摘　　要：目的:探讨骨性Ⅱ类不同垂直骨面型成年女性患者髁突骨密度、体积和表面积的特征。方法:回顾性病例对照研究,以18~30岁女性患者为研究对象,测量其头颅侧位片,筛选出骨性Ⅱ类高角、均角、低角各50例,获取其CBCT影像,用Mimics Reseach 20.0软件对髁突进行三维重建,测量髁突骨密度,体积及表面积,运用单因素方差分析(ANOVA)比较3组髁突测量指标的差异。结果:3组间髁突骨密度、体积及表面积的差异具有统计学意义(P<0.05)。两两比较显示,髁突骨密度高角组<均角组(P<0.05),均角组<低角组(P<0.05),高角组<低角组(P<0.001);髁突体积、表面积高角组<低角组(P<0.05),均角组<低角组(P<0.05),高角组<均角组(P>0.05)。结论:骨性Ⅱ类不同垂直骨面型成年女性患者髁突骨密度、体积和表面积具有差异。Objective:To investigate the difference of condylar bone density,volume and surface area in adult female patients with different vertical skeletal features of skeletal ClassⅡ.Methods:This study was a retrospective case-control study.150 female patients aged 18-30 years were included as the subjects.Lateral cephalic radiographs were measured and the cases with high angle,average angle and low angle of skeletal ClassⅡwere included and respectively grouped(n=50),the CBCT images were collected,the condyles were reconstructed by Mimics Reseach 20.0 software,the bone density,volume and surface area of the condyles were measured.Univariate analysis of variance(ANOVA)was used to compare the difference of condyle measurements among the 3 groups.Results:The overall difference of condylar bone density,volume and surface area among the 3 groups were statistically significant(P<0.05).Pairwise comparison showed that the condyle bone mineral density in high angle group was lower than that in average angle group(P<0.05),in average angle group was lower than that in low angle group(P<0.05),in high angle group was lower than that in low angle group(P<0.001).Condyle volume and surface area in high angle group were lower than those in low angle group(P<0.05),in average angle group was lower than those in low angle group(P<0.001),in high angle group was lower than those in average angle group(P>0.05).Conclusion:The condyle bone density,volume and surface area of the different vertical skeletal features of skeletal classⅡin adult female patients are different.
