Application of fully digital occlusal splints in painful temporomandibular disorders: a randomized controlled clinical study.
Trial report in Head & face medicine, 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
objectiveTo evaluate the clinical efficacy of digital occlusal splints in alleviating pain and dysfunction in patients with temporomandibular disorders (TMD) and underlying mechanisms.
methodsTMD patients were enrolled and divided into digital and conventional occlusal splint groups (n = 66/group). Clinical outcomes, including visual analog scale (VAS) scores and temporomandibular function indices [Craniomandibular Index (CMI), Dysfunction Index (DI), Palpation Index (PI)], were assessed pre- and post-treatment. Cone-beam computed tomography (CBCT) was used to analyze condylar positional changes and joint space adaptation, while quantitative polymerase chain reaction and enzyme-linked immunosorbent assay measured serum levels of inflammatory markers. Correlations between clinical, structural, and biochemical parameters were examined.
resultsBoth groups exhibited significant post-treatment reductions in VAS scores, CMI, DI, and PI (P < 0.05), with the digital group demonstrating superior improvements in VAS, PI, and CMI compared to controls (P < 0.001). CBCT revealed favorable structural adaptations in both groups, though the digital group showed greater enhancements in glenoid fossa depth and medial joint space (P < 0.05). Biochemical analysis confirmed significant decreases in tumor necrosis factor-α (TNF-α), fibroblast growth factor receptor 3 (FGFR3), and nitric oxide synthase 2 (NOS2) levels, with additional reductions in nerve growth factor (NGF) and human leukocyte antigen B (HLA-B) observed exclusively in the digital group (P < 0.05).
conclusionDigital occlusal splints effectively mitigate TMD-related pain and dysfunction, likely through synergistic mechanisms involving occlusal stabilization, joint structural optimization, and inflammatory modulation. This technology represents a promising precision-based approach for personalized TMD management.
