目的：应用改良的便利型舌簧和邻间钩活动矫治器取代目前临床常用的双曲舌簧和邻间钩活动矫治器，并与常用的双曲舌簧在弯制、临床应用、外观等方面进行了比较分析．方法：使用常用不锈钢丝弯制改良便利型舌簧和邻间钩，制作活动矫治器治疗牙性前牙反、内倾型深覆、前牙扭转及轻度拥挤．结果：改良舌簧和邻间钩活动矫治器制作简单，加力方便，临床效果良好．结论：改良便利型舌簧，具有夹板样作用，可同时作用于多个前牙，产生按牙弓弧形均匀扩弓的效果，使舌簧的使用范围扩展．如附以导杆或平导可使作用力方向更易控制．改良便利型舌簧和邻间钩没有游离的末端配合应用使整个矫治器固位好，戴用舒适 OBJECTIVE: To replace the commonly used hyperbolic reed and interocular hook active appliances with the modified convenient reed and the adjacent hook active appliance, and to compare with the commonly used hyperbolic reed in bending, clinical application, appearance, etc. Conducted a comparative analysis. Methods: The commonly used stainless steel wire bending system to improve the convenience of reed and the adjacent hook, the production of active appliances for the treatment of anterior teeth inverted anteroposterior pectoralis medulla oblongata, anterior torsion and mild crowding. Results: The modified reed and the adjacent hook activity appliance made simple, easy to add force, the clinical effect is good. CONCLUSION: The improved convenience tongue has the effect of splint-like action and can act on multiple anterior teeth at the same time, resulting in the effect of expanding the arch evenly according to the arc of the arch and expanding the use of the tongue. If attached to the guide rod or guide the force direction can be more easily controlled. Improved Convenience Reed and Adjacent Hooks No Free End-Mating Application Retains Entire Appliance, Comfortable to Wear
