The state of art technology used to straighten your teeth with almost clear braces. On an average this process takes 12-18 months, before you start the treatment a 3D simulation of your teeth movements is demonstrated, the software is capable of tentatively assessing the duration of treatment and projected result of treatment.
Invisalign braces are almost clear therefore are the ideal choice if you are looking for a discreet alternative to braces. As with other forms of orthodontic treatment Invisalign also recommends retention after completion of treatment.
