Clinical Performance of High-Impact 3D-Printed Denture Resins: A Multicenter Cohort With Survival Analysis.
Article in Cureus, 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 The clinical performance of 3D-printed denture base resins remains incompletely defined under real-world conditions, where workflow variability may influence outcomes beyond material properties alone. Objective This study aimed to compare the clinical performance of Lucitone Digital Print (LDP) (Dentsply Sirona, Charlotte, NC, USA) and SprintRay High Impact (SRHI) (SprintRay, Los Angeles, CA, USA) 3D-printed dentures in a multicenter cohort. The primary objective was to evaluate functional retention in vivo. Secondary objectives included comparison of fracture-free survival, fracture incidence, time to fracture, failure etiology, and assessment of workflow-related factors that may influence clinical outcomes independent of material properties. Methods A cohort of 1,011 dentures (510 LDP, 501 SRHI) was followed through December 31, 2025. Functional retention in vivo was the primary endpoint. Kaplan-Meier survival analysis, log-rank testing, and Cox proportional hazards modeling were performed. Secondary outcomes included fracture-free survival, cumulative breakage rates, time to fracture, and root cause analysis. Results At the final follow-up, 68.0% of LDP and 52.3% of SRHI units remained in vivo. SRHI demonstrated significantly greater functional discontinuation (HR: 1.79; 95% CI: 1.47-2.18; P<.001). Fracture rates were similar between groups (13.3% vs 12.6%), and fracture-free survival did not differ significantly (P=.340). Failures were predominantly associated with prosthesis design and workflow variables. Conclusion Clinical outcomes of 3D-printed dentures are driven more by workflow execution and prosthesis design than by material selection alone.
