Influence of printing orientation on the accuracy, fit and mechanical properties of 3D-printed full-coverage prostheses: a systematic review.
Review in Frontiers in oral health, 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
Aim: This systematic review evaluated the influence of 3D printing orientation on the mechanical properties, accuracy, and marginal fit of full-coverage dental prostheses. Materials and methods: A comprehensive search was conducted through PubMed, Embase, Scopus, and Web of Science databases for Results: About 20 studies were included. Printing orientation significantly affected mechanical properties, including flexural and compressive strength, particularly in vertically or obliquely oriented specimens, whereas microhardness, density, and porosity were less influenced. Trueness and precision were significantly improved by printing orientation angles such as 0°, 30°, and 45°, while the greatest deviations were reported at 45°, depending on prosthesis type, tooth morphology, and printer system. Marginal fit was highly dependent on experimental conditions, with no universally optimal printing angle identified. Conclusion: Overall, printing orientation plays a critical role in the functional and dimensional performance of 3D-printed dental prostheses. Oblique orientations generally provide a favorable balance between mechanical strength and accuracy.
