Abstract
An orthodontic self-ligating bracket for orthodontic treatment of maloccluded teeth. The bracket includes a bracket body, a bracket door, and a spring mechanism retained by the bracket door. The bracket body has a base on the bottom side of the bracket body that is contoured to attach to a surface of a tooth, a bracket slot on the top side of the bracket body extending in a mesiodistal direction and configured to releasably retain an archwire, and a bracket groove on the top side of the bracket body extending in an occlusogingival direction towards the bracket slot. The spring mechanism includes one or more springs that are configured to contact the bracket door and the bracket body. The bracket door can thus be retained by and slidably engage the bracket body between an open position and a closed position. One or more additional active spring members may also be provided.
