无托槽隐形矫治器治疗前磨牙轻中度扭转的临床分析

Clinical Analysis of Invisible Appliance Without Bracket in the Treatment of Mild to Moderate Anterior Molar Torsion

目的分析无托槽隐形矫治器治疗前磨牙轻中度扭转的效果。方法选取2018年1月—2019年1月于本院治疗的前磨牙扭转患者100例为研究对象,随机分为对照组(采用传统固定矫治器治疗)以及观察组(无托槽隐形矫治器治疗)。对比两组患者治疗效果与相关指标。结果与对照组相比,观察组的治疗有效率更高,美观舒适度,便捷程度,语言功能以及咀嚼功能评分更高,转位牙扶正时间高于对照组所用时间,两组对比有统计学意义(P<0.05)。结论采用无托槽隐形矫治器对前磨牙轻中度扭转有理想的矫正效果,在美观,咀嚼等方面具有特殊优势,值得推广。

Objective To analyze the effect of bracketless invisible appliance on the treatment of premolar torsion.Methods 100 cases of premolar torsion treated in our hospital from January 2018 to January 2019 were randomly divided into control group(treated with traditional fixed appliance)and observation group(treated with bracketless invisible appliance).The therapeutic effect and related indexes were compared between the two groups.Results Compared with the control group,the effective rate,aesthetic comfort,convenience,language function and masticatory function score were higher in the observation group,and the time of transposition tooth correction in the observation group was higher than that in the control group,and the comparison between the two groups was statistically significant(P<0.05).Conclusion The use of the bracketless invisible appliance has an ideal effect on the mild to moderate torsion of premolars,and has special advantages in beauty,chewing and so on.
