摘要: 目的: 应用锥形束CT(CBCT)分析骨性Ⅱ类错畸形患者上气道与上、下颌骨形态的相关关系。方法: 选择骨性Ⅱ类及骨性Ⅰ类错畸形成年患者各33例进行CBCT扫描,保存为Dicom文件,导入Mimics 19.0软件中进行三维重建,对2组患者上气道与上、下颌骨数据进行测量。采用SPSS 19.0软件包进行统计学分析,比较成人骨性Ⅱ类错与个别正常间上气道与上、下颌骨形态、结构的差异,以及骨性Ⅱ类错畸形患者上气道与上、下颌骨测量项目的相关关系。结果: 骨性Ⅱ类错组和个别正常组上气道形态与上、下颌骨测量结果比较,15个测量项目有显著差异(P<0.05)。骨性Ⅱ类错组上气道形态与下颌骨长度存在相关性的项目有10个,骨性Ⅱ类错组上气道形态与上颌骨宽度各测量项目中有显著相关性的项目有13个,骨性Ⅱ类错组上气道形态与下颌骨宽度各测量项目中有显著相关性的项目有3个。结论: 骨性Ⅱ类错畸形患者上气道与上、下颌骨之间具有相关关系。骨性Ⅱ类成人患者的上气道与上、下牙弓宽度也有一定相关关系。

Abstract: PURPOSE: To analyze the relationship between upper airway and mandible morphology in patients with skeletal Class Ⅱ malocclusion with cone-beam CT (CBCT). METHODS: Thirty-three volunteers with individual normal occlusion and thirty-three patients with skeletal Class Ⅱ malocclusion were selected to undergo CBCT. All samples were outputted to Dicom and reconstructed using Mimics 19.0 medical software. SPSS 19.0 software package was used to analyze the differences between the two groups. Correlation between the two groups was evaluated using Pearson's coefficient analysis. RESULTS: Fifteen parameters showed significant difference between individual normal occlusion and the skeletal Class Ⅱ malocclusion(P<0.05). There were 10 significant correlational parameters between mandible length and upper airway of the skeletal Class Ⅱ malocclusion group. There were 13 significant correlational parameters between the arch width of the maxilla and upper airway of the skeletal Class Ⅱ malocclusion group. There were 3 significant correlational parameters between the arch width of the mandible and upper airway of the skeletal Class Ⅱ malocclusion group. CONCLUSIONS: The upper airway morphology of skeletal Class Ⅱ malocclusion is correlated with maxillary and mandibular parameters.
