According to the American Association of Orthodontists, 20% of new patients are adults. Which is probably why we are often asked about Invisalign. How does Invisalign work? The short and simple answer is, it is a sequence of several aligners custom made for each individual that accomplishes this goal.
When physiologic forces are applied in a given desired direction, teeth move. It doesn’t matter whether these forces are applied as the “pull” of archwires (braces) or the “push” of aligners (Invisalign). According to All In One Dental Innovations, “While there are a few movements that the pull of archwires can biomechanically accomplish better than Invisalign – such as eruption of an impacted tooth, there are many more movements that Invisalign can perform better, precisely due to the infinite number of tooth contacts.”
With braces, the flex of the distorted wire as it returns to its original position, is the force generated to move the teeth. When using Invisalign, the force needed to move the teeth is generated by the flex of the resilient plastic over the teeth. Just as with wires, each tray can only move the teeth a predetermined amount. Therefore, the further the teeth need to move the more trays are needed.
