摘要
目的:探讨头帽肌激动器联合应用对生长期安氏II1类骨性错牙合的牙、颌、颅面的影响。方法:选择11例早期安氏II1类骨性错牙合采用头帽肌激动器联合矫治的患者,对其治疗前后的X线头影测量分析比较。结果:11例患者经过6～8个月的治疗,抑制上颌骨发育,促进下颌骨生长效果显著。ANB角、U1-NB距、U1-NA距、wits值、覆牙合、覆盖减小,SNB角、U1-L1角、Po-NB距显著增加(P<0.05),上下颌间关系协调。磨牙关系为I类或偏Ⅲ类关系。结论:头帽牵引和肌激动器联合矫治适用于骨性安氏II1错牙合的早期矫治,可快速有效地改善患者的侧面型。
Objective To investigate the clinical effect of Headgear-activator in the treatment of skeletal class Ⅱ division 1 malocclusion. Methods 11 growth patients with skeletal class Ⅱ division 1 malocclusion were treated with Headgear-activator. Pre- and post-treatment cephalograms were compared. Results After a treatment period of 6-8 months, the growth of the mandible was stimulated while the development of the maxilla was inhibited. ANB, OJ decreased significantly while SNB increased significantly. The sagittal disharmony of Angle＇s class Ⅱ malocclusion was corrected. Class Ⅰ or slight class Ⅲ molar relationship was obtained. Conclusion Headgearactivator is fit for the early orthodontic treatment of skeletal class Ⅱ division 1 malocclusion. Headgear-activator is effective to improve the profile of the patients with skeletal class Ⅱ division 1 malocclusion.
