Invisalign is a way to orthodontically move teeth via clear, plastic retainers. Dr. Hanson is Invisalign certified. It is a great treatment option for patients with previous orthodontics that has since relapsed. It is also great for mild to moderate crowding, slight rotations, spacing, overjet, and overbite. Patients who are interested in invisalign treatment are evaluated by the doctor to see if they are good candidates. If you are deemed a candidate, quick impressions and photos are taken. The aligners are delivered 2-3 weeks later. The length of time to wear the aligners can range from 6 months to 2 years, but averages about a year.
