摘　　要：目的:探究无托槽隐形矫治器拔牙治疗双牙弓前突的临床疗效。方法:选取2018年1月~2019年12月本院收治的12例双牙弓前突患者,在拔除4颗第一前磨牙后结合强支抗并采用无托槽隐形矫治器治疗双牙弓前突。应用头颅侧位X射线摄片对患者治疗前后的相关数据进行对比。结果:通过治疗后患者的SNA、SNB、ANB、U1NA、L1NB距离、L1MP、L1NB角、上下唇线到E线的距离及鼻唇角测量数据皆与治疗前有较大差异,P<0.05,具有统计学意义,而ANB、FMA角,FHNP、NAAP、Pog-NB和Y轴均无明显差异,P>0.05,无统计学意义。结论:托槽隐形正畸治疗作为一种快速发展的新型正畸技术,以其可拆卸、美观、舒适、方便、可预测性强等优点受到广大患者和正畸医师的青睐。无托槽隐形矫治器在拔除第一前磨牙并结合强支抗对治疗牙弓前突临床效果较好,可有效改善双牙弓前突患者的侧貌,较传统矫治方式相比,在促进患者口腔卫生的保持、咬合的稳定性方面均有较大优势。Objective:To explore the clinical effect of tooth extraction invisible appliance without brackets in the treatment of double dental arch protrusion.Methods:A total of 12 patients with orthodontic anterior arch were selected from our hospital from January 2018 to December 2019.After the extraction of 4 first premolars,combined with strong anchorage,the orthodontic anterior arch was treated with a bracket less appliance.Lateral cranial X-ray was used to compare the relevant data before and after treatment.Results:After treatment,SNA,SNB,ANB,U1NA,L1NB distance,L1MP,L1NB Angle,upper and lower lip line to E line and nasolabial Angle were significantly different from those before treatment,P<0.05 was statistically significant,while ANB,FMA Angle,FHNP,NAAP,POG-NB and Y axis were not significantly different,P>0.05 was not statistically significant.Conclusion:As a new orthodontic technology with rapid development,bracket invisible orthodontic treatment is favored by the majority of patients and orthodontists for its advantages of disassembly,beauty,comfort,convenience and predictability.It can effectively improve the profile of patients with double arch protrusion.Compared with traditional orthodontic treatment,it has greater advantages in promoting the maintenance of oral health and the stability of occlusion.
