My biggest problem is that the first guy over-rotated my upper jaw too far to the left. I get a cramped feeling like everything does not have enough room back there on that side. As well, instead of double jaw surgery (lower jaw is crooked), he tilted the upper jaw to match the cant of the lower jaw. Dumb idea. So what you end up with is and over-rotation, several mm cant in both jaws, and a misplacement of the midline by 3mm or 3 & a fraction of a mm more. I hope it would be deemed medically necessary. I'm not planning that way, but I hope so. The insurance lady at Arnett-Gunson seemed to help put my mind at ease a little bit by reassuring me that the have a good relationship with Anthem and have been applying to insurances for over 30 yrs. I hope I can get a better idea once I go in for a consult and they actually see my mouth in person.
Your plan won't be exactly this, but in my plan your situation would probably be accepted by insurance.
