if you're still in Boston, you should definitely schedule a consult with Dr. Leonard Kaban
thanks man, I'll hopefully be back in Boston sometime late spring summer to defend my thesis finally, so thanks for the suggestion! I also wanted to post this --he's one of the pioneers regarding distraction and WOW he can do a lot of amazing stuff. By the way, if you or anyone else has not yet had extractions of bicuspids(look it up if you don't know what I'm talking about) DON'T HAVE IT DONE(or at least get like 5 other opinions from surgeons and orthos).
Regardless, this quite clearly shows the lower jaw can be distracted width wise, lengthwise, as well as upper and all sorts of stuff. I'd browse the site a bit --and also this place looks like a real centre for this tye of thing which is really imp. because it would have designed protocols and a lot of experience instead of a doc who is just doing distraction on his own somewhere.
Also, I wonder since it's in Venezuela if the prices are better than North America.
It would be GREAT to talk to some patients who have visited this place/doctor and more examples.
