Damon system


Written By: Ehsan Jahandarpour

The Damon system of orthodontics is one of many fixed, passive, self-ligating methods 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 claims are that the wires freely slide through the slots without friction but may not be correct as it allows more rotation or tipping of teeth (and therefore some potential loss of precision of movement) before the bracket edges contact the wire resulting in friction. No o-rings they claim means better oral hygiene, but the research is equivocal finding both for and against. To hold the wires in place, the Damon System uses small sliding doors. The addition of ‘stops’ on the wires helps prevent the wire from becoming displaced from its intended location.
