Guided Bone Regeneration for Vertical Alveolar Augmentation: Clinical Evaluation of d-PTFE-Ti Membranes and Comparison with Collagen Membranes: A Systematic Review.
Review in Journal of functional biomaterials, 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
Based on the growing use of guided bone regeneration (GBR) for implant rehabilitation in atrophic alveolar ridges, the choice of barrier membrane remains a critical factor for clinical success. This review aimed to evaluate the clinical effectiveness of titanium-reinforced dense polytetrafluoroethylene (d-PTFE-Ti) membranes compared with resorbable collagen membranes in vertical ridge augmentation. A literature review was conducted using PubMed, Cochrane Library, and ScienceDirect databases. Clinical studies published since 2014 involving human subjects undergoing GBR procedures with either d-PTFE-Ti or collagen membranes were included. Nine studies met the inclusion criteria, including randomized clinical trials and cohort studies. The selected studies indicated that both membrane-based approaches were effective in promoting bone regeneration and enabling implant placement. Titanium-reinforced d-PTFE membranes may offer mechanical advantages in space maintenance and dimensional stability, particularly in larger vertical defects; however, the available comparative evidence did not demonstrate a consistent statistically significant superiority over collagen-based approaches. Within the limitations of the available evidence, both strategies appear to provide clinically predictable outcomes, and membrane selection should be individualized according to defect morphology and treatment requirements.
