    摘要:

    目的:分析头帽Twin-block矫治器对骨性Ⅱ类1分类患者的颌骨生长以及软组织侧貌的影响。方法:36例安氏Ⅱ类1分类错牙合畸形患者平均分为3组,每组12例;第1组(R组)使用头帽Twin-block矫治器治疗;第2组(T组)使用传统Twin-block矫治器治疗;第3组(C组)为对照组,选择同样条件的初诊检查后未治疗者。3组纳入标准相同:上齿槽座点-鼻根点-下齿槽座点角(ANB)≥4.5°,前牙覆盖≥6 mm,覆牙合≥3 mm,下颌后缩。分别于治疗前后或观察前后拍摄头颅侧位X片并进行头影测量分析。结果:与T组相比,R组蝶鞍点-鼻根点-上齿槽座点角(SNA)-上中切牙-前颅底平面角(U1-SN)-上唇审美平面距(Ls-E)-下唇审美平面距(Li-E)-上切牙露齿度(U1-Stms)-上颌6到FHp距离(U6-FHp)的减少量-驻R更大,有统计学差异(P < 0.05);上颌6到CFH距离(U6-CFH)-下颌平面角(SN-MP)-上颌平面角(PP-SN)的增加量更少,有统计学差异(P < 0.05)。结论:头帽Twin-block矫治器能促进下颌骨生长,同时能够有效抑制上颌骨发育,矫治生长发育期骨性Ⅱ类错牙合,改善上下颌骨关系,改善患者面型。

    Abstract:

    Objective:To evaluate the effects produced by Headgear-Twin-block appliance for skeletal Class Ⅱ malocclusion. Method:One treatment group(Group R)consisted of 12 patients(8 males,4 females,mean age of 11 years 2 months)who treated with Headgear-Twin-block appliance.The other treatment group(Group T)also consisted of 12 patients(8 males,4 females,mean age of 11 years 6 months)who treated with Twin-block appliance without headgear. The control group(Group C)contained 12 patients(6 males,6 females,mean age of 10 years 8 months)giving up treatment after the examination. All the patients met the criteria as follows:(1)ANB≥4.5°;(2)Overjet≥6 mm and overbite≥3 mm;(3)Retrusive mandible. The patients of three groups were taken cephalometrics before and after the treatment or observation. Results:Compared -驻R with -驻T,SNA,U1-SN,Ls-E,Li-E,U1-Stms,U6-FHp decreased more and PP-SN,SN-MP,U6-CFH increased less,which had significantly difference (P < 0.05). Conclusion:Headgear-Twin-block appliance is effective to treat Class Ⅱ division 1 malocclusion by promoting the mandible and restraining the maxillary effectively to improve hard and soft tissue.
