The Invisalign system works on the same principles of teeth straightening with metal braces. However, they are much more comfortable due not only to their clear design, no wires or metal pieces, but also because of the computer generated alignment progression.
Your Invisalign teeth straightening will progress as follow:
- First, we will take you bite impressions,
- Then, these impressions are laser scanned to generate 3D images in a computer,
- Finally, a series of clear trays (aligners) are created, each progressively moving your teeth towards the desired position.
Over the course of the Invisalign treatment, you will have between 12 and 30 set of aligners, each of them should be worn for the period of 2 weeks, which means the treatment time span can vary from 6 to 15 months, and you only need to visit the dentist every 2 to 3 months instead of every 3 to 4 weeks as required when wearing regular metal braces.
You will need to take the Invisalign trays off to eat; other than that, they stay on for 20 hours a day.
