Is growing back teeth possible?

Recently I came across an article about growing back teeth in human beings using ultrasound. The article url is here: http://www.tooth-teet...
Is it really possible to grow back teeth or is that still in experimental stages? Has it come to the general dental practice? Some years back due to motorcycle accident I lost my right upper cutting tooth. I am using an implant but it has not been effective.

It would be a good news to me if someone can tell me that I can grow my tooth back.

Thank you in advance for your suggestions.
