Abstract
In one embodiment, a pre-engaging orthodontic bracket includes a body having a lingual surface for attachment to a tooth, a pair of laterally spaced gingival tie wings and a pair of laterally spaced occlusal tie wings. The gingival and occlusal tie wings project from a labial surface of the body. An archwire slot extends mesiodistally across the body and between the gingival and occlusal tie wings at opposed mesial and distal sides of the body to accommodate an archwire. A pivot pin extends between a pair of the tie wings at opposed mesial and distal sides of the body. A shutter is moveable relative to the body between an open position in which placement and removal of an archwire into the archwire slot is facilitated and a closed position in which placement and removal of an archwire into the archwire slot is inhibited.

An orthodontic bracket comprising:
- a body having a surface for attachment to a tooth and defining an archwire slot;
- at least one tie wing coupled to said body;
- and
- a resilient locking shutter having one end pivotally engaged with said tie wing and an opposing end positioned in said archwire slot, said locking shutter being pivotable between an open position where access to said archwire slot is permitted and a closed position where access to said archwire slot is inhibited, said locking shutter resiliently engaging said tie wing in its open position.
An orthodontic bracket comprising:
- a body having a surface for attachment to a tooth and defining an archwire slot;
- at least one tie wing coupled to said body, said tie wing including a labial surface;
- and
- a locking shutter having one end pivotally engaged with said tie wing and an opposing end positioned in said archwire slot, said locking shutter being pivotable between an open position where access to said archwire slot is permitted and a closed position where access to said archwire slot is inhibited, said locking shutter sliding along said labial surface when in a position between said open position and said closed position.
