Abstract
An orthodontic bracket for coupling an archwire with a tooth includes a bracket body that has an archwire slot adapted to receive the archwire. A movable member is engaged with the bracket body and is movable between an opened position and a closed position. The bracket body and movable member are made from a transparent or translucent ceramic for improved aesthetics. The bracket body may include one or more stop surfaces that limit movement of the moveable member in the gingival direction. The bracket body may include a support surface that is positioned lingually of a labial edge of the archwire slot. The moveable member may include a bracket-engaging portion having a first surface confronting the bracket body and a slot-covering portion having a second surface confronting the archwire slot, the first and second surfaces being offset from one another.
