Invisalign’s patented system does not use guess work. It applies controlled force where and when it is needed to be most effective. The thermoplastic aligners provide gentle force in a specific direction to specific teeth at pre-determined points in the treatment procedure. Your trays will be custom-designed to straighten your teeth, your smile, and your bite. The results will be effective, timely and predictable. Your new aligners will arrive at your address about every two weeks to continue your treatment process. Visits every four to six weeks at our Carmichael dental office verify the progress of your orthodontic treatment.
