Searches were performed in PubMed, Scopus, Google Scholar, and the NLM Catalog from 1900 to June 2025. The Scopus dataset was imported into CiteSpace to generate keyword frequency and burst analyses, which guided secondary searches in PubMed and Scopus for orthodontics-related articles published in non-orthodontic medical and dental journals. Bibliometric studies were retrieved using targeted queries and by manual cross-referencing of references. Duplicate removal was performed manually in MS Excel by the author with the assistance of a statistician and a librarian, and validated using CiteSpace preprocessing.

Across the century, 83 orthodontic journals were identified, of which 26 remain active and indexed (PubMed = 17; Scopus = 26). Output increased from fewer than 4,000 publications during 1915–1950 to more than 13,000 during 2011–2020, with nearly 7,000 already indexed in 2021–2025. Trends showed a transition from descriptive reports to randomized controlled trials, systematic reviews, and umbrella reviews. Authorship networks confirmed globalization, with growing contributions from Asia, Latin America, and the Middle East. Thematic mapping highlighted rapid growth in digital workflows, aligners, artificial intelligence, and patient-reported outcomes.</div></div><div><h3>Conclusion</h3><div>Orthodontic publishing has evolved from localized descriptive accounts to globally networked, digitally disseminated, and evidence-based scholarship.

It's the opposite of reasoning by analogy (e.g. Orthodontic cases). Rather than relying on rote techniques, empirical guesses, or trendy gadgets that often introduce unnecessary complexity and failure risks, the paper urges clinicians to break down tooth movement and treatment challenges to their atomic fundamentals (e.g., Newton's laws of equilibrium, friction, force vectors, biological remodeling, and quasi-static systems) and rebuild solutions logically from there.

This process underlies both the efficiency of tooth displacement and associated risks such as root resorption. Excessive force application disrupts physiological equilibrium, leading to tissue hyalinization, sterile inflammation, and increased odontoclast activity that compromises root integrity. Conversely, emerging biological strategies enable acceleration of OTM through surgically facilitated techniques like micro-osteoperforations that induce regional accelerated phenomenon (RAP), or through non-invasive adjuncts including photobiomodulation that enhance cellular responses. Given significant individual variability in biological response, personalized treatment approaches utilizing optimized force regimens and targeted interventions are essential for balancing treatment efficiency with periodontal safety. Future advances may incorporate biomarker-guided force adjustment and localized biological modifiers to further refine tooth movement control. Integration of these mechanobiological principles into clinical practice promises to transform orthodontics into a more predictive, efficient, and biology-driven discipline.</div></div>","PeriodicalId":48688,"journal":{"name":"Seminars in Orthodontics","volume":"32 2","pages":"Pages 338-347"},"PeriodicalIF":2.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146192962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This manuscript frames that trajectory as a sequence of scientific-revolution stages—pre‑science, normal science, model drift, model crisis, and model revolution—to clarify how conceptual and technological shifts have reshaped clinical practice and research priorities. We synthesize developments in digital workflows (intraoral scanning, CBCT integration), AI‑driven treatment staging, and personalized biomechanics, and we evaluate methodological limitations in current CAT studies that hinder reliable data interpretation. Key gaps include inconsistent outcome definitions, limited external validity of small or vendor‑sponsored trials, insufficient biomechanical and materials characterization, and sparse patient‑centered endpoints. These limitations inflate uncertainty around dose–response relationships, material behaviour under clinical conditions, and the real‑world effectiveness of algorithmic staging tools. To enhance evidence quality and patient outcomes, we propose stronger research designs—prospective, adequately powered, multi-center trials; standardized outcome metrics; preregistration and transparent data sharing; robust biomechanical and materials testing; and integrated health‑services research to assess access, costs, and patient preferences. We also advocate development and validation of AI‑assisted decision‑support tools within rigorous clinical frameworks. Multidisciplinary, methodologically rigorous research and consensus on outcomes are essential to translate digital innovations in CAT into predictable, patient‑centred care.
