摘要:
An orthodontic bracket includes a bracket body and a ligating member. The ligating member retains an archwire in an archwire slot and includes archwire control structure including projecting portions spaced apart in a mesial-distal direction with a recessed area therebetween. The recessed area and the projecting portions overlie the archwire slot. The recessed area may include a flat or a curved surface in a mesial-distal direction. The recessed area and projecting portions may define a radius of curvature that is less than the radius of curvature of the archwire seated in the slot. The archwire contacts one or both of the projecting portions resulting in a larger moment arm and better rotational control of the bracket with the force applied by the archwire.
