摘　　要：目的设计一种用于错畸形的正畸治疗的新型托槽——尖牙控轴直丝托槽,对其结构设计和应用原理进行探讨分析。方法定性设计矫治器的结构,托槽两个对角旋转翼与另两个对角翼可以通过旋转轴发生转动,能灵活选择放入弓丝前不锈钢丝结扎托槽与放入弓丝后弹性结扎托槽等结扎方式。结果设计出一种尖牙正畸控轴直丝托槽,其特征是两对角托槽翼与另两个对角翼可以通过旋转轴发生转动,从而改变托槽槽沟的高度及宽度。结论使用尖牙控轴托槽时,可以通过结扎尖牙控轴托槽的合龈翼来选择采取不同的矫治系统。Objective To design a new type of bracket： canine axis adjustable straight wire bracket, which is used to treat malocclusion, and analyse its structure and principle in this article. Methods The structure of axis adjustable bracket is consist of two sets of diagonal bracket wings, which can take a rotation around the axis between each other and be adapted to various archwire ligation methods. Results A new type of axis adjustable bracket was designed to have two sets of rotary diagonal bracket wings, and doctors can change the height and width of bracket slot by different ligation ways and choose different orthodontic correction systems. Conclusion When using the canine axis adjustable straight wire brackets, we can choose different orthodontic correction systems by different ligation ways.
