Orthodontic progressive aligner

Orthodontic progressive aligners are custom-made, transparent appliances designed to gradually correct tooth alignment and jaw positioning through a series of sequentially worn trays. Each aligner is worn for a set period before being replaced by the next in the series, applying gentle pressure to move teeth into desired positions for treating malocclusions such as overbites, underbites, crowding, or spacing issues.

These devices are patient-specific, fabricated from dental impressions or scans, and intended for self-removal and replacement by the user. They are typically supplied as a series of aligners for progressive treatment and may include a final retainer; regulatory classification depends on jurisdiction and specific device characteristics, but all are considered reusable within their intended use cycle.
