Oral Squamous Cell Carcinoma Associated with Dental Implants: A Literature Review with Focus on Field-Cancerized Mucosa.
Review in Cancers, 2025. 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
backgroundThe oncologic safety of dental implants (DIs) in patients with oral field cancerization (OFC) remains uncertain. Increasing reports of oral squamous cell carcinoma (OSCC) developing adjacent to DIs have raised concerns regarding the interaction between implants, chronic inflammation, and genetically altered mucosa.
methodsA comprehensive PubMed/MEDLINE search was performed through June 2025 to identify English- or Spanish-language publications reporting primary OSCC occurring in proximity to DIs. Extracted variables included patient demographics, tumor site, clinical presentation, presence of oral potentially malignant disorders (OPMD) or prior OSCC, peri-implant inflammation, management, and outcomes. Cases describing clinical features compatible with field-altered mucosa (e.g., OPMD or prior OSCC) were evaluated descriptively, recognizing that formal histopathologic or molecular evidence of OFC was rarely reported.
resultsA total of 105 implant-associated OSCC cases were identified. The mean patient age was 66.8 years (range: 40-90), with a female predominance (1.3:1). The mandible was the most frequently involved site (86.7%). A prior history of OPMD or OSCC was reported in 53 patients (50.5%), and peri-implantitis preceding diagnosis in 21 cases (19.0%). The most common clinical presentations were exophytic (59.0%) and ulcerated (37.1%) lesions, frequently mimicking peri-implantitis and contributing to diagnostic delay. Reported outcomes included recurrence in 11 cases (10.5%) and death in 13 cases (12.4%).
conclusionsCurrent evidence suggests that implant-associated OSCC frequently occurs in patients with pre-existing mucosal alterations and may be influenced by the interaction of field cancerization with local inflammatory and mechanical factors. Implant rehabilitation in individuals with OPMD, prior OSCC, or epithelial dysplasia should be undertaken cautiously, with rigorous long-term surveillance to ensure oncologic safety.
