showed forward growth pattern (p<0.05). In girls, the maxilla and mandible showed forward and downward growth pattern(p<0.05). 2. Horizontal growth of both maxilla and mandible in girls was superior to those in boys (A point; girls: 2.39mm, boys: 1.26mm, with p<0.05), whereas vertical growth of both maxilla and mandible in boys was similar to those in girls. 3. The change in tooth axis showed labioversion of upper incisor (p<0.01) and comparatively stable lower incisor position.

혼합치열기 정상교합 아동 24명(남:14명, 여:10명, 초진 시 평균 나이 9${\pm}$1.3세, 평균 관찰 기간: 13${\pm}$1.3개월)에 대한 성장량을 측정하여 기능적 교정장치의 순수 치료효과를 평가하는데 도움이 되기 위해 3회(5${\sim}$8개월 간격) 촬영한 측모 두부방사선 규격 사진에 대한 분석 결과 다음과 같은 결론을 얻었다. 1. 남아는 상악골은 전하방, 하악골은 전방성장하였고, 여아는 상하악골이 전하방 성장하였다(p<0.05). 2. 상하악골의 남녀간 차이에서 수평적 성장상태는 여아가 컸고(A point 여아: 2.39mm, 남아: 1.26mm, p<0.05), 수직적 성장상태는 유의한 차이가 없었다. 3. 상악 전치의 치축은 두개저에 대해서 순측 경사하였고(p<0.01) 하악 전치의 치축은 큰 변화가 없었다.
