A fixed or movable protective device worn to prevent the teeth from returning to their crooked position after braces treatment is completed.
Retainer (Reinforcement Appliance) Clinical Overview & Mechanism
When orthodontic forces are stopped, periodontium fibers tend to pull the teeth back (relapse) due to their elastic memory. To prevent this, a thin braided fixed wire (lingual retainer) is glued to the back of the lower front teeth and a transparent Essix plate is worn at night.
