Abstract

The purpose of this study was to assess the growth changes of craniofacial complex and to establish Korean norms by McNamara's cephalometric analysis. Lateral cephalograms were obtained from males and females with normal occlusion & acceptable profiles in 9-21 years of age. The lateral cephalograms of males & females in 9-13 years of age were serial cephalometric radiograms which were taken at 2 year interval. 11 landmarks, 10 planes and 3 angles were plotted and measured linearly and angularly. The results were as follows: 1. The author made the tables of means, standard deviations in each item, sex, age. 2. During 9-13 years of age, annual growth increments of effective maxillary length, effective mandibular length and lower anterior facial height were 1.90, 2.89 and 0.99mm. 3. The prediction tabulation was made in an attempt to predict effective mandibular length & lower anterior facial height derived from effective maxillary length.

McNamara씨 분석법에 의한 악안면골의 성장변화 평가 및 한국인 기준치를 얻고자 정상적인 안모 및 교합을 가졌다고 생각되는 $9\~21$세의 388명(9세, 11세, 13세는 2년 간격으로 누년적으로 얻은 것임)을 대상으로 두부방사선규격 사진을 분석하여 다음과 같은 결론을 얻었다. 남녀별 각 계측항목의 연령에 따른 평균치 및 표준편차를 산출하였다. $9\~13$세 사이에서 effective maxillary length, effective mandibular length, lower anterior facial height는 연평균 각각 1.90, 2.89, 0.99mm 증가하였다. 주어진 effective maxillary length에 대한 적절한 effective mandibular length, lower anterior facial height를 추정 할 수 있는 회귀방정식을 얻었다.
