Hi, Christine,
	In response to your query about the difference between Technovit
7100 and 7200 - No, they are not the same.  Kulzer makes a bunch of
Technovit resins - even has one for repair of horse hooves!  The Technovit
7200 is a proprietary, light curing resin that is specifically designed for
bone/implant procedures.  It is a very brittle monomer.  The Technovit 7100
is a heat curing, glycol methacrylate resin and is much softer and more
elastic.  It is really not strong enough to support undecalcified bone with
implant.
	However, there are also many procedures for embedding bone/implant
with methyl methacrylate.  "Biotechnic and Histochemistry" and "The Journal
of Histotechnology" are two magazines filled with excellent articles on the
subject.   Look for articles by Callis, Sanderson, or Sterchi.  Those three
have been prolific writers on the subject.
	The National Society for Histotechnology (NSH) has a committe
called the Hard Tissue Committee (HTC) comprised of  many people dealing
with the exact procedures you are concerned with.  If you would like to
know more about the HTC,   please email me and I will send additional info.
	Best Wishes,
	Linda
