How does Invisalign or clear aligners work?
Clear aligners are built based on a digital simulation of teeth in their ideal positions. In order to fabricate the aligners, a digital scan, or an impression, of your teeth imported into software that allows an orthodontist or dentist to digitally move your teeth to their ideal positions. The software then generates several dental models in which your teeth have been gradually moved to their ideal position. A commercial or an in-house lab will 3D print these models and manufactures the aligners by a thermo vacuum forming process.
