Clinical evaluation of 3D printed splint in the treatment of temporomandibular disorders.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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 use a T-scan (Tekscan, Boston, USA) to evaluate the grinding effect of a three-dimensional (3D) printed occlusal splint and provide reference guidelines for adjusting occlusion and alleviating temporomandibular joint symptoms before orthodontic treatment.
methodsEighteen patients with temporomandibular disorder (TMD) were treated with 3D-printed stable occlusal plates for three months. The occlusal time (OT) of the dentition and the difference percentage of occlusal force between the left and right sides (Asymmetry index of occlusal force, AOF) were observed one week, one, two, and three months after T-scan-guided occlusal splint treatment. Before and after treatment, we investigated joint space, electromyography (EMG), the maxillofacial pain visual analog scale (VAS), and the Chinese version of the jaw function limitation scale (JFLS).
resultsSignificant reductions in OT and AOF were observed across four time points in TMD patients wearing T-scan-guided occlusal splints (P < 0.05). Furthermore, the bilateral masseter muscle (MM) and temporalis anterior (TA) asymmetry index were reduced at the mandibular postural and intercuspal positions. Cone beam computed tomography (CBCT) showed that the anterior space of the articular had decreased, the posterior space had increased, and the VAS and JFLS scores had decreased significantly (P < 0.05).
conclusionT-scan accurately located the abnormal occlusal contact point, guidance enhances occlusal equilibration and may improve TMJ function and symptoms in TMD patients.
