Orthodontics: Appliances and Assisting · CDA

Why might an orthodontist choose a self-ligating brace system over traditional ligated brackets?

Self-ligating brackets are always the less expensive option
They reduce friction and may speed up tooth movement
They completely remove the need for any archwires at all
They entirely avoid the need for a retention phase later

Show answer and explanation

Correct answer: They reduce friction and may speed up tooth movement

Self-ligating braces use brackets that hold the archwire without elastic ligatures, reducing friction. This can result in more efficient tooth movement and possibly shorter treatment times.
