Objective To observe the efficacy differences between fixed orthodontics treatment and maxillary pad-type removable appliance with double-curved lingual spring in the treatment of early anterior crossbite in children. Methods A total of 60 children with early anterior crossbite admitted to Hefei Stomatological Hospital from January 2020 to December 2022 were selected, and they were divided into the reference group and the observation group by the random number table method, with 30 children in each group. The reference group was treated with maxillary pad-type removable appliance with double-curved lingual spring, and the observation group was treated with fixed orthodontics treatment. The clinical efficacy and cephalometric measurement improvement were compared between the two groups. Results The total effective rate of the observation group (96.67%) was higher than that of the reference group (73.33%) (P <0.05). After treatment, the values of SNA, SNB, ANB, U1-NA, L1-NB and MPA in the observation group were better than those in the reference group (P <0.05). Conclusion Fixed orthodontics treatment shows better efficacy in the management of early anterior crossbite in children, which can effectively improve various cephalometric measurements and is worthy of clinical application.
