Abstract:
Objective:To clarify the morphological relationship between the upper airway and TMJ in patients with normal-angle skeletal Ⅱ and skeletal Ⅰ malocclusion.Methods:30 skeletal class Ⅰ and 22 skeletal class Ⅱ patients with normal-angle were included.CBCT examination was performed,and Mimics 21.0 software was used to conduct 3D reconstruction and measurements of the samples.Data was analyzed by using independent t-test and the Pearson correlation test.Results:12 measurements,including the sagittal diameter of nasopharyngeal segment,the sagittal,coronal diameter,minimum cross-sectional area,the volume of palato-pharyngeal segment and glossopharyngeum segment,the total volume of upper airway,posterior oblique slope of the articular eminence and the length of the condylar showed significant differences between skeletal Ⅱ and skeletal Ⅰ subjects with normal-angle(P＜0.05).The posterior oblique slope of the articular eminence showed a positive correlation with the sagittal diameter of the palatopharyngeal segment,volume and minimum cross-sectional area of glossopharyngeum lingual segment(P＜0.05).The liner ratio showed a negative correction with the coronal diameter of palatopharyngeal and glossapharyngeal segment as well as minimum cross-section area of glos-sapharyngeal segment(P＜0.05).Conclusion:The structure of upper airway is correlated with that of TMJ.Differences in the upper airway are statistically significant between skeletal Ⅱ and skeletal Ⅰ malocclusion with normal-angle(P＜0.05).
