Retention Treatment (Retainer)
What Is the Retention Period?
Retention treatment (retainer) is the stabilisation stage that supports teeth staying in their new positions after active orthodontic movement is completed. It is not a continuation of active bracket or aligner treatment; it aims to protect against the tendency of teeth to relapse.
Retention duration and use pattern are individual; it cannot be promised that the result will remain unchanged for life. Teeth and surrounding tissues adapt over time, but relapse risk does not disappear completely.
Fixed and Removable Options
Removable retainers may be Hawley (wire and acrylic) or transparent vacuum-formed plates; they are worn at night or for the duration recommended by the clinician. A fixed retainer is usually a thin wire bonded to the lingual surface of the lower front teeth; it remains continuously in place.
In some cases, a fixed and removable retainer combination may be planned. The choice is made according to occlusion, hygiene habits and relapse risk. The same retainer type is not used for every patient.
Use Duration and Compliance
More frequent use may be recommended at first; later the frequency may be gradually reduced. Mild tooth movement may occur during periods without retainer use. If the retainer is lost, broken or loose, the clinician should be contacted.
Not using a retainer increases relapse risk; long-term night use may be recommended by many clinicians. Relapse risk may be higher in adults; individual follow-up is important.
Care and Review
A removable retainer is cleaned daily with a soft brush and water; hot water may cause deformation. Floss or a special brush is recommended around a fixed retainer. At regular review visits, retainer fit and gum health are assessed.
Retainer wear or breakage may require renewal. Retention after orthodontic treatment is planned as an integral part of treatment.
Difference from Active Treatment
In active orthodontic treatment, teeth are moved; in retention, the current position is maintained. Bracket or aligner activation is not performed during retention. If retention is skipped, the achieved result may be partly or completely lost.
The patient and family are informed that retention is as important as active treatment. Alignment of expectations supports long-term success.
The retention plan starts when active treatment ends; retainer impressions may be taken after brackets or aligners are removed. Comfort adaptation may occur in the first weeks.
If retention is skipped after orthodontic treatment, the achieved result may be partly lost; therefore retainer use is an integral part of the plan.
