4 Months of Braces Followed by 9 Months of Invisalign - Good Plan?

It sounds like your orthodontist is trying to get rotation of teeth using conventional braces before finishing the case with Invisalign. Using Invisaling to rotate teeth, especially canines, used to be a very difficult proposition but the company has developed newer attachments that make this movement somewhat more predictable. I would suggest trying Invisalign first (with the newer attachments of course) and see if you can't complete the entire case with only Invisalign. If treatment objectives are not realized at the completion of Invisalign then brackets and wires can easily be used at the end.

While what you suggest will likely work just fine, the complexity of it all would increase the fee in my office.  You would likely save both time and money by just sticking to the braces and skipping Invisalign completely.

SInce you asked your initial question 12 months ago, I'm curious how things turned out for you. Please do share!

Adding some braces for a few months before, during or after the Invisalign can boost the speed of treatment. For example if teeth are rotated more than 45 degrees. Ask your doctor what specific goals he or she has for the braces phase of the treatment, so you both know when you will be set free. If the idea is just to get you in braces to sway you from Invisalign without a clear justification I would advise against that.
