The treatment isn’t over until the result is preserved

The duration and protocol for retainer wear is determined by the treating orthodontist and varies according to the complexity of the completed treatment. Research consistently shows that teeth have a natural tendency to relapse towards their pre-treatment position following any form of orthodontic movement. Most orthodontists recommend full-time wear for an initial period following active treatment, transitioning to indefinite nighttime wear thereafter. Your orthodontist will advise on the appropriate protocol for your specific case.

No — provided the post-treatment position of your teeth has not changed, the Angel Aligner Retainer can be reordered by your orthodontist without a new intraoral scan. Your orthodontist will confirm this at your next review appointment before submitting the reorder through the iOrtho™ platform. If your teeth have shifted, a clinical assessment will be required first.

The 1 mm specification is a clinically considered balance between durability and patient comfort. A thicker appliance resists the occlusal forces experienced during sleep and daily wear, reducing the risk of deformation or fracture over the extended periods characteristic of retention. At 1 mm, the retainer remains nearly invisible and comfortable enough that most patients adapt quickly to wearing it overnight. Patient comfort and compliance are directly linked — a retainer that isn't worn cannot protect the treatment result.

The Angel Aligner Pro plan includes up to 3 retainers as part of the comprehensive treatment package. Additional retainers can be ordered separately through your treating orthodontist at any time following treatment completion, without requiring a new intraoral scan.

Active aligner trays apply controlled biomechanical forces to move teeth progressively towards the treatment plan's target position. The retainer is a passive appliance — it applies no corrective force, but holds the teeth precisely in the position achieved at the end of active treatment. The Angel Aligner Retainer is fabricated from the digital records of the post-treatment tooth position, ensuring an accurate and stable fit.

The Angel Aligner Retainer is available as a standalone product, independent of the original treatment plan. Speak to an orthodontist who works with Angel Aligner — they will assess the suitability of a new retainer based on a current clinical assessment of your post-treatment tooth position. A new intraoral scan or impression may be required in this case, as there will be no existing digital record to reorder from.

From the patient's perspective, the key differences are comfort and discretion. The masterControl S™ phase of each 7+3 cycle begins with a gentle force application, which typically means less soreness in the first days after each tray change — a common point of discomfort with standard aligner systems. The aligners are nearly invisible when worn and are fully removable for eating, drinking, and oral hygiene. The angelButton™ integration, where elastic mechanics are required, removes the need for visible bonded buttons on the tooth surface, further supporting aesthetics during treatment.

No. The Angel Aligner Retainer is a medical device available exclusively through a qualified orthodontic professional. If you would like to reorder a retainer or have questions about your post-treatment retention protocol, speak to your treating orthodontist. They will manage the order through the iOrtho™ platform on your behalf.
