Objective: To analyze the effects of occlusal induction combined with muscle function training on jawbone development and masticatory efficiency in children with type II malocclusion of An"s. Methods: 112 children with type II dislocation malformations of Ann"s who visited our hospital from February 2022 to December 2023 were selected as the research subjects. The patients were divided into the control group and the study group according to the random number method, with 56 cases in each group. The control group received corrective treatment using occlusion-induced orthodontic appliances. The research group adopted occlusion-induced orthodontics combined with muscle function training. The jawbone development [superior alveolar seat Angle (SNA), inferior alveolar seat Angle (SNB), ANB Angle, mandibular plane Angle (MP-FH), face Angle (FH-NPo); superior central incisor inclination (U1-SN), superior central incisor protrusion (U1-NA), inferior central incisor inclination (IMPA), inferior central incisor protrusion (FMIA); Overall high (N-Me), upper high (N-ANS), lower high (ANS-Me) Coverage, overbite], masticatory efficiency and muscle function [electromyographic activities of the anteriortemporal muscles (TA) and masseter muscles (MM) on the affected side at rest and in the maximum occlusal state]of the two groups were analyzed and compared. Results: After 12 months of correction, there were no significant differences in the angles of SNA, SNB, ANB, MP-FH, FH-NPo, U1-NA and N-ANS between the two groups (P > 0.05); However, the U1-SN, N-Me, ANS-Me, IMPA, FMIA, coverage and overbite Angle of the study group after 12 months of correction were significantly higher than those of the control group (P<0.05). After 12 months of correction, the chewing efficiency of both groups was significantly increased compared with that before correction (P < 0.05), and the chewing efficiency of the study group after correction was significantly higher than that of the control group (P < 0.05). After 12 months of correction, the electromyography of TA and MM in the resting state in both groups was significantly lower than that before correction, and the electromyography of TA and MM in the maximum occlusal state was significantly higher than that before correction. Moreover, the improvement amplitudes of TA and MM electromyography in the resting state and the maximum occlusal state in the study group were significantly greater than those in the control group (P<0.05). Conclusion: Occlusal induction combined with muscle function training can promote the development of the jawbone in children with type II Amnestic malocclusion, improve chewing efficiency and enhance muscle function.
