Abstract
An orthodontic bracket has a front side part, a bump portion, an inner side part which are formed on a ceiling face of a guide portion in such a manner that the front side part, the bump portion, the inner side part are formed in order in a guiding direction to which a clip is guided by the guide portion. The orthodontic bracket further has a sliding-rotation supporter provided at the lower end of the clip. When the sliding-rotation supporter slides on the ceiling face and gets over the bump portion from the front side part to reach the inner side part of the ceiling face, the clip can press the archwire down toward the bottom of the archwire slot.
