Abstract：Objective: To analyze the effect of micro-implant anchorage on the efficacy and compliance of orthodontics.Method: 180 patients with orthodontic treatment in our hospital from January 2017 to January 2019 were selected as the research objects and randomly divided into observation group and control group,with 90 cases in each group.The observation group was treated with micro implant anchorage,while the control group was treated with non-implant anchorage.The model,oral health related quality of life (OHRQoL) scale score,adverse reactions and patient compliance were compared between the two groups before and after treatment.Results: Compared with the model overbite,model coverage,canine width and first molar width of the two groups,the improvement degree of the observation group was more significant (P<0.05).The changes of upper alveolar angle,upper and lower alveolar seat angle,Sn angle of upper central incisor and upper lower central incisor angle of the two groups were compared.The changes of each index in the observation group were more significant than those in the control group (P<0.05).In this paper,t-test was used to compare the scores of OHRQoL scale between the two groups from the aspects of physiological pain,functional limitation,physiological dysfunction,social ability limitation,psychological disorder,limb movement disability and inner communication ability.The results showed that the score of the observation group was significantly higher than that of the control group (P<0.05).At the same time,the difference in the incidence of adverse reactions before and after treatment was compared by means of chi square test.The results showed that the observation group was significantly lower than the control group (χ2= 4.367,P<0.05).Finally,the difference of excellent and good compliance rate between the two groups was compared by using the method of chi square test.The results showed that the observation group was significantly higher than the control group (χ2= 5.262,P<0.05).Conclusion: The orthodontic effect of micro-implant anchorage is better,which can improve oral health and reduce the incidence of adverse reactions,and the patients are more acceptable.
