 Hi neal and tim,
I think it's a CAD/CAM system named Cerec which was developed by siemens in
germany, You can visit the page

or http://www.getset.com/mmi/cadcam.html

RDGS
Yours yang

During my time in Europe a few years ago, I made
contact to a company in northern Germany with
the name MicroDenta (or similar). Unfortunately,
a quick look through my cardfile does not reveal
a card. In any case, these guys developed an
optical based scanner that fit in the mouth and
provided point cloud data with +/- 1 micron
accuracy. They directly interfaced the data to
a milling device to produce crowns. I've heard
of other groups doing similar things here in the
US, but do not know specifics. You try contacting
Prof. Joel Barlow at UT-Austin 512 471 1271. He
was doing some work in this area and may be able
to point you in another direction. He may also
have information for the contact I mentioned
above as I forwarded it to him for this purpose.

Ciao.
Neal
