In vitro comparison of different composite resins for aligner attachment production : Amount of adhesive flash, flash removal time, and shear bond strength.
Article in Journal of orofacial orthopedics = Fortschritte der Kieferorthopadie : Organ/official journal Deutsche Gesellschaft fur Kieferorthopadie, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
introductionThe aim of this in vitro study was to determine the difference between aligner attachments constructed from four different composite resins in terms of adhesive flash amount, removal time, and shear bond strength. MATERIALS AND
methodsIn all, 80 extracted human premolars were divided into four groups (N = 20) based on the type of composites used for the fabrication of aligner attachments (Group 1: GC Aligner Connect and Group 2: GC Ortho Connect [both from GC Dental Products, Tokyo, Japan]; Group 3: Z350 XT flowable and Group 4: Filtek Z350 XT Universal [both from 3M Unitek, Monrovia, CA, USA]). After bonding, the attachments were scanned with the iTero Element® (Align® Technology, San Jose, CA, USA). The amount of adhesive flash in the overflowing areas was analyzed by comparing the bonded attachments before and after removing the adhesive flash via the software 3D Geomagic Control (3DS Systems, Rock Hill, SC, USA). A color map was used to reveal the percentage of overflowing resin. Flash adhesive removal time per tooth and shear bond strength of the attachments were also analyzed. The significance level was set at p < 0.05.
resultsThe median values for the overflowing flash adhesive (surface deviation values) were 0.26, 0.29, 0.35, and 0.26 mm for Groups 1, 2, 3, and 4, respectively, with a significant difference between the groups (3 > 1, 2, 4; p < 0.001, effect size (η
conclusionZ350 XT flowable composite showed a higher overflow value and percentage of color deviation than the attachments made from the other resins. The universal restorative resin Filtek Z350 XT Universal was found to be advantageous in terms of both causing less flash adhesive and demonstrating higher bond strength to the tooth.
