摘要/Abstract

摘要： ［摘要］目的观察逐步式双牙合垫矫治器治疗青少年下颌后缩畸形前后上气道形态的变化情况。方法使用逐步式双牙合垫矫治器对13例下颌后缩型安氏Ⅱ类Ⅰ分类患者进行矫治,分析比较矫治前后的X线头颅侧位片。结果戴用逐步式双牙合垫矫治器后PNS-Ad2增大，但差异无统计学意义（P＞0.05）。PNS-R，SPP-SPPW，U-MPW，PAS，V-LPW，H-MP，H-C3Me，H-CVP，TGI，TGH，SPL，SPT均显著性增大，差异均有统计学意义（P<0.05）。结论逐步式双牙合垫矫治器能扩大患者上气道,改善患者的通气功能。

Abstract: Abstract: Objective To investigate changes of the upper airway dimensions before and after using stepwise Twinblock appliances （TB appliance）in young adult patients with mandibular retrognathia malocclusion.Methods 13 Angle class II division I patients with mandibular retrusion in mixed dentition or early permanent dentition were treated with stepwise Twinblock appliances.Cephalometric analysis was made before and after treatment.Results After the treatment,PNSR,SPPSPPW,UMPW,PAS,VLPW,HMP,HC3Me,HCVP,TGI,TGH,SPL,SPT increased significantly （P<0.05）,while PNSAd2 increased with no statistical significance （P＞0.05）.Conclusions Stepwise TB appliances can enlarge the patients upper airway and thus effectively improve the airway ventilation in the treatment of mandibular deficiency.
