摘　　要：目的:研究青少年Ⅱ类错[牙合]患者经过隐形矫治器下颌前导治疗前、后上气道形态结构的三维变化。方法:选取于2018~2021年于我科采用隐形矫治器治疗安氏Ⅱ类错[牙合]患者17例,通过CBCT测量治疗前后上气道变化。结果:治疗后上气道总体积以及鼻咽段、腭咽段、舌咽段气道体积显著增加,上气道最小横截面积以及上气道后鼻棘平面、软腭平面、会厌尖平面处横截面积增加。结论:隐形矫治器下颌前导治疗能够使青少年Ⅱ类错[牙合]患者上气道容积增大,改善患者的上气道形态,进而可能增加上气道通气量、改善青少年呼吸功能。Objective:To study the three-dimensional changes of upper airway morphology and structure in adolescent patients with Class Ⅱ malocclusion before and after mandibular anterior guidance treatment with clear aligner.Methods:Seventeen patients with Angle’s Class Ⅱ malocclusion in our hospital from 2018 to 2021 were treated with clear aligner,and the changes of airway before and after treatment were measured by CBCT.Results:After treatment,the total volume of the upper airway and the airway volumes of the nasopharynx,palatopharynx and glossopharynx segments of the upper airway increased significantly,and the minimum cross-sectional area of the upper airway and the cross-sectional area at the nasal spine plane,soft palate plane and epiglottis apical plane after the upper airway increased.Conclusion:Mandibular advancement therapy with clear aligner can increase the upper airway volume of adolescent patients with Class Ⅱ malocclusion and improve the shape of the upper airway.It may further increase the upper airway ventilation and improve the respiratory function of adolescents.
