The associations between dentoalveolar morphology and the posture of the head and the cervical column were studied in a sample of 120 Danish male students aged 22-30 years. Two head positions were recorded on lateral cephalometric radiographs, one determined by the subjects's own feeling of a natural head balance (self balance position) and the other by the subject looking straight into a mirror (mirror position). Dentoalveolar morphology was described by 17 linear and angular variables and postural relationships by 18 angular variables. The position of the head in relation to the cervical column showed positive correlations with the anterior upper and lower dentoalveolar heights and with the inclinations of the upper and lower occlusal planes. These correlations were considered to reflect the dentoalveolar compensatory adaptation to the variation in vertical jaw relationship, which in a previous study had been found to be associated with craniocervical angulation. No associations were observed between craniocervical angulation and alveolar prognathism or incisor inclination. This was in accordance with the previous findings of a lack of associations between sagittal jaw relationship and craniocervical angulation.
在120名年龄在22至30岁的丹麦男学生样本中，研究了牙槽形态与头部和颈椎姿势之间的关联。在头颅侧位片上记录了两个头部位置，一个由受试者自身感觉自然头部平衡来确定（自我平衡位置），另一个由受试者直视镜子来确定（镜子位置）。牙槽形态由17个线性和角度变量描述，姿势关系由18个角度变量描述。头部相对于颈椎的位置与上前牙和下前牙牙槽高度以及上下咬合平面的倾斜度呈正相关。这些相关性被认为反映了牙槽对垂直颌关系变化的代偿性适应，在先前的一项研究中发现这种垂直颌关系变化与颅颈角度有关。未观察到颅颈角度与牙槽前突或切牙倾斜度之间存在关联。这与先前关于矢状颌关系与颅颈角度之间缺乏关联的研究结果一致。
