Damon braces are passive, self-ligating brackets that do not require the need of a metal or elastic tie.
Metal Twin Braces:
Commonly used brackets which do require an elastic or metal tie to hold the archwire in place.
These are available in both damon self ligating, and traditional brackets. Although ceramic (clear) braces are not for everyone, they are a great option for adults and image concious patients.
