aligners

Aligners are a type of dental appliance used to straighten teeth and correct certain bite problems. They consist of a series of clear, removable plastic trays that fit snugly over the teeth. Each aligner is custom-made from digital scans or impressions according to a treatment plan that maps the intended tooth movements over time.

Treatment typically begins with an evaluation by a dentist or orthodontist. Digital scans or physical impressions are converted into a 3D treatment plan, which defines the sequence and number of aligners needed. After fabrication, the patient wears each aligner for about one to two weeks, with an average daily wear of 20 to 22 hours. Aligners are removed for eating and cleaning. Regular check-ins monitor progress, and refinements or additional aligners may be required if images show incomplete movement or relapse.

Indications and limitations: Aligners are commonly used for mild to moderate crowding, spacing, and some bite issues. They are less suitable for severe malocclusions, complex bite corrections, or movements requiring significant vertical control without adjuncts. Success depends on patient compliance, oral hygiene, and, in some systems, the use of attachments or elastic bands to aid movement.

Retention and care: After active treatment, a retainer is usually recommended to maintain results. Aligners should be cleaned regularly and kept away from extreme heat. Costs vary by region and provider, and can be similar to or higher than traditional braces, depending on complexity and treatment length.
