目的比较不同骨型的错牙合患者头位、颈椎位置的差异,寻找颅面发育和自然头位、颈椎位置之间的关系。方法选择79名错牙合患者,年龄12～16岁,按ANB和NSL-MP分组,比较各组自然头位和颈椎位置的差异,并与颅面形态指标进行相关分析。结果按ANB分组,无指标显示显著差异;按NSL-MP分组,多个指标显示显著差异。结论患者的头位、颈椎位置与颅面的垂直向、矢状发育有关,而与上下颌骨间的矢状关系无关。
Objective To compare the differences of head position and cervical position among patients with different types of malocclusion and to find the relationship between craniofacial development and natural head position and cervical position. Methods Totally 79 patients with malocclusion were selected, aged from 12 to 16 years old. All patients were divided into two groups according to ANB and NSL-MP. The differences of natural head position and cervical position were compared between the two groups. Results ANB grouping, no indicators showed significant differences; by NSL-MP group, multiple indicators showed significant differences. Conclusion The head position and cervical position of the patient are related to the vertical and sagittal development of the craniofacial surface, but not to the sagittal relationship between the upper and lower jaws.
