Dr. Pham is an Oral and Maxillofacial Surgeon teaching and practicing at
the University of Montreal. I don't remember his first name, but I'll
try to find out. If you Google on "Pham" + "Wisdom Tooth Removal" you
may hit some articles he's done on this subject. He taught us this
procedure in a Continuing Ed course a while back, and judging from the
number of questions he fielded on it, it is not well known.

That is what is hoped (best-case scenario), yes. The idea is to totally
remove the crown right down to the roots and then close. I don't
remember if he puts any sedative dressing on the exposed nerve tissue in
the root fragments, but I don't think so. Obviously, there are also
risks of infection and abscess/granuloma/cyst formation when one leaves
root fragments in the sockets. However, if your OMFS has done a few of
these and has had success, I'd give it serious consideration.

If we're lucky, one or both of the OMFS's that haunt this castle will
give you the benefit of their experiences.
