Fixed orthodontic retainers
are dental appliances used to maintain the position of teeth after braces or other orthodontic treatments have been completed. They are typically made of a thin wire that is bonded to the back of the teeth, usually the lower front teeth, although they can also be placed on the upper teeth.
Key Features of Fixed Orthodontic Retainers:
Material:
Wire: The retainer is usually made from a strong, flexible wire, such as stainless steel or a combination of materials that is durable and resistant to breakage.
Bonding: The wire is permanently bonded to the teeth using a dental adhesive, ensuring that it stays in place.
Purpose:
Prevent Relapse: After braces are removed, teeth can shift back to their original positions without retainers. A fixed retainer helps prevent this by keeping the teeth in their new alignment.
Long-Term Solution: Fixed retainers are often recommended for people who may have a higher risk of relapse or for those who prefer a non-removable option.
Placement:
Fixed retainers are typically placed on the lingual (inside) surface of the teeth, meaning they are not visible when you smile or talk.
The most common placement is on the lower front teeth (incisors), but in some cases, they can also be placed on the upper front teeth.
Advantages:
Constant Retention: Since fixed retainers are attached to the teeth, they provide continuous retention, unlike removable retainers that need to be worn consistently.
Convenience: There’s no need to remember to put the retainer in or take it out, making it a convenient option for those who may forget to wear a removable retainer.
Discreet: Because they are placed on the back of the teeth, they are not visible when talking or smiling.
Maintenance:
Oral Hygiene: Keeping a fixed retainer clean can be challenging. You will need to use special flossing tools (like floss threaders) to clean around the wire and between the teeth.
Regular Checkups: Regular dental visits are necessary to ensure the retainer is still intact and functioning properly, as the wire can sometimes break or become loose.
Duration:
Fixed retainers are often worn for several years, depending on the individual’s needs. In some cases, they may be worn indefinitely, especially if there’s a concern about the teeth shifting.
Risks:
Plaque Buildup: Poor oral hygiene around a fixed retainer can lead to plaque buildup, cavities, or gum disease.
Wire Damage: The wire can break, which may require a dental visit to repair.
Discomfort: Occasionally, the retainer may cause discomfort or irritation, particularly if it’s not properly adjusted.
Overall, fixed orthodontic retainers provide a reliable, long-term solution to maintain teeth alignment after orthodontic treatment, but they do require diligent care and attention to oral hygiene.
