Cost of surgery would depend on not only where the surgery is performed but the extent of the surgery based upon the patient's specific requirement. In my case mine was done at Mayo / St. Mary's and roughly $250K, perhaps a bit more. My additional dental prosthetics was out of pocket cost roughly the price of a car. Hopefully it will last considerably longer. I don't have money to throw away. One must consider quality of life and priorities.
I am a bit reluctant to answer your question because cost can be significantly more at Sloan Kettering or Johns Hopkins and maybe less at the Cleveland Clinic. I do not know and as I say there are many factors. Having pegs installed for teeth prosthetics added to the cost.
There are not many hospitals that do this surgery. There are not a lot of doctors that have done this more than a handful of times however Mayo has done well over a thousand and has helped refine the techniques used by others today. If your doctor is using a manual to do this you might reconsider where you are going. Make sure to ask about experience prior to signing the surgery waiver. If the surgeon is offended then you are definitely in the wrong place.
