Clear aligners are removable plastic trays that are specifically designed to gradually move teeth into their desired positions. They offer a more aesthetically pleasing alternative to traditional braces, as they are virtually invisible when worn. The aligners are custom-made for each patient based on precise dental impressions or scans, allowing for a tailored approach to orthodontic treatment.

The process involves a series of aligners, each designed to shift the teeth slightly closer to the final position. Patients typically switch to a new aligner every few weeks, as prescribed by their orthodontist. This gradual movement helps ensure comfort and minimizes the discomfort often associated with traditional metal braces. Clear aligners also allow for easier maintenance of oral hygiene since they can be removed while eating and brushing.

While the other options detail different orthodontic devices—such as permanent braces or metal devices fixed to the teeth—they do not accurately describe clear aligners, which are distinguished by their removability and plastic composition. Similarly, orthopedic appliances are primarily focused on jaw alignment rather than direct tooth movement, further highlighting what makes clear aligners unique in orthodontic treatment.
