selfligating

Self-ligating refers to a type of orthodontic bracket system in which the bracket includes a built-in mechanism to secure the archwire, eliminating the need for traditional elastic or metal ligatures. The archwire is held in place by a clip, sliding component, or latch integrated into the bracket.

There are two main approaches within self-ligating systems: passive and active. Passive self-ligating brackets use a non-elastic clip that simply holds the wire without applying additional force to it; the wire can move more freely within the bracket, potentially reducing friction during tooth movement. Active self-ligating brackets employ a clip or door that applies gentle pressure on the wire to influence movement.

Potential advantages cited for self-ligating braces include reduced friction between the wire and bracket, which may enable smoother sliding of teeth, elimination of elastic ligatures that can stain or harbor plaque, and easier hygiene around the brackets. Some patients and clinicians report shorter chair time for adjustments and greater comfort during treatment, though evidence on reduced overall treatment duration is mixed and varies by case and system.

Limitations and considerations include higher upfront costs compared with conventional brackets, variable evidence regarding time savings, and the possibility of mechanical issues such as clip wear or breakage. They also require proper maintenance and cleaning to prevent plaque buildup around the mechanism. As with any orthodontic treatment, suitability depends on the individual’s malocclusion, treatment goals, and the clinician’s experience with the system.
