Global research trends of peri-implantitis during the last two decades: a bibliometric and visualized study

Peri-implantitis is one of the most prevalent and impactful complications of dental implant prostheses. This study aimed to identify area focuses and emerging trends in peri-implantitis research. A literature search was conducted in the Web of Science Core Collection (WoSCC), employing a bibliometric approach for data evaluation. VOSviewer and CiteSpace software were used for identifying and analyzing research foci and trends. Between 2001 and 2020, there were 2,346 publications on peri-implantitis. Leaders in number of articles published and collaboration networks were USA and Europe. High-frequency keywords included periodontitis, treatment, prevalence, titanium, follow-up, survival, in vitro, and bone loss. Keyword burst detection analysis revealed epidemiology, outcomes, and impact as emerging research hotspots. The findings suggest a need for more international multicenter clinical studies on peri-implantitis, with future studies likely focusing on prevalence, treatment, and predisposing factors.
