Objective To investigate the growth and development pattern of mandible with cervical vertebral maturation stage(CVMS)in Northeast China,associated with analyzing the coordination of mandible development in three-dimensions,and explore the gender differences on the mandible development.Methods A total of 420 patients who came from Northeast China were chosen randomly from the visitors to the Department of Orthodontics Hospital of Stomatology Jilin University from 2017 to 2022.The enrolled participants were grouped by gender and CVMS.A total of 11 landmarks and 14 items were pointed and measured via Dolphin software(version 11.9).One-way ANOVA and T-test were employed for statistical analysis using SPSS(version 26.0).Results ①There was a significant correlation between most of the measurement items and CVMS;② Most of the growth measurements were concentrated in the CVMS Ⅱ to CVMS Ⅳ stage,and the growth peak of female usually ends earlier than that of male;③The mandible development showed an unbalanced growth pattern.In the early stage,the growth rate was about vertical＞horizontal=sagittal in male,while the growth rate was vertical=sagittal＞horizontal in female;④At the same CVMS,there were significant gender differences in the increase rate of mandible growth(P＜0.05).Conclusion The growth and development of mandible in Northeast Chinese population showed developmental characteristics related to CVMS,and similar but different developmental patterns were observed between males and females.
