Biomedical research plays a critical role in advancing orthodontic innovations by identifying new targets for therapeutic interventions and developing more effective, personalized orthodontic treatment. This study evaluates the major contributors and trends in animal-related orthodontic research over the past 5 years (2017-2023).
All animal-related studies published in the eight orthodontic journals listed in the 2022 Journal Citation Reports between January 2017 and June 2023 were retrieved from the Web of Science Core Collection. After examination, the following bibliometric data were extracted from each article: title, authors, affiliations, geographic origin, year of publication, journal name, and keywords. Multiple bibliometric software packages including Biblioshiny R-package software, Datawrapper, and Datasmith were used to analyze different bibliometric outcomes.
A total of 3669 articles were screened from which 266 were selected and included in the analysis. The annual growth rate of production exhibited a decline of 11.18%. Most of the included studies focused on orthodontic tooth movement (32.3%), mainly utilizing rat models (50%). Although the United States accounted for the highest number of publications (n = 236), the trend in funded research showed a decreasing trajectory over time, with notably limited funding from the National Institutes of Health.
This study reveals a declining trend in overall animal-related orthodontic research, highlighted by a significant decrease in National Institutes of Health funding over time. To address this gap, academic institutions and professional organizations should support initiatives fostering biomedical orthodontic research.
生物医学研究通过确定治疗干预的新靶点以及开发更有效、个性化的正畸治疗方法，在推动正畸创新方面发挥着关键作用。本研究评估了过去5年（2017 - 2023年）与动物相关的正畸研究的主要贡献者和趋势。
从2022年《期刊引证报告》列出的8种正畸期刊中检索2017年1月至2023年6月发表的所有与动物相关的研究。经筛选后，从每篇文章中提取以下文献计量数据：标题、作者、单位、地理来源、发表年份、期刊名称和关键词。使用多个文献计量软件包，包括Biblioshiny R包软件、Datawrapper和Datasmith，来分析不同的文献计量结果。
共筛选出3669篇文章，其中266篇被选中并纳入分析。文章产量的年增长率下降了11.18%。大多数纳入研究聚焦于正畸牙齿移动（32.3%），主要使用大鼠模型（50%）。尽管美国的出版物数量最多（n = 236），但资助研究的趋势随时间呈下降轨迹，美国国立卫生研究院的资助明显有限。
本研究揭示了与动物相关的正畸研究总体呈下降趋势，其突出表现为美国国立卫生研究院的资助随时间显著减少。为弥补这一差距，学术机构和专业组织应支持促进生物医学正畸研究的举措。
