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

objectivesBalancing the aesthetic and mechanical effects remains challenging in terms of attachments. This study proposed a strategy by introducing laser surface texturing in clear aligners fabrication to enhance the retention and grip of clear aligners and minimize the size of attachments. MATERIALS AND

methodsA grid pattern with a spacing of 1 mm on the surface of thermoplastic polyurethane substrate was textured using a CO

resultsTPU after laser surface texturing exhibited increased roughness, and therefore enhanced the retention and gripping force of LST-modified clear aligners. Although the average transmittance of the LST-modified TPU was 2.32% lower, LST had little negative effect on aesthetic of aligners.

conclusionsLaser surface texturing, as a novel auxiliary approach in aligners fabrication, has the potential to enhance mechanical properties such as roughness, retention and force delivery of TPU-fabricated clear aligners. CLINICAL RELEVANCE: The mechanical enhancement of LST-modified clear aligners could have a better control on teeth movements and reduce the sizes of attachments without sacrificing their mechanical effect, helping to balance the aesthetics and mechanic effects of attachments.
