There is a consensus among the OMS community that any type of oral surgery that is covered free is usually under the care of a "learning surgeon" or learning hospital. That's right, surgeons just completing there residency program, who can afford to make and learn there mistakes off YOU. If your case is complex, I wouldn't even fathom going through any type of university hospital or state funded medicaid (or military insurance). Simple movements (advancements or extractions) is pretty much all you'll get. If you need rotations, bone implants, bony contour issues, breathing problems, facial aesthetics, I would go to private practice and even then you'll want to research the surgeon and make sure he has the credentials and work to prove it, and I'd go as far as to refer his plan-out with another surgeon.
