ABSTRACT:
An orthodontic bracket is provided for use with an arch wire to apply corrective forces on a tooth. The orthodontic bracket includes a pair of spaced apart, generally vertically oriented tie-wings for attachment of a force transmitting member or a fastening member to either or both of the tie-wings. Each of the tie-wings includes a slot therein for receiving the arch wire. The orthodontic bracket also includes a pair of extension members engageable with the arch wire to control rotation of the tooth. One of the extension members projects mesially from the bracket and the other extension member projects distally from the bracket.
