Invisalign Express has similar benefits to Invisalign but at a faster treatment time. That being said, Invisalign has its limitations. Below are the criteria for you to be a candidate:
Minimal rotation of the front teeth
Less than 2 mm of midline correction needed
Less than 2 mm of crowding or spacing per arch
Less than 1.5 mm of expansion needed per arch
If you don't meet the following criteria, then, traditional Invisalign express will be the appropriate treatment plan.
