After braces are removed, the retention phase ensures teeth remain in their corrected positions. Custom-made retainers, typically composed of transparent plastic and thin wires, are used for this purpose.
Retainers are worn for varying durations, depending on treatment type and patient age. Compliance is crucial for successful treatment outcomes.

Types of retainers include:

• Hawley retainer: Features a metal wire on an acrylic arch, adjustable by the orthodontist.
• Essix retainer: Made of clear PVC trays custom-fit over the arch, offering discreetness but prone to breakage.
• Fixed retainer: Affixed to the tongue side of teeth, usually for rapid or significant tooth movement cases.

Considerations when using a retainer:

• Avoid losing the appliance by storing it in its case when not in use.
• Refrain from drinking while wearing to prevent acid exposure and tooth decay.
• Do not eat with a retainer to avoid damage and hygiene issues.
• Properly clean retainers to prevent bacterial buildup, using appropriate cleaning agents.
• Wear the retainer as directed to stabilize teeth in their new alignment and avoid regression.
