Invisalign provides a series of 18-30 custom-made, transparent aligner trays that adjust your teeth incrementally to reduce crowding and straighten your teeth. The results are the same as those achieved by metal braces worn to adjust teeth, but with some important differences in convenience and esthetics.
Invisalign uses the same biomechanical force as braces, but the aligners are clear so they do their job without marring your appearance, and they pop out easily for cleaning. Poor oral hygiene is a considerable side effect of wire braces. Food can get stuck between all the elements of the braces, allowing tartar buildup and decay. The Invisalign trays come out easily, so patients remove them before eating and then snap them back in after brushing their teeth.
With Invisalign, Dr. Hassan takes an image of the teeth configuration and scans it into a computer. The computer software designs a series of clear plastic aligner trays customized to fit the needs of the patient. The goal is to apply a small amount of force to the teeth, loosening them and causing them to move. With each successive adjustment, new bone begins to form around the tooth securing it in place.
The patient wears each aligner for at least 20 hours a day for two weeks. Each aligner changes the position of the teeth slightly, and at the end of the treatment when all the trays have been worn, the teeth are straight.
It's up to Dr. Hassan to decide if Invisalign is a good choice for her patients in need of alignment. She evaluates the oral health of each patient and the extent of the adjustment necessary. Invisalign is not a good choice for severe gaps, for example, because they simply require more movement than this process can supply.
Age is another factor. Invisalign is a practical choice for older teens or adults but not for younger patients because their teeth are still growing. Invisalign takes dedication on the part of the patient, too. They need to make regular trips to the office and be diligent in caring for their aligners. Younger patients tend to lose their aligners or fail to maintain them properly, which can interfere with the overall treatment.
