目的:研究不同垂直骨面型错合畸形患者颈椎姿势的特点及差异,为正畸矫治错合畸形获得较好的临床效果及颅面、颈部生长发育的研究提供一定的参考依据。方法:采用计算机辅助X线头影测量技术,对226例不同垂直骨面型的儿童、成人在自然头位时拍摄的头颅定位侧位片进行测量研究,分别比较儿童以及成人不同垂直骨面型间颈椎姿势的差异。结果:儿童:CVT-OPT、SN-CP、SN-OPT及SN-CVT在低、均、高角各组间的差别均无统计学意义。成人:CVT-OPT在低角组与高角组间、均角组与高角组间的差别有统计学意义,高角组低于低角组和均角组,在低角组与均角组间的差别无统计学意义;SN-CP在低、均、高角各组间的差别有统计学意义,低角组<均角组<高角组;SN-OPT及SN-CVT在低角组与高角组间的差别有统计学意义,低角组<高角组,在低角组与均角组间、均角组与高角组间的差别无统计学意义。结论:不同垂直骨面型错合畸形患者的颈椎姿势在儿童无显著差异,在成人差异显著。 OBJECTIVE: To study the characteristics and differences of cervical posture of patients with different types of orthognathic bone malocclusion, and to provide some references for orthodontic treatment of malocclusion with better clinical results and craniofacial and cervical growth and development. Methods: Using computer-aided X-ray cephalometric technique, 226 cases of vertical vertebrae of children and adults with head position were photographed to measure the lateral position of the skull. The differences between children and adults with different vertical bone surface types Differences in cervical posture. Results: There was no significant difference in children between CVT-OPT, SN-CP, SN-OPT and SN-CVT in low, average and high-angle groups. Adults: CVT-OPT in low-angle group and high-angle group, the average angle between the group and the high-angle group differences were statistically significant, high angle group was lower than the low angle group and the average angle group, in the low angle group and the average angle group The differences of SN-CP between the low-angle group and the high-angle group were statistically significant. In the low-angle group
