Citation-based metrics, such as the H-classics method, have been used as an indicator to assess academic performance in the scientific community. However, information addressing issues regarding self-citation, citation half-life, and subject area of origin in implant dentistry is lacking. The purpose of this study was to investigate the citation characteristics of H-classics articles in implant dentistry throughout different time periods.
H-classics implant dentistry articles were searched and selected by applying the H-classics method from the Scopus database. Bibliometric analysis was conducted to evaluate the citation characteristics, including institutional and journal self-citation, citation half-life, and subject area of origin of identified H-classics articles.
The International Journal of Oral & Maxillofacial Implants and Clinical Oral Implants Research are the leading journals contributing the majority of citations to the retrieved H-classics articles. Articles published in the United States cited the most H-classics articles. Journal self-citation was 12.41% on average, while institutional self-citation was approximately 7.81%. Citation half-life decreased significantly across time periods, with an average decreasing ratio of 43.95%. Research on Scope III, bioengineering interventions, had the most prominent distribution citation frequency in the subject area "Others."
This study provides insightful views regarding citation characteristics of H-classics articles in implant dentistry (eg, interdisciplinary publications on bioengineering interventions) during the investigation periods, which may foster the translation of preclinical research into clinical applications in the future.
引文计量指标，如 H 经典法，已被用作评估科学界学术表现的指标。然而，在种植牙科领域，关于自引、引文半衰期和来源学科的信息还存在不足。本研究旨在调查不同时间段 H 经典种植牙科文章的引文特征。
通过 Scopus 数据库应用 H 经典法搜索并选择 H 经典种植牙科文章。进行文献计量分析，以评估引文特征，包括机构和期刊自引、引文半衰期和来源学科。
《国际口腔颌面种植学杂志》和《临床口腔种植研究杂志》是对检索到的 H 经典文章贡献最多引文的主要期刊。美国发表的文章引用了最多的 H 经典文章。期刊自引平均为 12.41%，机构自引约为 7.81%。引文半衰期随时间显著下降，平均下降比例为 43.95%。在“其他”主题领域，研究范围 III、生物工程干预的分布引文频率最高。
本研究提供了关于种植牙科 H 经典文章引文特征的有见地的观点（例如，生物工程干预的跨学科出版物），这可能有助于未来将临床前研究转化为临床应用。
