Abstract
Objective:To investigate the changes in soft and hard tissues of patients with Angle's Class Ⅱ1 malocclu-sion and deep overbite treated with fixed orthodontic technique combined with micro-implant anchorage.Methods:A total of 34 patients with Angle's Class Ⅱ1 malocclusion and deep overbite who underwent orthodontic treatment in the hospital from June 2022 to March 2024 were selected as the study subjects.They were divided into two groups using a table of random numbers,with 17 cases in each group.The control group was treated with fixed orthodontic appliance and headgear anchorage while the observation group received orthodontic treatment with fixed orthodontic technique and micro-implant anchorage.The changes in soft and hard tissues before and after treatment,as well as the occlusal function and masticatory function before and after 3 months of treatment,and the incidence of complications were compared between the two groups.Results:After treatment,there was no statistically significant difference in SNA,SNB,or ANB between the groups(P>0.05).U1-NA angle,U1-NA distance,Overjet and Overbit in the observation group were smaller than those in the control group.The nasolabial an-gle and the thickness of soft-tissue chin were greater than those in the control group(P<0.05).After treatment,bite force and masticatory efficiency of the observation group were higher than those of the control group(P<0.05).The incidence of com-plications in the observation group(11.76%)was lower than that in the control group(29.41%),but the difference was not statistically significant(P>0.05).Conclusion:Applying fixed orthodontic technique combined with micro-implant anchorage in orthodontic treatment of patients with Angle's Class Ⅱ1 malocclusion and deep overbite can improve the morphology of soft and hard tissues,and enhance their occlusal function and masticatory function,with satisfactory clinical effects.关键词
