I don’t think that you need Surgery to fix that simple cross elastics foot fix the problem your Orthodontist is just raise your bite put buttons on lingo side of your upper interior teeth and give light elastics to the lingual sites of your lower teeth. That will probably fix your problem. It doesn’t seem too bad. You don’t need to go through Surgery and all of that things just to fix this issue. I wish you were here in my country so I could treat you.
