口腔正畸过程中,摇椅形弓丝常用于解决深覆牙合的问题,通过压低前牙,伸长后牙打开咬合。有的医师认为镍钛丝摇椅弓效果不明显,提倡应用不锈钢丝摇椅弓[1]。本实验探讨不同Spee曲线深度的情况下,不同尺寸及深度的不锈钢摇椅形弓丝对双尖牙区应力大小的影响。1材料与方法 1.1模型的建立:在Typodont模型牙上(日本TOMY公司)粘接OPA-K直丝弓托槽(日本TOMY公司),选取排齐
Orthodontics, rocker-shaped arch wire is often used to solve the problem of deep overbite, open the bite by extending the anterior teeth and extending the posterior teeth. Some doctors believe that nickel titanium rocking chair bow effect is not obvious, to promote the use of stainless steel wire rocker bow [1]. This experiment explored the different Spee curve depth cases, different sizes and depths of stainless steel rocker-shaped arch wire on the canine stress effects. 1 Materials and methods 1.1 The establishment of the model: On the model of the teeth of Typodont (Japan TOMY Corporation) OPA-K straight wire brackets (Japan TOMY Corporation), select the alignment
