Implant treatment normally runs into the tens of thousands of dollars. That price is why most people who need it never get it.
The Institute is not a typical dental office. It is a post graduate training campus where licensed dentists from around the country come to build their skills in full mouth implant technique and advanced restorative work. Those doctors pay tuition to train here, and they perform surgery under the direct supervision of senior faculty.
Their tuition offsets the surgical cost. So your extractions, your bone grafting, and your implant placement are covered by the program. What you pay for is the restorative portion: the crowns, bridges, or dentures that finish the case.
Everyone gets something out of it. The doctors get real cases under expert supervision. You get implant treatment you could not otherwise reach.
