Invisalign can correct uneven teeth in a relatively short amount of time, without the need for metal braces and wires. The special braces or ‘aligners’ are made of a special hardened transparent plastic.
How is it performed?
First, your dentist will take several x-rays, and 3-D photographs of your teeth, before sending them to Align Technology, the manufacturers of Invisalign. At Align Technologies, the 3D images, photos, and x-rays are uploaded into a computer, which is used to create a dynamic 3D model of your mouth. The technicians then use this computer model of your mouth to plan the re-alignment of your teeth, step-by-step, as directed by your orthodontist. With the assistance of the software, they will track every movement of the teeth through the various stages of re-alignment, and record it for your dentists’ approval.
This simulation is then sent in full to your orthodontist, who reviews it a final time, before giving them the go-ahead to make your aligning molds. Using the approved 3D simulations, a special plastic model is made for each stage of your treatment, before being checked and sent to your orthodontist.
Depending on how complex your treatment is, the average time for Invisalign is around a year.
