微种植体支抗辅助正畸治疗推磨牙向远中疗效分析

Effect of Micro Implant Anchorage Assisted Orthodontic Treatment of Molar Distalization

目的:探究微种植体支抗辅助正畸治疗对于推磨牙向远中的治疗效果。方法:选择2017年1月~2018年1月本院正畸科收治的牙齿轻度拥挤患者共计52例。对照组26例采用常规正畸治疗,观察组26例采用微种植体支抗辅助正畸治疗。在治疗结束后对两组患者的治疗效果进行对比。结果:观察组患者的磨牙移位程度、上中切牙倾角差、上中切牙凸距差优于对照组,且观察组治愈率为100%,高于对照组的88%;观察组患者的炎症反应指标治疗后较对照组更低,治疗满意度更高,并发症发生率更低,咀嚼功能和咬合力更高,差异存在统计学意义(P<0.05)。结论:微种植体支抗在推磨牙远移中可以有效地远中移动上颌磨牙,开拓间隙,解除牙列拥挤,达到不拔牙矫治的目的,且在支抗控制方面,更加稳定可靠。

Objective:To explore the effect of Microimplant anchorage assisted orthodontic treatment on distalization of molars.Methods:A total of 52 patients with mild dental crowding in our orthodontic department from January 2017 to January 2018 were selected.26 cases in the control group were treated with conventional orthodontic treatment,and 26 cases in the observation group were treated with micro implant anchorage assisted orthodontic treatment.At the end of the treatment,the treatment effect of the two groups were compared.Results:The degree of molar displacement,upper central incisor angle difference and upper central incisor protrusion difference of the observation group were better than those of the control group,and the cure rate of the observation group was 100%,higher than 88%of the control group;The severe reaction index of the observation group was lower than that of the control group after treatment,the treatment satisfaction was higher,the incidence of complications was lower,the masticatory function and bite force were higher,and the difference was statistically significant(P<0.05).Conclusion:Micro implant anchorage can effectively move the maxillary molars,open up the space,relieve the crowding of dentition,and achieve the purpose of non extraction orthodontic treatment,and it is more stable and reliable in anchorage control.
