The Damon Passive Self-Ligating Appliance System

The Damon System (Ormco Corp., 1332 South Lone Hill Ave., Glendora, CA 91740-0000) is a passive self-ligation system that was originally introduced in 1994. Since then, both the bracket and the philosophy behind the system have undergone continuous evolution. If the development of the Edgelok (Ormco Corp.) appliance by Wildman in 1972 and the development of the SPEED (Strite Industries Ltd., 298 Shepherd Ave., Cambridge, Ontario, N3C 1V1 Canada) appliance by Hanson in 1980 marked the start of modern self-ligating appliances, then the Damon System has probably been responsible for a fuller understanding of the influence of passive self-ligation on orthodontic treatment and the increasing popularity and utilization of the concept.
