摘要

前言和目的了解牙弓发育模式对青少年错牙合的准确诊断和治疗至关重要。然而，基于大数据的大规模、特定区域的分析却很少。本研究旨在了解中国青少年牙弓生长模式，以完善早期正畸治疗策略。方法对2020年7月至2021年6月收集的5951名中国青少年的3D数字印象进行回顾性横断面分析。人工智能辅助测量描绘了牙弓尺寸，使用局部加权回归来绘制发展趋势，并使用Lasso回归来探索影响因素，特别关注地理差异。结果不同性别、不同纬度人群的牙弓尺寸存在显著差异。男性通常比同龄女性显示出更大的弓尺寸。男性年龄为13.7岁，女性年龄为13.1岁，牙弓生长迅速，后期生长潜力有限，牙弓尺寸大小存在明显的地区差异。这些变化与地理纬度显著相关，强调了环境因素对牙弓发育的影响。结论：在先进的人工智能方法的帮助下，本研究为中国青少年牙弓发育提供了有价值的区域见解。牙弓的拟合曲线为优化早期正畸治疗策略提供了有价值的见解。研究结果提倡因地制宜的正畸规划，并强调人工智能在提高正畸治疗精度方面的潜力。我们对5951个3D牙齿模型的研究揭示了牙弓生长的性别和地域差异，突出了青少年前的快速生长和后期的局限性，为治疗计划提供了信息。

Dental Arch Development of Chinese Adolescents: A Retrospective Cross-Sectional Study

Introduction and aims

Understanding the patterns of dental arch development is crucial for precise diagnosis and management of malocclusion in adolescents. However, large-scale, region-specific analyses based on big data are scarce.This study aimed to identify the dental arch growth patterns of Chinese adolescents to refine early orthodontic treatment strategies.

Methods

A retrospective cross-sectional analysis was conducted using 3D digital impressions from 5951 Chinese adolescents, collected between July 2020 and June 2021. AI-assisted measurements delineated dental arch dimensions, which were analyzed using locally weighted regression to chart developmental trends and Lasso regression to explore influencing factors, with a particular focus on geographical variances.

Results

Significant differences in dental arch dimensions were observed between genders and across different latitudes. Males generally displayed larger arch dimensions than females of the same age. The dental arches experienced rapid growth before age 13.7 in males and 13.1 in females, with limited growth potential in later years, with regional disparities evident in the magnitude of dental arch dimensions. These variations were prominently associated with geographical latitude, underscoring the influence of environmental factors on dental arch development.

Conclusion

This comprehensive study provides valuable regional insights into the dental arch development of Chinese adolescents, facilitated by advanced AI methodologies. The fitted curves of age-specific dental arch offer valuable insights for optimizing early orthodontic treatment strategies. The findings advocate for region-tailored orthodontic planning and highlight the potential of AI in enhancing the precision of orthodontic treatment.

Clinical Relevance

Our study of 5951 3D dental models reveals gender and geographical differences in arch growth, highlighting pre-teen rapid growth and later limitations, informing treatment planning.
