The application of 3D digitization technology and 3D printing in the treatment of mandibular fractures in pediatric population.
Article 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
objectiveTo explore the clinical value of three-dimensional digital technology and 3D-printed surgical guides in the treatment of pediatric mandibular fractures with transitional dentition. At the same time, focus on the fixed dentition defects in children, jawbone development, and the protection of permanent tooth germs.
methodsThis case series reviewed three pediatric patients with mandibular fractures in the mixed dentition period, presenting with varying injury severity. For each case, CT data were utilized to create three-dimensional digital models of the jawbone, deciduous dentition, and tooth buds. A virtual reduction was performed to restore the occlusal relationship, followed by the digital design of patient-specific occlusal splints. Both the splints and the corrected jaw models were then 3D-printed and used intraoperatively to guide precise reduction and fixation. Postoperative outcomes were assessed through clinical follow-up, and the results were contextualized with a review of the relevant literature.
resultsPostoperative follow-up showed good healing of the mandibular fracture, with no impact on mandibular development and the tooth germs are undamaged. The postoperative occlusal relationship was satisfactory.
conclusionThe use of computer-aided three-dimensional digital technology and 3D printing technology, based on CT data for occlusal reconstruction, assists in the accurate reduction of mandibular fractures and minimizes the impact on mandibular development and tooth germ eruption. The demonstrated workflow establishes a valuable and reliable technique for the treatment of mandibular fractures in children, offering a significant advantage in preserving long-term function and growth.
