Invisalign for Bottom Teeth Only?

I have treated many single arch cases (only lowers or Only uppers).  The bite needs to be ideal to allow for single arch invisalign therapy.  In addition, the opposite arch should have decent alignment to begin with.   An Invislaign Consult  exam is all that is needed to see if you are a candidate. 

While it is technically possible to treat only the lower arch with Invisalign, generally it's not recommended except in specific cases. For example, if a patient has a fixed retainer on one arch, but a removable retainer on the other arch, but did not wear it, those teeth would shift. In that case, you may want to just treat the arch that has relapsed to that it fits back with the other arch that is still retained. Our upper and lower teeth fit together like a puzzle so that our bite is even on all teeth. So, if you treat only one arch, it could end up that that arch no longer fits the bite of the opposite arch. A good majority of cases will need both arches to be treated. 

Donna, thank you for a wonderful question. I wish you would provide a picture of the crowding.If it is a slight crowding, yes you can. In case it is a moderate to severe crowding I would not advise doing only lower teeth. Doctor, who will be doing your treatment, will have the same overhead cost and will need to spend the same amount of time whether he will treat one arch or both. Besides,  the best results can be achieved treating both arches at the same time.
