| 摘 要： | 目的研究早期应用FR-Ⅰ治疗安氏Ⅱ1前后牙颌面软硬组织的变化并探讨相互关系.方法对10例应用FR-Ⅰ治疗前后的9～11岁安氏Ⅱ1病例X线头颅侧位定位片进行分析,共测量18项硬组织和15项软组织项目,分析治疗前后软硬组织的变化.结果矫治后的硬组织改变主要为SNB角的增大和ANB角的减小,提示下颌骨的生长,面角增加和颌突角减小,上前牙轻度内收和下前牙少量唇倾.软组织面凸角减小,软组织面角和Z角增加,反映软组织侧貌突度减小.结论对安氏Ⅱ1病例早期应用FR-Ⅰ能够产生下颌骨骨骼改变,并达到相应的软组织侧貌的改善.

| Abstract: | Objective To investigate the soft and hard tissue changes of Angle ClassⅡdivision 1 patients after treated by FR-I appliance. Methods Ten ClassⅡdivision 1 cases aged 9～11years were included in the study.Cephalometrics analysis was performed before and after treatment.18 hard tissue and 15 soft tissue measurements were included in the analysis.Results After treatment with FR-I, the mean values of SNA,NP-FH,FH-Ns-Pg',S-N'-B',FH-LL,UL-LL,Z angles and lower lip thickness increased significantly; while that of ANB,NA-PA,Ns-Sn-Pos angles and OJ decreased significantly.Upper incisors retroclined and lower incisors proclined slightly.Conclusion FR-I appliacne can effectively induce forward movement of mandible and improved esthetics on soft tissue profile. |
