摘要
目的探讨标准方丝弓矫治器矫治安氏Ⅱ类Ⅰ分类错[牙合]的软组织侧貌变化。方法选取2017年4月~2020年3月抚顺市口腔医院收治的74例安氏Ⅱ类Ⅰ分类错[牙合]患儿作为研究对象,根据抽签法分为研究组(37例)与对照组(37例)。研究组采用标准方丝弓矫治器联合传统Twin-Block矫治器治疗,对照组采用传统Twin-Block矫治器治疗。比较两组的H角、软组织颊面角、上唇凸距、下唇凸距、正畸(PAR)总分。结果矫治后研究组H角、软组织颊面角、上唇凸距、下唇凸距小于对照组,差异有统计学意义(P<0.05)。研究组PAR总分低于对照组,差异有统计学意义(P<0.05)。结论标准方丝弓矫治器联合传统Twin-Block矫治器有助于提高安氏Ⅱ类Ⅰ分类错[牙合]患儿的正畸质量,改善其软组织侧貌。
Objective To explore the analysis of the soft tissue profile changes in the treatment of Angle′s classⅡdivisionⅠmalocclusion with standard square wire appliance.Methods A total of 74 children with Angle′sⅡdivisionⅠmalocclusion admitted to Fushun Stomatological Hospital from April 2017 to March 2020 were selected as the research objects.They were divided into the study group(37 cases)and the control group(37 cases)according to lotting method.The study group was treated with a standard square wire arch appliance combined with a traditional Twin-Block appliance,while the control group was treated with a traditional Twin-Block appliance.The total scores of H angle,soft tissue buccal angle,upper lip convex distance,lower lip convex distance,and orthodontic(PAR)scores were compared between the two groups.Results The H angle,soft tissue buccal angle,upper lip convexity,and lower lip convexity of the study group were smaller than those of the control group,and the differences were statistically significant(P<0.05).The PAR score of the study group was lower than that of the control group,and the difference was statistically significant(P<0.05).Conclusion The standard square wire arch appliance combined with the traditional Twin-Block appliance can improve the quality of orthodontics and improve the soft tissue profile of children with Angle′s ClassⅡdivisionⅠmalocclusion.
