ABSTRACT:
The invention provides a ligature that has a defining formed shape and is affixed and integrated with the formed shape of the orthodontic bracket. The ligature can be repeatedly opened, closed, locked, or unlocked, in its integrated relation to the bracket. If necessary, the entire integrated ligature can be removed and replaced. Also, the removed ligature can be replaced by a similar ligature having a variance in the defining formed shape thereof. The integrated ligature has properties of, shape memory, elasticity, flexibility, and resistance to fatigue. The bracket has one or more arch wire receiving channels therein. The bracket also has, in addition to its relation to the integrated ligature, retention concavities in the upper and lower sides of the bracket to provide retention areas for auxiliary devices and/or supplemental ligatures. The integrated ligature and orthodontic bracket has a unique mechanical flexation response mechanism providing for continuous used and repeatable, opening, closing, locking and unlocking, of the ligature in its integrated relation to the bracket.
