Abstract
This invention relates to a novel bracket assembly for producing tooth movement in the treatment of dental malocclusions. A dual bracket system includes a primary and secondary bracket. An archwire is received in the secondary bracket. The primary bracket is attached to the tooth and the secondary bracket engages the primary bracket, thereby holding the secondary bracket and the archwire in place. Various configurations of the secondary bracket can be used with the primary bracket for producing desired tooth movements. A novel pin and ligature assembly can be used with the bracket assembly or a conventional bracket.
