Accuracy of Marginal and Internal Adaptation of Advanced Lithium Disilicate Crowns Using Different Margin Designs (In Vitro Study).
Article in International journal of dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Advanced lithium disilicate glass ceramics offer excellent esthetics, but conservative crown preparations are not always the preferred choice. Various margin designs are available; however, more conservative vertical preparations (vertipreps) have less scientific evidence supporting their esthetic outcomes compared to shoulder or chamfer designs. Aim of the Study: To assess the marginal adaptation and internal fit of crowns fabricated from advanced lithium disilicate (CEREC Tessera) using computer-aided design and manufacturing (CAD/CAM) with three distinct margin designs. Materials and Methods: Three mandibular molar typodont teeth were prepared with three finish line designs: chamfer 0.5 mm (C), rounded shoulder 1 mm (RS), and vertiprep 0.2 mm (V) using a modified dental surveyor for standardization. Silicone replicas were used to create epoxy resin dies. Twenty-four crowns were produced on the replicated resin dies, with eight crowns for each finish line design ( Results: One-way ANOVA showed a significant difference in the marginal adaptation among groups ( Conclusion: The vertiprep showed the least marginal adaptation and best internal fit compared to shoulder and chamfer designs, with no significant difference in marginal gap between vertiprep and chamfer.
