摘　　要：目的通过比较改良型FRⅢ与“2×4”矫治技术治疗替牙期前牙反牙合患者的软硬组织变化,评价两种矫治方法的治疗效果,为临床选择应用提供理论参考。方法选择2018年9月—2022年10月在本院口腔科门诊治疗的替牙期前牙反牙合患者30例作为研究对象,根据治疗方法不同分为观察组(改良型FRⅢ)和对照组(“2×4”矫治技术)两组,每组各15例。对两组病例矫治前后的软硬组织位置变化进行对比分析。结果治疗完成后,观察组SNA、ANB、MP-FH、Y轴角、U1-SN、U1-NA、鼻唇角、颏唇角、面型角、上唇E线距、ULP增加(P<0.05),SNB、Z角、NP-FH、L1-MP、U1-L1、下唇E线距减小(P<0.05);对照组SNA、ANB、MP-FH、U1-SN、U1-NA、Y轴角、鼻唇角、面型角、上唇E线距增加(P<0.05),SNB、NP-FH、U1-L1、下唇E线距、Z角减小(P<0.05);两组之间,SNB、ANB、MP-FH、鼻唇角、颏唇角、面型角及Z角的变化量比较具有明显差异(P<0.05)。结论两种技术治疗均取得良好的治疗效果,前牙反牙合得到有效解除,咬合关系及面型恢复正常,具有临床应用价值,值得推广。改良型FRⅢ更好地改善软组织侧貌和面型,而“2×4”矫治技术用时更短,牙列关系得到更好的解决。Objective To evaluate the therapeutic effects of two orthodontic methods by comparing the soft and hard tissue changes of patients with anterior crossbite in mixed dentition treated with the modified FRIII and“2×4”orthodontic techniques,and to provide theoretical references for clinical selection and application.Methods From September 2018 to October 2022,30 patients with anterior crossbite in mixed dentition those were treated in the outpatient clinic of stomatology department in the second affiliated hospital of north Sichuan Medical College were collected as study subjects,and they were divided into an observation group(modified FRIII,n=15)and a control group(“2×4”orthodontic technique,n=15)according to the treatment method.The changes in the position of the hard and soft tissues in the two groups were compared before and after orthodontic treatment.Results After treatment,the SNA,ANB,MP-FH,Y-axis angle,U1-SN,U1-NA,nasolabial angle,chin-labial angle,facial angle,upper lip E line distance and ULP increased in the observation group(P<0.05)and the SNB,Z angle,NP-FH,L1-MP,U1-L1 and lower lip E line distance decreased in the control group(P<0.05).The SNA,ANB,MP-FH,U1-SN,U1-L1,Y-axis angle,nasolabial angle,facial angle,and lower lip E line distance decreased in the control group(P<0.05).While SNB,NP-FH,U1-L1,lower lip E line distance,and Z angle decreased in the control group(P<0.05).The amount of changes in SNB,ANB,MP-FH,nasolabial angle,chin-labial angle,facial angle,and Z angle were significantly different between the two groups(P<0.05).Conclusions Both techniques achieved good treatment results,anterior teeth were effectively released,and the occlusal relationship and facial shape were restored to normal,which is worth promoting for clinical application.The modified FRIII improved the lateral appearance and facial shape of the soft tissues better,while the“2×4”orthodontic technique took less time and provided a better resolution of the tooth alignment.
