摘 要:目的分析传动直丝弓矫治器治疗安氏Ⅲ类错颌前后的软硬组织变化。方法选取安氏Ⅲ类错颌非拔牙患者10例,使用传动直丝弓技术进行矫治,通过对比治疗前后头影测量分析得出软硬组织变化。结果治疗后软组织UL-EP、UL-Sn-Pogs增大,Z角、LL-EP、LL-Sn-Pogs减小;骨组织指标∠ANB、Wits值、∠NA-PA增大,∠NP-FH减小;牙性指标中∠U1-SN、∠U1-NA、U1-NA距增大,∠U1-L1减小,以上指标通过t检验显示差异具有统计学意义(P<0.05)。结论传动直丝弓矫治器能够有效矫治安氏Ⅲ类错颌,治疗前后患者的软硬组织得到明显改善。Objective To analyze changes of hard and soft tissues in adult patients who were Class III malocclusion by transmission straight wire appliance.Methods Using transmission standard straight wire appliance to treat 10 adult patients with Class III malocclusion and comparing hard and soft tissues’changes of pre-treatment and post-treatment analyzed by lateral head films.Results About soft tissues,ULEP and UL-Sn-Pogs are higher,LL-EP、LL-Sn-Pogs and Z angle are smaller;for bone,ANB angle、Wits value and NA-PA angle increase,NP-FH angle decrease;for teeth,U1-SN angle、U1-NA、the distance of U1-NA increase,U1-L1 angle decrease.By t-test,the above indicators were statistically significant(P<0.05).Conclusion Using transmission straight wire correction technique for adult patients with Class III malocclusion without extraction,the side face and the relationship of hard tissues of patients were improved after treatment.
