پس از پایان درمان ارتودنسی و برداشتن براکتها، دندانها تمایل طبیعی دارند تا به موقعیت قبلی خود برگردند. برای جلوگیری از این بازگشت، متخصص ارتودنسی از وسیلهای به نام نگهدارنده یا ریتینر (Retainer) استفاده میکند. Among the different types of retainers, the fixed orthodontic retainer or wire behind the teeth is one of the most lasting and effective methods to maintain the treatment result.
The fixed retainer consists of a thin metal wire that is installed with special resin glue behind the front teeth of the upper or lower jaw. Unlike removable retainers, this retainer remains permanently in the mouth and does not need to be placed and removed daily, so the possibility of the teeth returning to their previous position is minimized.
Relying on the practical experience of Dr. Farinaz Shirban, orthodontist in Isfahan, and using the world's standards, this article has been written as a comprehensive guide for fixed orthodontic patients. In this guide, you will learn about pros and cons, care methods, replacement time and key tips to maintain orthodontic results.
Global statistics of the use of fixed retainer after orthodontics
Global research shows that more than 70% of people continue to use fixed retainers to maintain the results of their treatment after finishing orthodontic treatment. In Iran, the situation is almost the same, but internal surveys show that many teenagers still do not adhere to the regular use of retainers, which can jeopardize the result of hard work in orthodontic treatment.
In Dr. Farinaz Shirban's clinic in Isfahan, more than 65% of patients prefer to use a fixed retainer to continue their orthodontic treatment. Their main goal is to prevent the front teeth from coming back and to maintain stable orthodontic results. This statistic shows that choosing the type of preservative and adhering to regular use has a direct role in the long-term success of the treatment.
What is fixed orthodontic retainer and how does it work?
The wire behind the teeth or the orthodontic wire holder is one of the most important tools after the end of the orthodontic treatment. This retainer is installed behind the front teeth of the upper or lower jaw with a special orthodontic retainer adhesive, and unlike orthodontic plate retainers or removable retainers, it remains permanently in the mouth. For this reason, the retainer behind the tooth reduces the possibility of the teeth moving to the previous position and ensures the long-term stability of the orthodontic results.
This type of retainer is made of thin metal wire and can be used for each individual tooth or as a complete orthodontic jaw retainer. Its precise installation is very important, because any problem in the glue or wire can cause the unwanted displacement of the teeth.
Important points about wire:
- Duration of using a fixed retainer: Most patients need to use it for several years, even permanently.
- Fixed retainer hygiene: Careful brushing, flossing, or tools such as a Floss Threader are essential for cleaning wires.
- Orthodontic holding space: The distance between the wire and the tooth should be adjusted properly so that both tooth movement is limited and plaque accumulation is low.
- Pain and side effects of orthodontic retainer: Some patients feel a little pressure or discomfort in the first days, which usually goes away with time.
- Fixed lower or upper jaw retainer: depending on the position of the teeth and the diagnosis of the specialist, the retainer can be installed behind the lower jaw teeth, the upper jaw or both.
According to the practical experience of Dr. Farinaz Shirban, wire behind the teeth is the best option for patients whose front teeth are prone to displacement and need long-term stability.
Advantages and disadvantages of fixed orthodontic retainer
wire behind the teeth, due to its high durability and permanent installation behind the teeth, is one of the most effective tools to maintain the results of orthodontic treatment. This type of retainer stabilizes the position of the teeth continuously and minimizes the possibility of the teeth returning to their previous position.
However, using them comes with challenges. Cleaning under the wires requires precision and special tools, and there is a possibility of breaking the fixed retainer or eroding the resin adhesive. Also, if there is no accurate installation or insufficient care, some permanent retainer complications may occur, such as gum irritation or slight movement of the teeth.

These wires are designed according to the shape of the teeth and the treatment plan, and they can be single-stranded or multi-stranded. The CAD/CAM system is simply a method of digital wire design and molding, not wire material.

How to clean and care for fixed orthodontic retainer
The orthodontic wire retainer, despite its high durability and permanent performance, requires careful care so that the teeth remain healthy and the retainer wire and adhesive are not damaged. Maintaining proper hygiene, using auxiliary tools and regular examination by a specialist is the key to maintaining the results of orthodontic treatment.
Key tips for fixed retainer hygiene:
- Regular brushing:
The teeth and their backs, where the wire is attached, should be brushed at least twice a day. It is necessary to use a soft toothbrush and the right angle to clean the glue and wire. - Dental floss with fixed retainer:
The use of Floss Threader or Super Floss is recommended so that the dental floss can easily pass under the wire and remove the plaque between the teeth and around the adhesive. - Washing and plate control:
After every meal, especially if sticky or sweet foods have been consumed, the mouth should be rinsed with water or mouthwash to prevent the accumulation of bacteria and decay. - Periodic examination by an expert:
Even if the patient observes good hygiene, the wire or adhesive may have slight deformation or invisible damage. It is recommended to visit at least once every 6 to 12 months. - Avoid excess pressure:
Avoid chewing hard, sticky food or opening objects with your teeth so as not to damage the retainer wire and glue.
Golden tips from Dr. Farinaz Shirban:
- Any accumulation of mass or discoloration around the retainer wire can be a sign of the beginning of decay.
- If a part of the glue is loose or broken, do not try to remove it yourself and immediately consult a specialist.
- It is better to perform a specialized scaling once every 6 months to preserve the durability of the wire.
Cleaning the wire behind the teeth seems simple, but it is actually one of the key steps for its long-term durability. With daily care and regular visits, the retainer can last for years without needing to be replaced.
