目的:研究不同程度深覆患者颈椎异常的发病率及其与颅面形态间的关系。方法:根据深覆程度将124例深覆患者分成3组作为实验组,48例正常覆患者作为对照组,检查颈椎融合、后弓发育缺陷的发病率,对头颅侧位片各测量指标与颈椎异常的关系进行相关性分析。结果:4组患者颈椎正常、颈椎融合、2个以上异常的发生率有统计学差异;4组测量值中PP-MP、SN-MP、SNB、ANB、A-N-Pog、ILs-PP、覆、覆盖值有统计学差异;其中PP-MP、ANB、A-N-Pog、ILs-PP、覆、覆盖与颈椎异常存在相关性。结论:深覆越重的患者其颈椎融合的发生率越高且2个以上变异的发生率也越高;下颌位置、上下颌间高度、覆牙合和覆盖与颈椎异常相关。
Objective: To study the incidence of cervical abnormalities and its relationship with craniofacial morphology in patients with deep overburden. Methods: One hundred and twenty-four patients with deep overburden were divided into three groups according to the degree of deep overburden, and 48 patients with normal overburden as the control group. The incidences of cervical fusion and posterior bowel developmental defects were examined. The correlation between index and cervical abnormalities was analyzed. Results: There was a significant difference in the incidence of cervical spondylosis, cervical fusion and more than 2 abnormalities among the 4 groups. The changes of PP-MP, SN-MP, SNB, ANB, AN-Pog, ILs-PP, There was a significant difference in coverage between the two groups. There was a correlation between PP-MP, ANB, AN-Pog, ILs-PP, CONCLUSIONS: The incidence of cervical fusion is higher in patients with overgrowth and the incidence of more than two variations is higher. The position of mandible, the height of maxilla and mandible, overbite and coverage are related to abnormal cervical spine.
