Again, dentures on implants aren't equal in cost :)for single implant surgery you have to pay about $1K. Single point ( crown ) made on such implant costs additional $400-$600. So let us have 6 implants in upper jaw and a 14 point bridge ( that means 14 teeth ), it gives us about $12K. Including lower jaw (mandible) it's about $24K then.

Here's a picture of what I'm talking about

Picture isn't mine though :)
