Am I Ineligible for Invisalign?

There is NO DOUBT you can use Invisalign. The only matter in question is whether or not all of your dental concerns can be resolved with Invisalign. I would suggest you consult a dentist or orthodontist who works with Invisalign (or another clear aligner system) AND conventional braces. Good luck, you will be VERY happy when the teeth are straight! 

While your case is not ideal, it does not appear at first glance to be impossible with Invisalign.  However, brackets and wires are more predictable, even the invisible (tooth colored) ones like 6 month braces.

Invisalign treatment procedures have improved significantly over the last decade and continue to advance. So the earlier dismissal of your 'eligibility" for Invisalign more than likely no longer applies. Also, you might take in to account that dentists, and some orthodontists, that are not experienced in managing Invisalign treatment  are less likely to recognize its potentials than a doctor who has extensive experience. I suggest you consult with an orthodonitist in your area whose practice includes a significant number of Invisalign patients. That way you are most likely to get the information you need to make an informed decision as to whether Invisalign is right for you.
