Managing Zygomatic Implant Failure With Pterygomaxillary Implant and Sinus Floor Elevation: A Technical Note.
Article in The Journal of craniofacial surgery, 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
This report describes a safe and staged protocol for managing the failure of a zygomatic implant complicated by severe sinusitis, using a pterygomaxillary implant and subsequent sinus floor elevation with intermediate implant placement. A 67-year-old male presented with a failed right zygomatic implant and refractory sinus infection 11 months after full-arch maxillary rehabilitation. After sectioning the zygomatic implant at the inferior border of the zygomatic arch, the authors inserted a pterygomaxillary implant and subsequent sinus floor elevation with intermediate implant placement to support a new restoration. The protocol successfully resolved the sinus infection and maintained prosthetic function throughout treatment. The final prosthesis, supported by the pterygomaxillary implant, the new intermediate implant, and the remaining stable implants, demonstrated good stability at the 1-year follow-up. Further long-term studies are needed to comprehensively evaluate the protocol's efficacy and stability.
