1 · What the graph read from it

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.

2 · The registry

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 present study explored the trueness of active robotic system-assisted cortical-window osteotomy and tooth sectioning relative to conventional freehand surgery, employing a labial approach to remove impacted maxillary midline supernumerary teeth. Standardized three-dimensional maxillary replicas containing an impacted midline supernumerary tooth were randomized into an Active Robot-assisted Group (ARG) or a Freehand Group (FHG). Preoperative CBCT and intraoral scans were merged to plan osteotomy and tooth sectioning trajectories. Parameters analyzed included cortical-window formation and tooth segmentation trueness, bone injury, and operative duration. The ARG achieved significantly higher Dice similarity coefficients (0.93 vs. 0.71, p < 0.001) and lower centroid deviations (0.31 mm vs. 1.15 mm, p < 0.001) than the FHG. Both excessive and insufficient bone removal were markedly reduced in the ARG group (p < 0.001). The root mean square (RMS) deviation (0.19 mm vs. 0.96 mm, p < 0.001) and angular deviation (5.70° vs. 17.90°, p < 0.001) were significantly smaller in the ARG group, while the depth of bone injury was lower (0.00 [0.00-0.77] vs. 0.87 [0.45-1.51], p = 0.039), and the operative duration was slightly longer (160 s vs. 132 s). Robot-assisted extraction of impacted maxillary midline supernumerary teeth demonstrated greater trueness and reduced collateral bone injury than conventional freehand surgery. The robotic system enhanced surgical safety, reproducibility, and trueness. These in vitro findings demonstrate the technical feasibility of active robotic systems for minimally invasive, high-trueness extraction of supernumerary teeth.
