Order a rezloh tooth bar. I ditched my teeth on my Bobcat bucket and went with the rezloh blade. I can grade better and when I am digging rocky areas, I tend to slice more than chip so my materials are smaller. So far, it has held up well. My only complaint is the rezloh is shorter than my teeth were and it is only held on by one bolt versus 2. It comes in 3 pieces, though, and I was told that it wouldn't put too much pressure on the bolts.
It was a lot cheaper than $658 at my dealer and it fits my bobcat 74" C/I bucket
