Invisalign Express has the same benefits that the original Invisalign treatment has but at a faster treatment time. That being said, this type of treatment has its limitations and it can only correct certain problems of the teeth. 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 these criteria, then, traditional Invisalign express will be the appropriate treatment plan.
