Effect of Total Crown and Veneer Zirconia Meso-Structure Designs on Anterior Implant-Supported Restorations: A 3D Finite Element Analysis.
Review in Journal of clinical and experimental dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Unfavorable implant positioning in esthetic zones may result in buccal or incisal emergence of the prosthetic screw access, requiring alternative restorative strategies. This study evaluated, by three-dimensional finite element analysis (FEA), the effect of total crown and laminated veneer zirconia meso-structure designs cemented onto a titanium base (Ti-base) on stress distribution and bone microstrain. Material and Methods: Two zirconia meso-structure designs: total crown (TC) and laminated veneer (LV) were simulated on a Ti-base using previously validated models. A 20 Ncm screw torque and a 150 N oblique load at 30° were applied. Stress was analyzed using von Mises and maximum principal stress, and bone response by microstrain. Results: Both designs showed similar stress distribution in the implant, Ti-base, and screw. Microstrain concentrated mainly in the peri-implant cortical bone, with slightly wider distribution in the LV model. Conclusions: TC and LV meso-structures exhibited comparable biomechanical behavior, suggesting that their selection may be guided primarily by restorative and esthetic considerations.
