Prevalence of caries in teeth adjacent to implant-supported prostheses and relationship with implant location and the manner of restoration placement: a retrospective cohort study.
Article in Clinical oral investigations, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
objectivesThe primary objective of this study was to analyze the overall prevalence of caries in teeth adjacent to implant-supported protheses (ISPs). Secondary objectives were to determine how different implant restoration placement options (direct to implant, intermediate abutment, or Ti-Base) and/or ISP location influence the occurrence of caries. MATERIALS AND
methodsThis retrospective cohort study was performed at the University Clinic of King Juan Carlos University (URJC, Madrid, Spain), between January 2018 and December 2023, following strict inclusion and exclusion criteria. Both single crowns and fixed partial dentures supported by implants were included. Descriptive statistics were calculated for the relevant variables. Associations between different groups (direct to implant, Ti-base, and intermediate abutment) were analyzed.
resultsThe study evaluated 445 implant-supported protheses in 359 patients. The overall prevalence of caries in teeth adjacent to ISPs at patient level was 8.9% (95% CI: 5.95% to 11.84%) and 8.1% (95% CI: 5.56% to 10.63%) at prothesis level. Prevalence was higher in the molar region (9.6%; 95% CI: 5.7% to 13.4%), followed by premolar sites (8.6%; 95% CI: 4.2% to 12.9%). The highest prevalence of caries was found in teeth adjacent to ISPs placed direct to implant (11.4%; 95% CI: 7.3% to 15.4%); followed by teeth adjacent to implants restored with Ti-Base (10.5%; 95% CI: 0.0% to 24.2%). Those teeth adjacent to implants restored using intermediate abutments had the lowest prevalence (3.7%; 95% CI: 1% to 6.3%). Statistically significant differences between restoration groups were observed (p = 0.013). Moreover, the odds of caries increased by 3.37 times in teeth adjacent to ISPs placed direct to implant compared with those restored with intermediate abutments.
conclusionsThe prevalence of caries in teeth adjacent to ISPs is significantly higher in implants restored direct to implant compared with those restored with intermediate abutments. CLINICAL RELEVANCE: Selecting the appropriate implant-supported restoration placement option may reduce caries in teeth adjacent to an ISP. Intermediate abutments would appear to reduce the risk of caries compared with direct implant restorations.
