Ripped Toenail?...When will it grow back?

Back in March my toenail busted. It was pretty gruesome and ugly. There was dried blood on it and everything. I put ice and elevated it to make the swelling go down. Then a few weeks later, after the accident, the nail started to tear off, and so I clipped it off to the nub. The root is still there and now its not completely grown back, about how long would it take to make it finish growing. Its been growing back since the beginning of May maybe even before. Now it's 3/4's of the way back, about how much longer should it take to make it come back all the way?
