How many implants do you think you see in the last 2 pages? I think I see one set.
And BTW, plastic surgery is a great example of the free market at work. Implant costs have dropped by a large percentage and results are much better than in the past. Same as for laser eye surgery. Better results, much cheaper than it used to be.
Other health care that is covered by insurance/government - much more expensive and your results may vary.
