本研究的目的是阐明颅底角、颌面部成分的形态变化和前颅底长度生长之间的相互关系。本次调查纳入了 122 名乳牙列正常咬合的 3-5 岁日本儿童。为了分析颅底结构与颌面部成分之间的关系，根据通过 NSAr 角（颅底角）大小评估的面部类型（前颌、正颌或后颌）将受试者分为三组。这些分类的头影测量轮廓表明颌面部组件的前后位置对应于 NSAr 角度。头影测量变量的因子分析表明，颌面部成分相对于 S-N 线的变化与颅底角密切相关。这种形态变化的正常范围与因子负荷的生长变化不同。根据这些结果，通过线性回归分析计算出具有正常咬合的头影测量轮廓的理论模型。使用这些模型，获得了 3-5 岁正常咬合儿童的与任意颅底角相关的标准轮廓。
The aim of this study was to clarify the inter-relationships between cranial base angle, the morphological variations of maxillofacial components, and growth of the anterior cranial base length. One hundred and twenty-two Japanese children aged 3-5 years with normal occlusion in the primary dentition were included in this investigation. To analyse the relationship between cranial base structure and maxillofacial components, the subjects were divided into three groups according to facial type (prognathic, orthognathic, or retrognathic) assessed by the magnitude of their NSAr angle (as cranial base angle). These categorized cephalometric profiles suggested that the antero-posterior location of the maxillofacial components corresponded to the NSAr angle. Factor analysis of cephalometric variables showed that the variation of maxillofacial components from the S-N line was strongly related to the cranial base angle. This normal range of morphological variation was distinguished from that of growth by the factor loadings. From these results, theoretical models of cephalometric profiles with normal occlusion were computed by linear regression analysis. Using the models, a standard profile related to an arbitrary cranial base angle was obtained for children with normal occlusion, aged 3-5 years.
