Clear aligners such as Invisalign are known and popular due to the fact that they are more cosmetically appealing since they are almost invisible and they are more hygienic as they can be removed to easily brush and floss teeth.
The other feature of clear aligners is their faster speed of treatment. On average, aligners will be changed every 2 weeks as they move teeth step by step toward their final planned position. For traditional braces, the wires will be adjusted once a month for the same. range of movement. The reason that the aligners can be changed biweekly is that unlike their braces counterpart, they made of plastic with some flexibility and as teeth move they dispense forces more gradually. Brackets and braces are made of metal with no flexibility which make it longer to move the same range safely.
