Enhancing the accuracy of full-arch digital implant impressions via segmentation: An in vitro study.

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.
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
purposeThe aim of this in vitro study was to assess whether the accuracy (trueness and precision) of full-arch implant digital impressions can be improved by replacing standard digital impressions (StDIs) with segmented digital impressions (SgDIs), obtained by superimposing short-span digital impressions using a geometric pattern. MATERIALS AND
methodsThe study was conducted using a commercial edentulous maxillary model with four implants-positioned at the sites of the canines and second molars-and four commercial intraoral scan bodies (ISBs) screwed to them. Ten StDIs and SgDIs of the model were obtained, and their accuracy was evaluated and compared in terms of trueness and precision, based on measurements of three distances and three angles between the ISBs.
resultsThe results of this study indicated that the SgDIs were significantly more accurate than the StDIs. The trueness and precision of the three distances measured in the SgDIs were better than those of the distances measured in the StDIs, in a statistically significant way. The trueness and precision of the angles measured in the SgDIs were, in general, also better than those of the angles measured in the StDIs, but in this case the differences were not statistically significant for all the measured angles.
conclusionsBased on the results of this study, it was concluded that improving the accuracy of full-arch digital implant impressions through segmentation is feasible, even showing that accuracy values compatible with a passive fit of implant-supported full-arch prostheses can be achieved.
