Abstract
An orthodontic appliance has a bracket portion with an archwire slot formed therein. The archwire slot extends in the mesial-distal direction of the appliance and is dimensioned to receive an archwire. The orthodontic appliance has at least one pair of tie-wings. Each tie-wing projects outwardly from the bracket portion on an opposite side of the archwire slot with respect to the other tie-wing. One pair of opposing shoulders are located on the mesial end of the bracket portion, and another pair of opposing shoulders are located on the distal end of the bracket portion. Each shoulder is located on an opposite side of the archwire slot relative to the other shoulder of the pair. Each shoulder is adapted to support a ligature thereon, and is dimensioned and located with respect to the archwire slot, so that the ligature is spaced above an archwire received therein. The orthodontic appliance is therefore permitted to move relative to the archwire during orthodontic treatment.
