Digitized thermo-responsive shape memory matrix band for tooth restorations.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Direct resin restoration has been widely used to restore the tooth defect for its convenience and minimal invasion. However, the accuracy of the final contour of class II restoration is often unpredictable and quite technique-sensitive due to the limitation of traditional matrix band system. In this study, the authors developed a novel matrix band system using shape memory polymer (SMP), which possessed two reversible shapes including digitized permanent shape to reproduce anatomical proximal contour and programmable temporary shape for clinical practice and reservation. The permanent shape could be designed and customized in software or retrieved from imaging database collected from large general population. Only warm saline or water was needed to trigger the shape transformation without any auxiliary tools. The results of in vitro class II restoration showed the shape memory matrix bands brought the best proximal profile and contact point, compared to traditional metal matrix and sectional matrix. The novel shape memory matrix system represents the comfortable, precise, and minimally invasive trend of dentistry and has a broad industrialization prospect as a dental instrument.
