  • Patent number: 3946488
    Abstract: A two-part orthodontic appliance having a pedestal which is relatively permanently attached to a tooth, as by direct bonding or by a tooth band, and a bracket which is firmly but removably secured to the pedestal. A wide variety of lug configurations may be provided on the bracket, so that the appropriate bracket may be selected for the particular patient and tooth in question, as the orthodontic treatment proceeds over the weeks and months. The bracket may be readily replaced with one of another configuration to accommodate the changing forces that are needed to bring about the orthodontic correction. The bracket is secured to the pedestal by a locking member or detent formed from the bracket, which snaps into place over a detent edge formed on the pedestal. Removal of the bracket from the pedestal is accomplished by forcing the locking member back over the edge, and sliding the bracket off the pedestal.
