Brands of clear aligners like Invisalign are usually effective in correcting simpler or tipping movements of teeth.
What is Invisalign?
Clear aligners, also marketed under brand names like Invisalign & Clear Correct, are orthodontic devices that are a transparent, plastic form of dental braces used to adjust teeth. They are effective for moderate crowding of the front teeth, but less effective than conventional braces for several other issues and are not recommended for children. In particular they are indicated for “mild to moderate crowding (1–6 mm) and mild to moderate spacing (1–6 mm)”, in cases where there are no discrepancies of the jawbone. They are also for patients who have experienced a relapse after fixed orthodontic treatment.
How Does It Work?
Clear-aligner treatment involves an orthodontist or dentist taking a mold of the patient’s teeth, which is used to create a digital tooth scan. The computerized model suggests stages between the current and desired teeth positions, and aligners are created for each stage. Each aligner is worn for 20 hours a day for two weeks. These slowly move the teeth into the position agreed between the orthodontist or dentist and the patient. The average treatment time is 13.5 months.
