ABSTRACT:
A low profile self-ligating orthodontic bracket having a base plate which may be adhesively attached to the lingual or labial surface of a tooth, and which includes a transverse slot extending across the front surface of the base plate for receiving an arch wire, and which includes a cover plate extending over the slot and resiliently self-biased against the front surface of the base to force the arch wire down into the slot. The cover plate may be turned outwardly by the orthodontist to permit the arch wire to be inserted into the slot or removed from the slot, and when the cover plate is released, it moves with force against the front surface of the base to trap the arch wire in the slot.
