Not a good idea to have Invisalign on bottom teeth only
As an Advantage Invisalign provider, I don't do single arch cases and here's why.
If you fix the lower arch and not the upper one, you are having to rely on the position of the upper teeth to dictate the position of the lower teeth. If you are paying good money to straighten your teeth, you need to do both arches so that you will have a successful treatment.
To you, the patient, the upper teeth may look fine to you, but to a trained eye who understands tooth movement, you have to trust us...
