One-year marginal bone loss and survival rate of triangular-neck dental implants: a systematic review and meta-analysis.
Synthesis in International journal of implant 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
purposeThis systematic review aimed to evaluate the clinical performance of dental implants with a triangular neck, focusing on 1-year marginal bone loss (MBL) and implant survival rate.
methodsThis review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search of databases (PubMed, Scopus, and Web of Science) was completed on June 8, 2025. Randomized controlled trials (RCTs), retrospective and prospective studies, and case series that studied ≥ 10 implants, reporting on triangular-neck implants, were included. The Cochrane risk of bias 2 tool was used for RCTs, and the Joanna Briggs Institute case series checklist was used for nonrandomized studies. The results were summarized using a random-effects meta-analysis and sensitivity analysis was performed to assess robustness. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method was used to determine the certainty of evidence.
resultsThe search provided 115 titles after removal of duplicates. Eight studies met the inclusion criteria, five of which provided sufficient data for quantitative synthesis. The pooled analysis demonstrated a 1-year mean MBL of 0.35 mm (95% confidence interval [CI]: 0.24-0.46; heterogeneity; I
conclusionsAvailable single-arm evidence indicates that triangular-neck implants were associated with high implant survival rates and limited marginal bone level changes during the first year of follow-up. However, the current evidence does not permit conclusions regarding comparative clinical benefits relative to other implant designs.
