Internal and marginal adaptation of 3D printed interim fixed partial dentures with different layer thicknesses.

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 study was to compare the marginal and internal adaptation of polymethyl methacrylate interim fixed partial denture (FPD) restorations fabricated by three-dimensional (3D) printing with different layer thicknesses. MATERIALS AND
methodsA standard typodont was scanned by a laboratory scanner. The maxillary left first premolar and first molar teeth received an all-ceramic full-coverage crown preparation, and the second premolar was removed to create a pontic space. The prepared teeth were then scanned, and metal dies were fabricated by a milling machine. Restorations were designed and fabricated in 3 groups (n = 12 in inch) with 25, 50 and 100 µm layer thicknesses. The marginal and internal gaps were measured by the replica technique. Data were analyzed by one-way ANOVA (α = 0.05).
resultsThe mean gap size (MGS) in the cervical area of premolar restorations was significantly higher in 100 µm than in 50 and 25 µm thicknesses (
conclusionDifferent thicknesses of additive layers in 3D printing affected the marginal and internal gaps. The smallest gap size was recorded in 50 µm layer thickness.
