doi:10.13701/j.cnki.kqyxyj.2025.10.006

Abstract

Abstract: Objective: To explore the current status, research hotspots, and development trends of zirconia ceramics in posterior implant restorations in the past two decades (2004-2024). Methods: Literature from 2004 to 2024 was retrieved from the Web of Science Core Collection. VOSviewer 1.6.20 and CiteSpace 6.1.R2 were used to conduct retrospective bibliometric analysis and generate visual maps of author collaboration, keyword co-occurrence, and topic evolution. Results: A total of 95 articles from 22 countries and 131 institutions were included. The number of publications increased significantly after 2012. Frequent keywords indicated a strong focus on mechanical properties, esthetic performance, and digital manufacturing. Topic evolution showed a shift from material-focused studies to clinical outcomes, particularly the performance and long-term survival of monolithic zirconia restorations. The co-citation publications mainly focuses on systematic reviews and clinical trials, focusing on restoration strength, aesthetic durability and complication control, which are the core components of the knowledge structure in this field. International collaboration remains limited, with Chinese research mostly conducted by single institutions. Conclusion: Zirconia ceramics has become a key material for posterior implant restorations. Future studies should focus on wear behavior, esthetic optimization, and long-term clinical performance, along with strengthened global collaboration and technological integration.
