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

backgroundThe traction of an impacted canine is complicated and challenging due to its position, direction, relationship to adjacent teeth and anchorage design. This study describes a customized device for the three-dimensional traction of complex maxillary impacted canines (MICs). CASE PRESENTATION: This article reports two cases of young patients with complex MICs (Case Ⅰ: the MIC has high horizontal impaction without enough adjacent anchorage teeth, and Case II: the crown of the MIC is entirely embedded between the roots of adjacent incisors). A digitally customized device was developed to optimally resolve impaction management challenge in both patients. The therapeutic effects are evaluated by comparing the pretreatment, during-treatment and posttreatment results, including those from clinical and imaging examinations. After traction using the customized device, the impacted canines were successfully repositioned in the dental arch, and both the anchoring teeth and adjacent teeth were in good condition, which established a robust foundation for subsequent stage. Then, after fixed orthodontic treatment, both patients exhibited good dental alignment.

conclusionsThe satisfactory clinical outcome demonstrated that the customized device is convenient, comfortable, safe, and excellent in 3D control for the traction of MIC; in conjunction with fixed orthodontic techniques, it can effectively accomplish comprehensive orthodontic treatment for MIC.
