After ordering your impression kit, it will be delivered to you in 3-5 business days. From the day we receive your teeth impressions, a treatment preview with a smile projection will be with you in 12-14 business days, and after you approve the treatment preview and pay for the aligners, they will be with you in 17-21 business days. So the whole process normally takes 5-7 weeks unless there aren't any unforeseen circumstances.
