Orthodontic Retainers | |
Orthodontic retainers are custom-made devices, usually made of wires or clear plastic, that hold teeth in position after surgery or any method of realigning teeth. Once a phase of orthodontic treatment has been completed to straighten teeth, there remains a lifelong risk of relapse (a tendency for teeth to return to their original position) due to a number of factors: recoil of periodontal fibres, pressure from surrounding soft tissues, the occlusion and patient’s continued growth and development. By using retainers to hold the teeth in their new position for a length of time, the surrounding periodontal fibres adapt to changes in the bone which can help minimize any changes to the final tooth position after the completion of orthodontic treatment. Retainers may also be used to treat overjets. Removable retainers include Hawley, Vacuum-formed, Begg and Barrer. They provide orthodontic retention when worn and they can be taken in and out of the mouth. They can be worn part-time or full-time if required or as advised by the orthodontist. In comparison to fixed retainers, removable retainers are easier to clean. Fixed retainers Fixed retainers are often used to provide orthodontic retention and avoid relapse.[14] They commonly consist of a wire bonded with acid etch and composite to the lingual/palatal surface of the anterior teeth. In fixed retainers, composite is usually placed to bond and to cover the wire, whilst ensuring no interference in the interdental space. Fixed retainers are used in situations where instability is more likely, such as severe rotations, periodontal disease and median diastemas. Occasionally the patient will require a removable retainer as well. Fixed bonded retainers can be designed with a smooth wire or flexible spiral wire which is also known as multi-strand wire. The most commonly used are multi-strand wire bonded to all six anterior teeth or a round stainless-steel wire bonded to the canines only. Although fixed retainers depend less on the patient’s cooperation for regular wearing, they are more difficult to clean and therefore need more attention from the patient to prevent plaque accumulation and subsequent gingival inflammation. Maintenance Relapse can occur if retainers are not worn regularly post-treatment. The orthodontist may advise wearing the retainer for a set period of time or indefinitely after orthodontic treatment. Recent innovations of a Smart Retainer Case that utilizes: IoT, motion sensors, and a mobile application to track, remind, and reward patients, might be the most effective way of keeping post-orthodontic patients engaged with their final retention and continued wear of their removable retainer. If not cleaned properly, retainers can act as a food reservoir and lead to caries and gingival inflammation. Cleaning options for removable retainers include retainer/denture tablets, the use of a toothbrush and fragrance-free soap or non-abrasive toothpaste. If the water used to clean the retainer is too hot, it may cause shrinkage. If the retainer is removable, it should be cleaned before inserting. If the retainer is fixed and cannot be removed, it should be cleaned during the nighttime home care routine. To clean a retainer use a wet toothbrush and gently scrub all surfaces of the retainer to remove any plaque and bacteria. A non-abrasive toothpaste should be used when cleaning a retainer. Alternatively, a mild soap or a brush dipped in mouthwash can also be used to clean it. When not in use keep the retainer in a dry container. Avoid leaving it in high temperatures or in the sun. Do not soak a retainer in liquids overnight. This will ensure the material will stay intact.
