摘要
目的研究发育高峰前后期骨性Ⅱ类错牙合患者矢状向颌骨发育与颈椎姿势之间的相关性。方法研究以发育高峰前期和发育高峰后期骨性Ⅱ类错牙合患者各30例为研究对象,拍摄自然头位下的头颅定位侧位片,对其颅面部的发育指标与颈椎姿势的相关性进行分析。结果发育高峰前期与发育高峰后期骨性Ⅱ类错牙合患者的头位变量SN-VEL、SN-CP、SN-OPT、SN-CVT,CVT-HOR与面部结构变量SNA、SNB、Yaxis等存在显著的相关性。结论颅面形态与头颈姿势在骨性Ⅱ类错牙合患者发育的过程中是相互影响的。
Objective To study the cervical vertebrae posture and the development of craniofacial of patients before and after growth spurts with Angle Class II Malocclusion. Methods 30 cephalometric radiographs of the patients with class Ⅱ malocclusion which in their growth peak period and 30 in their later peak period were selected to measure and analyzed the head position and the variance of the craniofacial structures. The sagittal growth of the with class II malocclusion which in their growth peak period and in their later peak period were predicted. Results The cervical vertebrae posture indicators of SN - VEL, SN - CP, SN - OPT, SN - CVT and the variance of the eraniofacial structures ： SNA, SNB, ANB, Y axis of the patients with class II Malocclusion before and after their growth spurts were statistically significant （P 〈 0.05 ）. Conclusion The craniofacial morphology and cervical vertebrae posture in class II malocclusion patients in the orocess of the develooment is influenced.
