Polytetrafluoroethylene (PTFE) Tape as a Screw-Access Sealing Material in Implant-Supported Crowns.
Article in Cureus, 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
A clear consensus is lacking in the literature regarding the optimal material for sealing the screw‑access channel in implant‑supported restorations. Commonly used materials, including cotton pellets, polyvinyl siloxane, and gutta‑percha, are selected largely based on clinician preference rather than evidence‑based guidelines. Polytetrafluoroethylene (PTFE) tape has emerged as a practical alternative, offering several advantages for sealing the screw‑access channel in screw‑retained implant crowns. PTFE is inexpensive, readily adaptable, easy to manipulate, and maintains dimensional stability even after sterilization. Furthermore, it facilitates efficient screw access during maintenance procedures without compromising the protection of the abutment and prosthetic screw. This technical report describes a straightforward technique in which PTFE tape is utilized as a screw‑access sealing material for screw‑retained implant‑supported crowns, providing clinicians with a reliable and retrievable option for prosthetic management.
