The Damon System of orthoontics is a fixed, passive, self-ligating method of correcting malocclusions. It uses brackets that do not require elastic o-rings to hold the wires in place. The system's light wires are as thin as .012 inches and are of increasing size. To hold the wires in place, the Damon System uses small sliding doors. 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. The addition of 'stops' on the wires helps prevent the wire from becoming displaced from its intended location.
