ABSTRACT:
Self-ligating orthodontic brackets include a marking system for identifying which tooth or subset of teeth a specific bracket within a set of non-identical brackets pertains and/or for assisting in aligning a bracket on a tooth. The bracket includes a temporarily visible mark that is visible during placement of the bracket onto a tooth but which does not remain visible during long term use of the orthodontic bracket to straighten teeth. The marking may be removable or it may be hidden during use of the bracket to straighten teeth. The orthodontic brackets are advantageously included within a set or kit intended for placement onto the teeth of a patient. They advantageously include a ligation cover selectively movable between an open, non-ligating position relative to an arch wire slot in a bracket base and a closed, ligating position relative to the arch wire slot.
