The effect, safety and compliance of micro-implant anchorage in adolescent orthodontic treatment

Abstract

Objective To investigate the effect, safety and compliance of micro-implant anchorage in adolescent orthodontic treatment. Methods A total of 50 adolescent patients who underwent orthodontic treatment from March 2017 to March 2019 in the Department of Stomatology, Li Huili Hospital of Ningbo Medical Center were selected and randomly divided into control group and observation group according to the digital table, with 25 cases in each group.The control group received conventional corrective treatment, and the observation group received micro-implant anchorage therapy.The treatment efficacy, upper incisor dip angle and tooth convexity difference, molar displacement, safety, adverse reactions and compliance were compared between the two groups. Results There were no statistically significant differences in gender, age, etc.between the two groups(all P>0.05). The improvement of the incisor angle difference, tooth crown distance difference and molar displacement difference in the observation group were significantly better than those in the control group, the differences were statistically significant(t=11.328, 20.011, 17.336, all P<0.05). The incidence of adverse reactions such as soft tissue edema, oral inflammation and discomfort of correction in the observation group (8%) was lower than that in the control group(28%), the difference was statistically significant(χ2=10.225, P<0.05). The compliance of patients in the observation group (96%) was significantly higher than that in the control group (80%), the difference was statistically significant(χ2=19.316, P<0.05). Conclusion The micro-implant anchorage is effective in the clinical treatment of adolescent orthodontics, with high safety and high patients’ compliance.It is worthy of clinical promotion.
