Objective： To investigate the clinical effect of early functional correction of muscle function in children with orthodontics. Methods： The clinical data of 127 children with orthodontic treatment in our hospital from January 2008 to December 2016 were divided into study group （ n =67） and control group （ n =60） according to different treatment methods. In the control group, no early muscle function training and correction techniques were used to study the early stage muscle function correction in the group, and the clinical efficacy was compared between the two groups. Results： The study group had significantly longer correction time （16.34？.46） d, orthodontic teeth correction time （16.24？.43） days and complete treatment time （39.42？.78） days than control group （ P 〈 0.05）. Conclusion： The application of muscle functional correction in the early stage of orthodontic treatment can effectively correct the malocular deformity in children, and the family members of the children are satisfied with the aesthetic appearance of the maxillofacial region.
