Fixed Retainer
A thin wire bonded to the inner surface of the teeth after orthodontic treatment. It is invisible from the outside, works 24/7, and discreetly maintains your treatment results.
Protect Your Orthodontic Results Long-Term with Retention Treatment
When orthodontic treatment is complete, the teeth have reached their new positions; however, treatment does not end entirely at this point. As the surrounding tissues, bone, and muscle balance try to readjust over time, teeth may tend to return to their old positions. Retention treatment is applied to control this movement and support the permanence of the results achieved. Fixed retainer wires and, when needed, additional protective retainers are important parts of this process.
After braces or Invisalign treatment, the areas where teeth are most likely to shift back are identified. This guides the retainer design and placement strategy.
A thin wire is carefully bonded to the back of the front teeth. It is invisible from the outside and provides continuous 24/7 protection without relying on patient compliance.
In many cases, a fixed wire alone is not enough. A Vivera clear retainer is added for nighttime use to cover all teeth and provide additional support.
Regular check-ups ensure the wire remains intact, oral hygiene is maintained around the retainer, and teeth stay in their corrected positions over the years.
What Is Retention Treatment?
Retention treatment is the protective phase applied after orthodontic treatment to maintain the teeth in their new positions. During this process, fixed retainer wires, clear retention retainers, or the use of both methods together can be considered. The goal is to help prevent the teeth from becoming crowded again over time and to make the treatment result more stable.
Because after orthodontic treatment, teeth may naturally tend to return to their old positions. Retention treatment helps reduce this risk.
A retainer wire is a thin fixed wire typically bonded to the back surface of the front teeth. It helps maintain tooth position without being visible from the outside.
Generally, the protection phase after orthodontic treatment is important. Which type of retention is suitable is determined based on the patient.
Create the Right Protection Plan for You with a Detailed Evaluation
The most important aspect of retention treatment is correctly determining which areas the teeth tend to shift back in and which protection method is more suitable. Because while a fixed retainer alone may be sufficient for some patients, additional clear retainer support may also be needed in other cases. For this reason, the post-treatment protection plan should be considered a natural continuation of active orthodontic treatment.
- Post-treatment tooth stability is evaluated.
- Areas at risk of relapse are analyzed.
- Fixed wire, retainer, or combined protection options are planned.
- Long-term protection recommendations with regular follow-up are established.
Why Is the Retainer Wire So Important?
Results achieved with Invisalign or braces are not permanent without the retention phase. After orthodontic treatment, teeth have not yet “settled” into their new positions. The bone, gum fibers, and periodontal ligaments surrounding them remember their old structure and try to pull the teeth back. The retainer wire resists this pull-back force and keeps the teeth in place.
When retainers are not used, teeth begin to shift. This is called orthodontic relapse. Relapse progresses fastest especially in the first 1-2 years, but can continue even years later. For this reason, many orthodontists recommend that the retainer wire remain in place for life.
Fixed Retainer vs. Removable Retainer
A fixed retainer wire is a thin wire bonded to the back surface of the teeth. It cannot be removed by the patient, is invisible from the outside, and provides continuous protection. Its biggest advantage is that it does not depend on patient compliance; teeth are protected as long as the wire is in place.
A removable retainer is a clear tray worn at night. At Doredent, Invisalign Vivera clear retainers are used for removable retention. In many cases, the safest approach is to use both methods together: the fixed retainer wire provides protection throughout the day, while the Vivera retainer provides additional support at night.
If the Retainer Wire Falls Off or Breaks
Partial detachment or complete loss of the retainer wire immediately increases the risk of teeth shifting. In this situation, you should contact your orthodontist as soon as possible. Every day that passes without intervention increases the likelihood of teeth moving back toward their old positions. At Doredent, same-day retainer wire replacement or repair can be performed.
Tartar buildup can occur behind the retainer wire. This is a normal situation and can be cleaned without damaging the retainer wire during professional scaling performed every 6 months. The dentist performing the cleaning simply needs to be careful not to break the wire.
Retainer Wire and Oral Hygiene
Since the retainer wire is on the back of the teeth, cleaning that area requires a bit more attention. Dental floss may not be able to pass under the wire; in this case, the use of interdental brushes or a water flosser (oral irrigator) is recommended. Inadequate hygiene increases cavity risk just as in crowded teeth. Any cavities that develop can be treated with a filling at an early stage.
Through regular check-ups, the condition of the retainer wire, tooth positions, and oral hygiene are evaluated together. In pediatric and adolescent patients, informing both the child and the parent about retainer use is important.
Frequently Asked Questions
We have compiled the questions we receive about this treatment and answered them as openly and transparently as possible.
It is placed to help maintain the teeth in their new positions after orthodontic treatment.
Generally, it is not noticeable from the outside since it is placed on the back surface of the teeth.
It is very important. The retention phase plays a critical role in the long-term preservation of results achieved through active treatment.
The protective effect may diminish and small movements in the teeth may begin. For this reason, it is important to have it checked without delay when noticed.
For some patients, yes; in other cases, planning it together with clear retention retainers may be more appropriate.
Yes. The integrity of the retainer, hygiene, and tooth stability should be evaluated through regular check-ups.
