摘　　要：目的:探究锥形束CT(CBCT)测量对骨性Ⅲ类错牙合患者正畸治疗后牙槽骨形态变化的应用价值。方法:选取2020年1月至2023年12月期间在无锡口腔医院接受正畸治疗的50例骨性Ⅲ类错牙合患者,并将其纳入治疗组,选取同期未接受正畸治疗的50例骨性Ⅲ类错牙合患者纳入对照组,比较两组牙槽骨高度、牙槽骨宽度及牙槽骨密度,以及牙根周围骨密度、牙齿倾斜度及牙齿移动距离。结果:治疗组患者牙槽骨的远中高度(5.89±0.25)mm、近中高度(5.48±0.11)mm、颊侧高度(6.37±0.31)mm及舌侧高度(6.12±0.28)mm均高于对照组的(5.23±0.12)、(5.11±0.08)、(6.01±0.17)和(5.79±0.15)mm,两组比较差异有统计学意义(t=16.829、19.235、7.200、7.346,P<0.05);治疗组患者牙根位置和鼻底位置的牙槽骨宽度均高于对照组,两组比较差异有统计学意义(t=23.566、26.785,P<0.05);治疗组患者牙槽骨密度和牙根周围骨密度均高于对照组,两组比较差异有统计学意义(t=6.470、6.042,P<0.05),上颌切牙倾斜度和下颌切牙倾斜度均高于对照组,两组比较差异有统计学意义(t=3.710、160.815,P<0.05);治疗组患者牙齿的水平移动、垂直移动、内外移动及旋转距离均大于对照组,两组比较差异有统计学意义(t=62.757、115.000、75.000、5.728,P<0.05)。结论:在正畸治疗的过程中,CBCT测量具有重要意义及作用,能够实现对牙槽骨形态变化的细致观察和精确量化分析。Objective:To explore the application value of cone-beam computed tomography(CBCT)measurement in morphological change of alveolar bone of patients with malocclusion of osseous class III after orthodontic treatment.Methods:A total of 50 patients with malocclusion of osseous class III after received orthodontic treatment in Wuxi Stomatology Hospital from January 2020 to December 20203 were selected,and they were included in the treatment group,and 50 patients with same condition who did not receive orthodontic treatment in the same period were included in the control group.The height,width and density of alveolar bone of two groups,as well as the bone density surrounding the tooth root,the tooth inclination,the movement distance of tooth,and the CBCT images between before and after treatment,were compared.Results:The heights of long to medium(5.89±0.25)mm,near to medium(5.48±0.11)mm,cheek side(6.37±0.31)mm and tongue side(6.12±0.28)mm of treatment group were all higher than those[(5.23±0.12)mm,(5.11±0.08)mm,(6.01±0.17)mm and(5.79±0.15)mm]of control group,and the differences of them between two groups were significant(t=16.829,19.235,7.200,7.346,P<0.05),respectively.The widths of alveolar bones of tooth root and nasal base of treatment group were all higher than those of control group,and the differences of them between two groups were significant(t=23.566,26.785,P<0.05),respectively.The alveolar bone density and the density surrounding tooth root of treatment group were all higher than those of control group,and the differences of them between two groups were significant(t=6.470,6.042,P<0.05),respectively.The inclinations of upper and lower incisors of treatment group were all higher than those of control group,and the differences of them between two groups were significant(t=3.710,160.815,P<0.05),respectively.The horizontal movement,vertical movement,internal and external movement,and rotational distance of the teeth of treatment group were all larger than those of control group,and the differences of them
