Is it possible to get invisalign with capped teeth?

Yes: But the movement on these teeth may be limited due to the shape of the crown and the inability of reliably bonding attachments to those teeth. Have an orthodontic consultation to determine if the procedure will work in your situation.

Yes But: If the teeth are bridged the bridge will have to be separated and this is true or regular bands as well.

Talk to your ortho: The orthodontist should see your teeth before determining the best course of treatment.

Better approach: Better approach would be to straighten teeth before capping them, rather than making caps for teeth that are in wrong positions. Yes, invisalign will move capped teeth, but not bridges or implants, and with only about half the success of traditional braces. Please talk to a qualified orthodontic specialist before you consider tooth/jaw movement.

Not a problem: Invisalign (as well as fixed braces) work well with 'capped' teeth (teeth with crowns). Adhesives used to attach braces to crowns sometimes fail due to a compromised porcelain-cement bond. Invisalign, by virtue of the fact that it fits 'like a glove', completely surrounds the capped tooth and should effect its movement without any negative consequence.
