What is the primary use of Essix retainers?

• A. Expansion of arches
• B. Retention after orthodontic treatment
• C. Correction of malocclusion
• D. Bonding braces

Answer: (B)

The main idea is that Essix retainers are used to keep teeth in their new positions after orthodontic treatment. They are clear, removable, vacuum-formed plastic appliances that fit over the teeth to prevent relapse once braces or aligners have moved them into place. Because the goal after active treatment is to maintain the corrected alignment, retention is the primary purpose of these retainers. They aren’t used to widen arches, correct existing malocclusion, or bond braces—those are accomplished with other appliances or procedures. The clear, discreet nature of Essix retainers also makes them a popular retention option, often worn full-time initially and then adults switch to nighttime use to maintain stability.
