Switching from Braces to Invisalign Possible?

Switching from traditional braces to Invisalign is possible, however the cost associated with removing the braces and ordering Invisalign aligners is just not practical.

Once all the difficult expansion is done then you could possibly switch to invisalign to do the last stages of straightening. It will cost more money to start over with invisalign but nobody likes metal brackets anymore.

It seems from what you are describing that it is best to finish your treatment with metal braces as they are going to be the most effective way to improve your bite.

Ask your dentist or orthodontist what they think, as you might find that your case is too complex to change.
Usually there is NOT a credit from one system to the other, so you will effectively be paying twice for the same service (you are switching from one tool to another, but the same process, which is orthodontics).
If money is no object and your case is not too complex, there should be no problem switching.
