目的:探讨骨性Ⅰ、Ⅱ、Ⅲ类错患者自然头位、颅面形态与颈椎姿势的关系。方法:测量86例8~15岁均角错患者自然头位头颅侧位片并对测量项目进行统计分析。结果:颅部水平参考线与真垂线之间的夹角及颅颈角在骨性Ⅱ类错最大,骨性Ⅲ类错最小。结论:骨性Ⅰ、Ⅱ、Ⅲ类错畸形间自然头位及颈椎姿势有显著差别。
Objective: To investigate the relationship between natural head position, craniofacial morphology and cervical posture in patients with skeletal Class Ⅰ, Ⅱ, Ⅲ malocclusion. Methods: 86 cases of 8 ~ 15-year-old patients with angle-head fractures of the natural head cephalograms were made and the measurement items were statistically analyzed. Results: The angle between skull horizontal reference line and true perpendicular and craniocervical angle were the highest in skeletal Class Ⅱ malocclusion and the lowest in skeletal Class Ⅲ malocclusion. Conclusion: There are significant differences between natural head position and cervical posture of skeletal Class Ⅰ, Ⅱ and Ⅲ malocclusion.
