From the serial sample of the Burlington Growth Centre, 68 children with Angle Class II malocclusion were contrasted with 148 children with Class I occlusion. Body height, cranial height, cranial base flexure and jaw position relative to the cranium were compared at ages 8, 12 and 16 years. In the Class II groups, the cranial base angle was significantly (P less than .05) larger, upper cranial height was slightly larger, lower cranial height was slightly smaller, the maxilla was slightly more posterior to Sella, and the mandible was significantly more posterior. Between ages 8 and 16 years, lower cranial height increased and cranial base angle decreased, with a strong negative correlation. Lower cranial height and the anterior position of the maxilla and mandible from Sella correlated significantly (P less than .01) with body height in Class I children, but in Class II only in boys 8 and 12 years of age. This lower correlation in Class II children was accounted for by those with a moderate to tall stature but disproportionately small lower cranial height. In Class II children the jaws, especially the mandible, had a more posterior position under the cranium, and there was a more open flexure of the cranial base and shorter lower cranial height. Correlation of stature with lower cranial height and with the anterior position of the jaws relative to the cranium was much lower in Class II children, especially in girls.
从伯灵顿生长中心的系列样本中，将68例安氏II类错牙合儿童与148例I类牙合儿童进行对比。比较了8岁、12岁和16岁时的身高、颅高、颅底曲度以及颌骨相对于颅骨的位置。在II类组中，颅底角显著更大（P小于0.05），上颌颅高略大，下颌颅高略小，上颌相对于蝶鞍更靠后，下颌明显更靠后。在8岁至16岁之间，下颌颅高增加，颅底角减小，呈强负相关。在I类儿童中，下颌颅高以及上颌和下颌相对于蝶鞍的前部位置与身高显著相关（P小于0.01），但在II类中仅在8岁和12岁的男孩中如此。II类儿童中这种较低的相关性是由那些身材中等至较高但下颌颅高不成比例较小的儿童造成的。在II类儿童中，颌骨，尤其是下颌骨，在颅骨下方的位置更靠后，颅底曲度更开放，下颌颅高更短。在II类儿童中，尤其是女孩，身高与下颌颅高以及颌骨相对于颅骨的前部位置的相关性要低得多。
