Comparison of patients' oral health-related quality of life and chewing efficiency between conventional and 3D-printed complete dentures: A crossover clinical trial.
Article in Journal of dental research, dental clinics, dental prospects, 2025. 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: Additive manufacturing has introduced novel materials and workflows for complete denture fabrication; however, high-quality clinical evidence comparing patient-centered outcomes of 3D-printed and conventionally fabricated dentures remains limited. This compared oral health-related quality of life (OHRQoL) and chewing efficiency between conventional and 3D-printed dimethacrylate-based resin complete dentures. Methods: Twenty completely edentulous patients were enrolled in this randomized two-period crossover clinical trial. Each participant received both interventions-conventional complete dentures and 3D-printed dimethacrylate-based resin complete dentures-in a randomized sequence. OHRQoL was assessed using the Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT), and chewing efficiency was evaluated using a two-colored chewing gum mixing ability test by calculating the standard deviation of hue (H-SD). Assessments were performed at insertion (T Results: No statistically significant differences were observed between conventional and 3D-printed dentures regarding overall OHIP-EDENT scores or individual domains at T Conclusion: Within the limitations of this randomized crossover study, 3D-printed dimethacrylate-based resin complete dentures demonstrated clinical performance and satisfaction comparable to conventional dentures, supporting their use as a reliable alternative in complete denture rehabilitation.
