Abstract
Postpubertal craniofacial growth changes were assessed from serial lateral cephalograms taken at which subjects were 16 and 18 years of age. The sample consisted of 19 male and 14 female subjects with no previous orthodontic treatment who had normal occlusion. The craniofacial growth changes of these samples during this study period might be summarized as follows 1. Significant increase in mean maxillary and mandibular length, cranial base length, posterior md anterior facial height were observed at the age period studied in male(P<0.05), however, in female significant increase was observed only mandibular length(Ar-Gn, Ar-Go) and anterior and posterior facial height(P<0.05). 2. Total growth increment of all measumenats were below 1mm in female, but in male, total mandibular(Ar-Gn) growth increment was 2.0mm and those of mandibular tody length, ram length, posterior facial height, and anteior facial height were 1 to 1.54mm and the others were below 1mm 3. A closing, forward rotation of the mandible occured with a significant decrease in mandibular plane angle of
정상교합자의 사춘기 이후의 두개안면골 성장변화를 평가하기 위하여, 16세와 18세에 촬영한 연속 두부X선규격사진을 분석하였다. 대상은 남자 19명과 여자 14명이였으며 이들의 평균연령은 16.5세와 18.5세이였다. 관찰기간동안에 남자는 상,하악골, 두개저, 전,후방안면높이에서 통계적으로 유의한 증가가 있었으나(P<0.05), 여자에서는 하악골길이(Ar-Gn, Ar-Go) 그리고 전,후방안면높이에서만 유의한 증가가 있었다(P<0.05). 그러나 이 기간 동안 성장량은 여자에서는 전 계측항목에서 1mm이하 였으며, 남자에서는 전체 하악골길이 (Ar-Gn)는 2mm, 하악체길이 (Go-Me), 하악지길이(Ar-Go), 전,후방안면높이 (Na-Me, S-Go)는
