ABSTRACT:
An orthodontic bracket is disclosed having one or more projections which extend vertically from the posterior surface of the bracket body. The projections are used for producing a glue-line having a predetermined thickness measured between the posterior surface of the bracket body and the front surface of the tooth to which the bracket is directly bonded by glueing. The thickness of the glue-line is equal to the vertical displacement of the one or more projections from the posterior surface of the bracket base. The ends of the one or more projections touch the front surface of the tooth when the bracket is directly bonded to the tooth.
A process is also disclosed for attaching the orthodontic bracket of the present invention to the tooth of a patient undergoing orthodontic treatment.
