Peri-implantitis as a potential risk factor for peri-implant oral malignancy.
Review in Journal of the Korean Association of Oral and Maxillofacial Surgeons, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Peri-implant oral malignancy (PIOM) refers to malignant tumors arising around dental implants and is an increasingly reported complication of implant therapy. PIOM may follow distinct pathophysiological mechanisms, including chronic peri-implant inflammation and implant-related factors that contribute to carcinogenesis. This current review aims to explore the potential role of peri-implantitis (PI) as a risk factor for PIOM, discussing the proposed pathogenic mechanisms, histological findings, and clinical implications. A comprehensive literature search was conducted in PubMed, Scopus, and Web of Science databases. Relevant case reports, clinical studies, and reviews on the keywords "PIOM" and "PI" published from 2019 up to 2025 were included and qualitatively analyzed. Clinicopathologic characteristics are summarized as location and morphology, disease progression, histopathology, and degree of differentiation, and pathophysiological hypotheses involve inflammatory and electrochemical pathways, epithelial barrier dysfunction, molecular alterations, microbiome dysbiosis, and immune dysregulation. Current evidence remains limited and primarily anecdotal. Several studies suggest that chronic inflammation, titanium particle exposure, corrosion byproducts, and sustained tissue damage in peri-implant tissues may contribute to oncogenesis. While a direct causal link between PI and PIOM remains unproven, chronic peri-implant inflammation may contribute to malignancy development in predisposed individuals. Clinicians should consider a biopsy when peri-implant lesions exhibit atypical features, promptly.
