Damon applianceis recommended for youth and adults. It is a self-ligating device, which consists of a bracket glued to the tooth with a special glue and an arch, which is attached to the bracket by means of a built-in lock flap. There is no ligature here, which is in conventional appliances. This solution makes it easier to maintain hygiene. These devices allow for greater expansion of the dental arches during treatment, which is beneficial in the case of large crowding of teeth with wide bone bases and often allows to avoid extraction. Damon self-ligating braces can be metal or aesthetic.
