前方牵引联合快速扩弓矫治骨性Ⅲ类错
The Journal of Practical Medicine(2008)
Abstract
目的:评价前方牵引联合快速扩弓矫治替牙期骨性前牙反引起的牙颌面软硬组织变化。方法:对20例7~9.2岁替牙期患者以T2-T1代表自然生长6个月的改变,T3-T2代表应用前方牵引联合快速扩弓6个月的改变,对软硬组织的变化进行分析。结果:治疗6个月后,A点前移1.47mm,SNB、SNPg和Pg-Np明显减小,ANB增大3.62°Wits值增加4.39mm,上唇倾角明显改善。结论:前方牵引联合快速扩弓能促进上颌骨发育,下颌,骨后下移位,有效纠正替牙期前牙反,改善侧貌。
