Self-ligating brackets are defined as "a dental brace, which generally utilizes a permanently installed, moveable component to entrap the archwire". Self-ligating brackets have also been designed which do not require a movable component to hold the wire in place. Self-ligating braces may be classified into two categories: Passive and Active.
These braces were typically made from stainless steel but, in some cases, are available in ceramic or polycarbonate.
