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

backgroundAccurate extraction of impacted teeth remains a technically demanding procedure. This study aimed to develop a model-based experimental protocol to assess the surgical accuracy of a dynamic navigation system (DNS) assisted extraction of impacted maxillary anterior teeth.

methodsA standardized custom model simulating impacted maxillary supernumerary teeth was constructed. Preoperative planning, including the definition of osteotomy boundaries and tooth sectioning planes, was performed using integrated intraoral scanning and cone-beam computed tomography (CBCT) data. During surgery, the DNS guided critical surgical procedural steps, including tooth localization, osteotomy, and segmentation. Postoperative CBCT imaging was used to compare actual surgical outcomes with the preoperative plan by quantifying three-dimensional deviations. Outcome measures included root mean square (RMS) deviation, angular deviation, and other geometric discrepancies. Total osteotomy area and operative time were also recorded.

resultsFourteen models were evaluated, with seven assigned to the DNS-assisted group and seven to the control group. Compared with the preoperative plan, the DNS group demonstrated significantly lower RMS deviation in segmentation plane accuracy than the control group (0.43 ± 0.18 mm vs. 0.85 ± 0.38 mm; P = 0.02). Angular deviation was reduced in the DNS group (8.97° vs. 14.76°; P = 0.04), along with curvature RMS (1.72 rad vs. 3.54 rad; P = 0.04) and maximum deviation (0.77 mm vs. 1.30 mm; P < 0.01). DISCUSSION: These results indicate that DNS-assisted extraction of impacted maxillary anterior teeth significantly enhances surgical accuracy compared with conventional techniques, improving procedural accuracy, stability, and overall safety.
