Abstract
The present invention comprises a continuous series of alpha-numeric characters (such as letters or numerals) or symbols (such as company logos) that are formed in a manner such that the symbols or characters on the base of the bracket serve as texturing to facilitate bonding of the bracket with the tooth when the base of the bracket is attached to the tooth using an adhesive. In a separate aspect of the invention, a perimeter rail, and more preferably, a discontinuous perimeter rail may be used at the edge of the base. A method for forming a bracket is also provided.
