Effect of implant protrusion length on intrasinus bone formation in transalveolar sinus lift without grafting: a meta-analysis.
Article in Annals of medicine and surgery (2012), 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: Transalveolar sinus floor elevation (TSFE) without bone grafting has gained attention as a minimally invasive approach for vertical bone augmentation in the atrophic posterior maxilla. Although implant protrusion length (IPL) is theorized to be a key determinant of intrasinus bone gain, the existing evidence is inconsistent. Objective: The purpose of this systematic review and meta-analysis is to evaluate the effect of IPL on intrasinus bone gain following transalveolar sinus floor elevation performed without bone graft materials. Methods: Electronic searches were conducted in PubMed/Medline, Scopus, Web of Science, and Science Direct until December 2024. Randomized controlled trials, cohort studies, and retrospective analyses reporting IPL and vertical bone gain (VBG) were included. Data were pooled using random-effects meta-analysis, with subgroup analyses by IPL categories (<3 mm, 3-5 mm, >5 mm). Results: Twelve studies (519 implants) met inclusion criteria. Meta-analysis revealed a significant positive association between IPL and VBG (WMD: 1.85 mm, 95% CI: 1.12-2.58; * Conclusion: Controlled implant protrusion (3-5 mm) optimizes bone formation in graft-free TSFE, offering a biologically driven alternative to graft-dependent approaches. Standardization of IPL measurement protocols and long-term implant survival studies are warranted to refine clinical guidelines.
