The Invisalign Process Is Easy And ComfortableThe Invisalign System combines advanced 3-D computer graphics technology with 100-year-old science of orthodontics. Invisalign aligners are designed to move your teeth in small steps to the desired final position prescribed by Dr. Ryan. Each aligner is precisely calibrated and manufactured to fit your mouth at each stage of the treatment plan. Your aligner is worn for about two weeks and only taken out to eat, brush and floss. As you replace each aligner with the next, your teeth will begin to move gradually — week-by-week until the final alignment prescribed is attained.
