More Than Anchors: Evidence for Screw-Mediated Osseointegration in Customised Subperiosteal Implants for Severe Maxillary Atrophy - a Case Report.
Article in Maedica, 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
Objectives: To describe the digital planning, fabrication and clinical outcome of a customised subperiosteal implant used to rehabilitate a severely atrophic edentulous maxilla, and to propose a comparative, quantitative framework for evaluating the bone-titanium contact surface generated by the screw-fixation system, in support of the hypothesis that these screws contribute a genuine osseointegrative component to implant stability, beyond their acknowledged mechanical role. Materials and methods: We report the case of a 63-year-old female patient with total maxillary edentulism and severe bone atrophy, treated with a digitally designed, CAD/CAM-manufactured titanium subperiosteal implant anchored by 27 osteosynthesis screws (2 mm diameter, 7 mm length). The cumulative bone-titanium contact surface generated by the fixation screws was compared, using the formula S = π × d × h, with that of a conventional restoration supported by eight endosseous implants (4 mm × 8 mm). Results: The comparative analysis showed a larger cumulative contact surface for the screw-fixation system (≈1068.7 mm²) than for the endosseous alternative (≈804.2 mm²). Clinical and radiological stability was maintained beyond one year of follow-up, without signs of implant mobility or peri-implant inflammation. Conclusions: The findings of the present study support the hypothesis that osteoinductive and osseointegrative processes contribute meaningfully to the long-term success of modern subperiosteal implants, in addition to the mechanical retention provided by the fixation screws.
