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

BACKGROUNG/

aimNew resins for the additive manufacturing of mouthguards for contact sports are now available on the market. However, no study has evaluated the impact performance of these resins. The aim of this in vitro study was to compare the shock absorption capacities of custom-made mouthguards produced by additive manufacturing with those of thermoformed mouthguards. MATERIALS AND

methodsThree types of custom-made mouthguards were fabricated: 3D-printed Keyguard and Dima resin mouthguards and thermoformed triple-layer mouthguards. For each type of mouthguard, eight samples were produced. Each mouthguard was subjected to an impact performance test defined by the NF S72-427 standard for industrial mouthguards. Mean transmitted deceleration must not exceed 230 g (g = 9.81 m/s

resultsNone of the mouthguards met the impact absorption standard. Thermoformed mouthguards exhibited major structural failure after the first impact. For 3D-printed mouthguards, average peak deceleration ranged from 255 to 278 g for Dima and 292 to 299 g for Keyguard. Corresponding transmitted forces ranged from 2753 to 3106 N (Dima) and 3192 to 3292 N (Keyguard), with no significant difference between the two 3D-printed mouthguards (p > 0.05). Mean thickness decrease at the impact site was 0.2 mm for Dima mouthguards, 0.1 mm for Keyguard mouthguards, and 0.3 mm for thermoformed mouthguards.

conclusionAlthough none of the tested mouthguards met the NF S72-427 standard, 3D-printed custom devices demonstrated promising shock absorption performance after repeated impacts. These results highlight the potential of additive manufacturing as a cost-effective alternative to conventional thermoformed mouthguards, particularly for younger athletes requiring frequent replacements.
