The Damon System is a fixed, passive, self-ligating method of correcting malocclusions. Passive self-ligating systems use brackets that do not require elastic o-rings to hold the wires in place. By not using the elastic o-rings, the wires freely slide through the slots without friction, which necessitates new mechanics to use the system to move teeth. In addition, no o-rings mean better oral hygiene, since they are a significant trap for oral bacteria. To hold the wires in place, the Damon System uses small sliding doors. The Damon System it is a great method to treat extreme malocclusions while reducing the treatment timing.
