Having worked at a dental implant startup in Vienna ( http://www.bioimplant.at/ ), I've experienced first-hand the obstacles that prevent new treatments and technology from reaching the patient. In summary: here is an 'immediate' dental implant requiring no drilling or bone augmentation (ie. surgery-free), that can be placed in minutes, and - once healed in - has no risk of future infection (peri-implantitis).

Some people turn out to be allergic to titanium. Zirconia is the best choice in such cases. (Zirconia is arguably the most biocompatible of all implant materials.)
There's a lot of medical literature about ceramic implants, but you can be assured that it's definitely at least on a par with titanium implants.
