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

backgroundDigital technology has been applied in the field of oral surgery. In this study, the efficacy of custom-made surgical guides for the removal of supernumerary impacted teeth in the maxilla was investigated.

methodsThe surgical guides were designed with access holes and rods that corresponded to the positions of the impacted teeth and the direction of the approach. The biocompatibility of the 3D-printed materials was first assessed in vitro. The efficacy of the printed surgical guides was evaluated in an in vitro experimental model study performed by 32 oral surgeons on 3D-printed maxillary models to evaluate various surgical parameters and complications, and a clinical observation study of 30 patients.

resultsThe 3D-printed materials demonstrated excellent biocompatibility when they were fabricated according to the manufacturer’s protocol. In the in vitro study, the guides did not significantly reduce the extraction time or bone removal volume compared with those of the control group. However, they effectively prevented mispositioning of bone removal sites and reduced the incidence of root damage. Clinically, all surgical guides resulted in safe and precise bone removal without major complications.

conclusionsThe benefit of the surgical guide system used in the present study showed limited, but it might minimize complications and enhance the safety during supernumerary impacted tooth removal.
