Accuracy of Facial Digitization Using a New Mobile Device-Compatible 3D Scanner for Malocclusion.
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
The three-dimensional (3D) facial scanning system plays a crucial role in orthognathic surgery, with significant advancements in related technologies. However, high costs and limited portability have restricted the accessibility of existing scanners, highlighting the need for a mobile device-based 3D facial scanning system. To address this, a new mobile device-compatible 3D facial scanning software (i3Dface) was developed, installed, and tested on mobile tablets. From August 2021 to December 2022, 50 volunteers participated in evaluating i3Dface's reproducibility and accuracy for facial digitization and orthognathic applications. i3Dface demonstrated strong reproducibility in environments with optimal light intensity (600-2100 lux) and shooting angles (-20 degrees-10 degrees). When comparing absolute deviations in facial measurements, i3Dface showed no significant difference from the established stereophotogrammetry system (3dMD), aligning closely with manual clinical measurements. In assessing 3D spatial deviation, i3Dface's accuracy varied by facial region, with the highest accuracy (0.59 ± 0.13 mm) in the chin area and the lowest (1.17±0.16 mm) in the midface. For clinical applications in orthognathic surgery, i3Dface facial images showed effective alignment with CBCT soft tissue images. In summary, i3Dface offers reproducibility in suitable environments and accuracy comparable to 3dMD, meeting essential clinical requirements and supporting digital technology use in orthognathic surgery.
