骨性Ⅰ、Ⅱ、Ⅲ类错患者自然头位、颅面形态与颈椎姿势的研究

Natural Head Position,Craniofacial Morphology and Cervical Posture in Skeletal ClassⅠ,Ⅱ,Ⅲ Malocclusion

目的：探讨骨性Ⅰ、Ⅱ、Ⅲ类错殆患者自然头位、颅面形态与颈椎姿势的关系。方法：测量86例8～15岁均角错胎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类错骀最大，骨性Ⅲ类错殆最小。结论：骨性Ⅰ、Ⅱ、Ⅲ类错殆畸形间自然头位及颈椎姿势有显著差别。

Objective： To investigate the relationship among natural head position, craniofacial morphology and cervical posture of skeletal Class I , Ⅱ , Ⅲ malocclusion. Methods： We measured and analysis cephalometric radio graphs in natural head position of 86 patients with average angle aged 8 to 15. Results： The angle between horizontal reference line in cranium and the ture vertical line as well as cranial-cervical angle were the largest in Class Ⅱ mal occlusion, and the smallest in Class HI malocclusion. Conclusion： Significant differences exist in natural head posi tion and cervical posture among skeletal Class Ⅰ , Ⅱ, Ⅲ malocclusion.
