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

Temporary anchorage devices (TADs) provide maximum anchorage in orthodontic therapy. Surgical guides can be used to accurately achieve pre-planned TAD positions. The objective of this study was to assess the accuracy of guided TAD insertion in the anterior palate, comparing two 3D printed surgical guide designs. Patients were randomized in two groups. TADs were inserted using either a surgical guide with a skeletonized design or full arch design. The primary outcome was translational and rotational deviations from the virtually planned TAD positions. Secondary outcomes included the dependence of deviations on age and gender and TAD success rate after a follow-up period of three months. In total 40 patients were included in this RCT and 80 TADs were inserted. During the follow-up period, no TAD loss was observed. The skeletonized design showed significantly higher deviations between the planned TAD position and the actual TAD position in all, but two spatial dimensions (translational and rotational) compared to the full arch design. The right TAD showed higher deviations compared to the left TAD for the skeletonized design. The full arch design showed significantly higher accuracy compared to the skeletonized design. During virtual planning of TAD positions, a safety distance should be considered to account for possible deviations using 3D printed surgical guides for TAD insertion in the anterior palate.
