Self-ligating brackets are associated with which primary advantage?

• A. Higher friction
• B. Reduction of friction
• C. More archwires required
• D. No effect on treatment

Answer: (B)

The main idea is that self-ligating brackets reduce the friction between the archwire and the bracket. In conventional brackets, elastic ligatures press the wire into the slot, creating friction and binding as the wire moves. A built-in clip or sliding mechanism in self-ligating brackets holds the wire with less contact pressure, allowing it to glide through the slots more easily. This reduced friction enables lighter, more continuous forces and can improve sliding mechanics, potentially easing tooth movement and saving chair time. It wouldn’t be correct to say friction is increased, that more wires are needed, or that there’s no treatment impact—the key advantage is the reduction of friction.
