How does Invisalign effectively move teeth?
Like brackets and arch wires, the Invisalign aligner moves teeth through the appropriate placement of controlled force on the teeth. The principal difference is that Invisalign not only controls forces, but also controls the timing of the force application. With each aligner, only certain teeth are allowed to move, and these movements are determined by the orthodontic treatment plan for that particular aligner. This results in an efficient force delivery system.
