Evaluation of the application of three dimensional-printed occlusal splint in conservative treatment of condylar fractures.
Observational study in BMC 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
backgroundConservative treatment of condylar fractures requires the use of occlusal splints. However, limited mouth opening, pain, and tooth damage often prevent timely impression taking, which hinders the fabrication of the occlusal splints. Therefore, there is an urgent need for a convenient and new method. The objective of this study is to evaluate the clinical outcomes and feasibility of innovative 3D-printed occlusal splints for the conservative treatment of condylar fractures.
methodsThis was a retrospective observational case series study aimed to investigate the clinical outcomes of 3D-printed occlusal splints in the conservative treatment of condylar fractures. The patients were divided into pediatric, adolescent, and adult groups according to age. The 3D-printed occlusal splint was secured to the maxilla for 2 months. Patients were instructed to perform mouth-opening exercises daily. Mouth opening was recorded before treatment and at the 3-month follow-up. Data were statistically analyzed.
resultsAfter 3 months of follow-up, no patients reported persistent pain, with mouth-opening and masticatory functions recovered. The postoperative mouth opening of all three groups was significantly greater compared with preoperative values, and the difference was statistically significant (P < 0.05). Regarding deviation of the mandible during mouth opening, the adolescent group showed significant improvement postoperatively (P < 0.05), whereas no statistically significant difference was observed in the pediatric group and the adult group.
conclusionThe use of a 3D-printed occlusal splint combined with mouth-opening exercises is a feasible approach for the conservative treatment of condylar fractures.
