    • An orthodontic bracket assembly is adapted for use with an arch wire in straightening a tooth having a crown long axis preferrably disposed at a particular angle with respect to an occlusal plane. The bracket assembly includes a base for fixing the assembly to the tooth and at least one tie wing having a fixed relationship with the base. The tie wing has a facial surface defined by a mesial edge, a distal edge, a gingival edge and an occlusal edge. At least one of the gingival edge and the occlusal edge are disposed at the particular angle with respect to at least one of the mesial edge and the distal edge of the tie wing, so that the facial surface of the tie wing has a generally rhomboidal configuration. This facilitates alignment of the assembly with respect to the occlusal plane and the crown long axis of the tooth.
    • 矫正托架组件适于与拱形线一起使用,以矫直具有相对于咬合平面优选地以特定角度设置的冠长轴的牙齿。 支架组件包括用于将组件固定到牙齿的基座和至少一个与底座具有固定关系的连接翼。 领带翼具有由中间边缘,远端边缘,牙龈边缘和咬合边缘限定的面部表面。 牙龈边缘和咬合边缘中的至少一个相对于连接翼的中间边缘和远端边缘中的至少一个以特定角度设置,使得连接翼的面部表面具有通常菱形配置 。 这有助于组件相对于牙咬合平面和牙冠长轴的对准。
