Orthodontic treatment for primary dentition of a child with maxillary complex fracture

Objective To explore the clinical effect of orthodontic treatment for primary dentition of a child with maxillary complex fracture. Methods Five children with maxillary complex fractures were selected. Slight occlusal splint were used intra-orally, and protraction face masks with elastic bands or headgears were used extra-orally within one week after the trauma. Inter-maxillary elastics and extra-oral tractions were performed. Results Normal occlusion and better fractures reduction and fixation were obtained by this means. Conclusion Maxillary complex fractures can be treated with orthodontic appliances effectively, and the soft tissue profile are refined.
