Can a Person Start an Invisalign Program with One Dentist and Finish and Finish with Another?

I agree that it would have to be worked out ahead of time. I don't think you will find a dentist to work on your case unless the case is "transferred" over from Invisalign. Then the original dentist looses his records. It may be better to just work with the dentist in the state that you spend the most time in and see if you can spread out the appointments and maybe travel once in between. I sometimes keep in touch by cell phone photos when patients are out of town. If you are strict about wearing the aligners and keep in touch and get approval to continue by the dentist it could work. Otherwise you will end up wearing the aligners for a longer time and having to correct the problem when you get back in town. I hope this helps. It's better to work with one dentist.

Yes Invisalign can be transfered.  Usually this happens if somebody moves unexpectedly.  It's called a case transfer.  It should be avoided if possible because continuity of care is of great importance and there may be subtle differences on how providers get to a result.  Usually the cost will be greater if you use two instead of one.  Invisalign will transfer the case if all parties involved agree, but the fees have to be worked out with the respective individual clinicians.
