The Prevalence of Early Implant Failure and Associated Risk Factors: A Retrospective Study.
Review in Journal of clinical and experimental dentistry, 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
Background: This retrospective study aimed to evaluate the prevalence and associated factors of early implant failure at Maha Chakri Sirindhorn Dental Hospital, Faculty of Dentistry of Mahidol University. Material and Methods: All implant placements performed between 2016 and 2023 were collected from the hospital's database (SSB program) using specific treatment codes. Failed implants were retrieved from the claimed implant list and categorized as early or late failures based on the timing of final restoration. Early failures were selected for further analysis, with data extracted from their respective treatment records, including patient's demographic data, periodontal status, and implant's characteristics. Results: A total of 7,368 dental implants were placed, of which 114 failed before final restoration and were subsequently removed. The prevalence of early implant failure was 1.55%. Univariate analysis revealed associations between early implant failure and a history of periodontitis, diameter of implant, location of implant placement, level of implant platform as determined by radiographic analysis, covering materials of implants. Moreover, length of implant was also having a trend toward association with early implant failure (p=0.052). From multivariate logistic regression analysis, only diameter (p=0.003) and length of implant (p=0.022) were associated with early implant failure. Conclusions: Our findings suggest that implant diameters less than 3.5 mm and lengths less than 10 mm are associated with an increased risk of early implant failure. Further research is warranted to clarify the influence of other potential contributing factors.
