Effect of Microimplant Anchorage in Orthodontic Treatment of Adolescents and Its Effect on Masticatory Function and Bite Force
Objective To investigate the effects of implant anchorage on masticatory function and occlusal force in adolescents.Methods 68 adolescent orthodontic patients admitted to the author's hospital from January 2018 to January 2021 were included in the study.They were randomly divided into control group and observation group with 34 cases each.The patients in the control group were treated with traditional orthodontic extraoral arch anchorage,and the patients in the observation group were treated with implant anchorage nails.The treatment period of the two groups was 18 months.The therapeutic effect,orthodontic effect(molar displacement,upper central incisor Angle difference and upper central incisor Angle difference between the two groups),masticatory efficiency and biting force of the two groups were compared,and the satisfaction of the two groups was evaluated by self-designed satisfaction questionnaire.Results The effective rate of observation group was higher than the control group(P＜0.05).The distance of molar displacement in the observation group was less than that in the control group,while the difference of convexity and inclination angle of upper central incisors in the observation group was greater than that in the control group(P＜0.05).After treatment,the masticatory efficiency and occlusal force of the two groups were improved,and the observation group was higher than the control group(P＜0.05).The scores of appearance,comfort,occlusal function and convenience in the observation group were higher than those in the control group(P＜0.05).Conclusion Adolescent orthodontic treatment with implant anchorage nail orthodontic effect is significant,can effectively improve the masticatory function,increase occlusal cases,patient satisfaction is high.
