    • An orthodontic bracket is disclosed having three archwire retention channels in the mesial-distal directions, a central channel and two side channels. The two side channels each include a pair of spaced apart inverted archwire retaining regions having a recess that opens generally towards the bracket base. Each such recess is for grasping or holding an archwire therein. Each of the side channels has an archwire retaining ridge extending gingivally-occlusally along the adjacent side of the bracket base between the two retaining regions of the channel. For each channel, its retaining ridge exerts a force on a portion of an archwire facing away from the archwire portion residing in the recesses of the retaining regions of the channel. The force on the archwire is directed toward the interiors of the recesses of the retaining regions for assisting in seating the archwire in the recesses.
    • 公开了一种在近中远侧方向具有三个弓丝保持通道的正畸托架,中央通道和两个侧通道。 两个侧面通道各自包括一对间隔开的倒置弓形线保持区域,该保持区域具有大致朝支架底座开口的凹部。 每个这样的凹部用于在其中抓住或保持弓丝。 每个侧通道具有沿通道的两个保持区域之间沿支架底座的相邻侧边缘咬合地延伸的弓丝保持脊。 对于每个通道,其保持凸脊在拱形线的部分上远离位于通道的保持区域的凹槽中的弓丝部分施加力。 弓丝上的力指向保持区域的凹部的内部,用于辅助将弓丝安置在凹部中。

    • The present disclosure is directed, at least in part, to a self ligating orthodontic bracket having a rotatable member for securing an archwire within a slot of the bracket. Embodiments of the orthodontic bracket disclosed herein include a bracket body containing the archwire slot as well as tie wings for attaching various orthodontic devices (e.g., elastomeric bands) to the bracket. The rotatable member is rotatable in a first direction (e.g., counter clockwise) relative to a body of the bracket for securing or locking the archwire within the slot, and for rotating in an opposite direction (e.g., a clockwise direction) relative to the bracket body for unsecuring or unlocking the archwire so that it is substantially unrestrained from exiting the slot.
    • 本公开至少部分地涉及具有用于将弓丝固定在支架的狭槽内的可旋转构件的自身结扎正畸托架。 本文公开的正畸托架的实施例包括包含弓丝槽的支架主体以及用于将各种正畸装置(例如,弹性带)附接到支架的连接翼。 可旋转构件可相对于支架的主体沿第一方向(例如,逆时针)旋转,以将弓线固定或锁定在槽内,并且相对于支架沿相反方向(例如,顺时针方向)转动 本体用于不安装或解锁弓丝,使得其基本上不受限于从槽出来。

    • An orthodontic bracket is provided that includes a cover and a base, wherein the cover can be rotated over an arch wire slot in the base portion. The present bracket invention operates to close when a frangible portion is severed upon initiating rotation of the cover, such that the cover rotates about a hinge, which may include a pin or axle. In one embodiment of the invention, the pin or axle can be moved laterally and/or vertically after the frangible portion is severed. Preferably, the bracket is manufactured to form one piece, such as using an injection molding, machining, or casting process. The bracket offers economical advantages because additional subsequent assembly is not required to attach a cover to a base.
    • 提供了一种正畸托架,其包括盖和基座,其中所述盖可以在基部中的拱形线槽上旋转。 本发明的托架发明操作以在启动盖的旋转时切断易碎部分时闭合,使得盖围绕可以包括销或轴的铰链旋转。 在本发明的一个实施例中,销或轴可以在易碎部分断开之后横向和/或垂直地移动。 优选地,支架被制造成一体,例如使用注射成型,机械加工或铸造工艺。 该支架具有经济的优点,因为不需要额外的后续组装来将盖子附接到基座。
