Invisalign: How it gets its move on


Invisalign is a series of aligners that incrementally move teeth as prescribed by the dentist based on the required results of the patient.

The aligners are replaced every two weeks... each aligner moves the teeth a little more towards the goal of straightening the teeth.

In our office, once all the information is gathered, patients can view the final results of their alignment on the computer imaging program before committing to treatment.

Invisalign - how it works


Invisalign is a computer generated system. A dental impression is scanned into the system from which a series of steps are designed and one clear plastic tray is manufactured by the computer for each step. You wear each tray for two weeks moving the teeth small amounts. It works quite well for most situations but not all orthodontic problems. The time to completion varies from 3-18 months depending on the complexity of the case.
