If you need braces, use an orthodontist (I did), and make sure you have a treatment plan of some sort outlined from them (preferably in writing where you can discuss it). The Invisalign 3D scan is worthless compared to impressions. Also, adjustments are made at the end of the process (Invisalign euphemistically refers to them as refinements) after the damage is done. The metal or clear brackets can be adjusted during the treatment process to remedy problems that may arise.
I sincerely wish I had just lived with my bite problem and had never let the orthodontist touch what were once pretty teeth. I try not to smile or laugh showing my teeth anymore.
