Three-Dimensional-Printed Splint for Use in Pediatric Mandibular Fracture

Mandibular fractures are the most common type, accounting for about 71% of facial fractures in children. The mandible is the only movable bone in the craniomaxillofacial region. The injury of the mandible has a serious impact on the functions of children's mouth opening, chewing, pronunciation, and occlusion. Therefore, the treatment of children's mandibular fractures is particularly important. Because of the characteristics of children with permanent tooth germ blocking and strong skeletal development, the treatment methods of adults cannot simply be used in children with mandibular fractures. Here, we demonstrate the simple, reliable method using 3-dimensional-printing splint for stability of the fracture segments in pediatric patients.
