摘要
目的:分析双弓丝与主弓丝牵引矫治上颌中切牙埋伏阻生的临床效果。方法:选取2018年7月—2020年7月苏州口腔医院收治的40例上颌中切牙埋伏阻生患者作为研究对象,采用随机数字表法分为两组,各20例。研究组使用双弓丝进行正畸牵引,对照组使用主弓丝进行正畸牵引。比较两组矫治效果。结果:两组总有效率、治疗时间比较,差异无统计学意义(P>0.05)。矫治后,两组SNA角、SNB角、ANB角、MP-FH、L1-MP角、U1-NA角、L1-NB角比较,差异无统计学意义(P>0.05);研究组U1-SN角小于对照组,差异有统计学意义(P=0.04)。结论:双弓丝与主弓丝牵引矫治上颌中切牙埋伏阻生都能够达到预期,双弓丝与主弓丝相比,更有利于切牙唇倾度的控制,在临床工作中可以根据患者具体情况选择合适的方法。
Objective:To analyze the clinical effect of double arch wire and main arch wire for traction of impacted maxillary central incisors.Methods:A total of 40 patients with impacted maxillary central incisors admitted to Suzhou Stomatological Hospital from July 2018 to July 2020 were selected as the study subjects.They were divided into two groups according to random number table method,with 20 cases in each group.The study group used double arch wire for orthodontic traction,and the control group used main arch wire method for orthodontic traction.The orthodontic treatment effect of the two groups was compared.Results:There was no significant difference in total effective rate and treatment time between the two groups(P>0.05).After orthodontic treatment,there was no significant difference in SNA angle,SNB angle,ANB angle,MP-FH,L1-MP angle,U1-NA angle and L1-NB angle between the two groups(P>0.05).The U1-SN angle in the study group was lower than that in the control group,and the difference was statistically significant(P=0.04).Conclusion:Both double arch wire and main arch wire for traction of impacted maxillary central incisors can achieve the expected results.Compared with the main arch wire,the double arch wire is more conducive to controlling the inclination of the incisor lip.In clinical work,suitable methods can be selected based on specific circumstances of patients.
