How much does a mandibular osteotomy surgery (for tmj and overbite), cost in canada? is is covered on health insurance?

Surgery? Insurance?: I practice in the us and assume it would be a similar procedure in canada. I suggest you explore your situation in this way. Find the dentist\surgeon whom you respect and trust. See and consult a few if necessary. Get some recommendations. Discuss your situation, have them discuss the procedure and fees. You and their office staff can call your insurance company to discuss your coverage.

"Health Canada: Check the canada website and they can give you the best answer, or check with a local dentist and they can give your their understanding as well.

Service: Jaw surgery is a service, not a commodity. Cost of procedure determined by many factors, so you'll have to ask the Oral Surgeon who will be performing the surgery to advise you as to cost. As to insurance coverage, call your insurance provider's hot line for an answer, or ask the Oral Surgeon directly.

Varies: Probably varies by region and surgeon. Ask the oral surgeons in your area.

"Free healthcare" : You pay out of pocket for the surgeons costs, but not the hospital. Total out of pocket cost is around $(CAD)14000 - $(CAD)17 000.
