The clinical use of zirconia implants has been shown to increase steadily due to their biological, aesthetic, and physical properties; therefore, this bibliometric study aimed to review the clinical research and co-authors in the field of zirconia dental implant rehabilitation.
We searched Scopus and Web of Science databases using a comprehensive search strategy to 5 October 2020, and independently paired reviewers who screened studies, and collected data with inclusion criteria restricted to clinical research only (either prospective or retrospective). Data on article title, co-authors, number of citations received, journal details, publication year, country and institution involved, funding, study design, marginal bone loss, survival rate, failure, follow-up, and the author's bibliometric data were collected and evaluated.
A total of 29 clinical studies were published between 2008 and 2020 as 41.4% were prospective cohort studies and 48.3% originated from Germany. Most of the included studies had been published in Clinical Oral Implant Research ( = 12), and the most productive institution was the Medical Center of University of Freiburg. The author with the largest number of clinical studies on zirconia implants was Kohal R.J. ( = 10), followed by Spies B.C. ( = 8).
This study revealed that zirconia implants have been more prominent in the last ten years, which is a valuable option for oral rehabilitation with marginal bone loss and survival rate comparable to titanium dental implants.
由于氧化锆种植体具有生物学、美学和物理特性，其临床应用呈稳步增长趋势；因此，本文献计量学研究旨在回顾氧化锆牙种植体修复领域的临床研究及共同作者情况。
我们采用全面检索策略，在Scopus和Web of Science数据库中检索至2020年10月5日，并由独立配对的评审员筛选研究，收集纳入标准仅限于临床研究（前瞻性或回顾性）的数据。收集并评估文章标题、共同作者、引用次数、期刊详情、出版年份、涉及的国家和机构、资金、研究设计、边缘骨吸收、生存率、失败情况、随访以及作者的文献计量学数据。
2008年至2020年间共发表了29项临床研究，其中41.4%为前瞻性队列研究，48.3%来自德国。大多数纳入研究发表于《临床口腔种植研究》（12篇），产出最多的机构是弗莱堡大学医学中心。关于氧化锆种植体临床研究数量最多的作者是Kohal R.J.（10篇），其次是Spies B.C.（8篇）。
本研究表明，氧化锆种植体在过去十年中更为突出，对于边缘骨吸收和生存率与钛牙种植体相当的口腔修复而言，是一个有价值的选择。
