Abstract: Objective: To explore the effect of micro-implant nail combined with self-efficacy intervention on the profile, facial shape and psychological status of adolescents with orthodontic treatment. Methods: From April 2016 to November 2018, 90 patients with gingiva in orthodontic Department of our hospital were recruited and randomly divided into three groups, 30 in each group. The routine group was treated with high J hook traction, the micro-needle group was treated with micro-implant nail, and the combined group was treated with self-efficacy intervention. The gingival exposure, profile, facial type and psychological status of the three groups were compared.Result: There was no significant difference in gingival exposure among the three groups before treatment (P > 0.05). After 2, 3 and 4 months of treatment, the gingival exposure in the microneedle group and the combined group was lower than that in the conventional group (P< 0.01), and the combined group had better effect (P< 0.01). After 4 months of treatment, the changes of side appearance and facial shape indexes in the micro-needle group and the combined group were better than those in the conventional group (P < 0.01), but there was no difference between the micro-needle group and the combined group (P > 0.05). There was no significant difference in SAS and SDS scores before and after treatment in the conventional group (P > 0.05). Compared with before treatment, SAS and SDS scores in the micro-needle group and the combined group were significantly lower after treatment (P < 0.01), and the combined group was better than the micro-needle group (P < 0.01). Compared with the conventional group, the satisfaction of micro-needle group and combined group was significantly improved (P > 0.01), the satisfaction of combined group was 93.3%, and that of micro-needle group was 70.0%. The difference between the two groups was significant (P > 0.01). Conclusion: Microimplant nail combined with self-efficacy intervention can significantly improve gingival exposure in patients with orthodontic treatment. It also has certain effect on patients'profile and facial shape, and can effectively alleviate negative emotions in the treatment process.
