目的建立广东地区青少年和成年女性面部软组织三维形态学模型，比较广东地区偏高偏高骨性II类女性与偏高骨性I类女性面部软组织的形态学特征。3dMDface系统用于捕获160名患者的面部扫描，包括45名正常和35名过度发散骨骼II类青少年（年龄11-14岁）和45名正常和35名过度发散骨骼II类成人（年龄18-30岁）。利用3dMDvultus分析软件对32个软组织标志点进行标测，获得21个线性、10个角度和17个比率测量值。两个独立的样本之间的正常青少年和成人组和正常和hyperdivergent骨骼II类组的t检验数据进行了评估。广东成年女性的线性测量值在I类和II类组均大于青少年。然而，角度和比率测量没有显著差异。高发散II类组的垂直线测量值较高，矢状线和横向线测量值较小（p < 0.05）。在过度发散II类组中，软组织ANB角、颏唇角和下颌角显著较大，软组织面部凸面角和鼻凸面角显著较小（p < 0.05）。此外，高发散II类组与对照组之间的比率测量值存在显著差异（p < 0.05）。获得了广东省青少年和成年女性的面部三维形态。成年人面部软组织的测量值在三个维度上均较高，但面部凸度和比例关系相似，表明生长模式保持不变。三维面部软组织的特点是高发散骨骼II类的术语“长，凸，窄”。三维面部测量可以反映内在的硬组织特征。在线版本包含补充材料，可通过10.1186/s12880-022-00782-w获得。
To establish the three-dimensional facial soft tissue morphology of adolescent and adult females in the Guangdong population and to study the morphological characteristics of hyperdivergent skeletal class II females in Guangdong compared with that of normodivergent class I groups. The 3dMDface system was used to capture face scans of 160 patients, including 45 normal and 35 hyperdivergent skeletal class II adolescents (aged 11–14 years old) and 45 normal and 35 hyperdivergent skeletal class II adults (aged 18–30 years old). Thirty-two soft tissue landmarks were mapped, and 21 linear, 10 angular and 17 ratio measurements were obtained by 3dMDvultus analysis software. Data were assessed with a t-test of two independent samples between the normal adolescent and adult groups and between the normal and hyperdivergent skeletal class II groups. The linear measurements of the Guangdong adult females were larger than those of the adolescents in both Class I and Class II groups. However, the angular and ratio measurements had no significant difference. The vertical linear measurements were higher and the sagittal and transverse linear measurements were smaller in the hyperdivergent class II group (p < 0.05). The soft tissue ANB angle, chin-lip angle, and mandibular angle were significantly larger and the soft tissue facial convexity angle and nasal convexity angle were significantly smaller in the hyperdivergent class II group (p < 0.05). Additionally, there were significant differences in the ratio measurements between the hyperdivergent class II groups and the control groups (p < 0.05). The three-dimensional facial morphology of Guangdong adolescent and adult females was acquired. The facial soft tissue measurements of the adults were higher in the three dimensions except for the facial convexity and proportional relationships which were similar, suggesting that the growth pattern remained the same. The three-dimensional facial soft tissue features of hyperdivergent skeletal class II were characterized by the terms “long, convex, and narrow”. Three-dimensional facial measurements can reflect intrinsic hard tissue characteristics. The online version contains supplementary material available at 10.1186/s12880-022-00782-w.
