A comprehensive cephalometric comparison between unselected Chinese and Caucasian 12-year-old male children in natural head posture finds the intracranial reference planes to slope down more caudally in the Chinese. By superimposing on true vertical, the degree of prognathism in the Chinese becomes apparent. Significant intergroup differences are highlighted for both selected dentoskeletal and soft tissue profile variables.
一项针对未经过筛选的自然头位状态下的中国和高加索12岁男性儿童的全面头影测量比较发现,中国儿童的颅内参考平面更向尾侧倾斜。通过与真正的垂直方向叠加,中国人的前突程度变得明显。对于选定的牙颌面和软组织侧貌变量,两组之间存在显著差异。
