Abstract
An orthodontic buccal tube has a first passage for receiving a main arch wire, a second passage for receiving either a lip bumper or a facebow, and a third passage for receiving an auxiliary or segmented arch wire. The second passage includes an enlarged, generally frustoconical mesial entrance, and the third passage includes a mesial opening that is located at least partially in the enlarged entrance. As such, the third passage can be spaced relatively close to the second passage while the enlarged mesial entrance of the second passage facilitates the insertion of the facebow or the lip bumper.
