Glidewell is in California as far as I know...
When Cerec was just getting started, I thought they proposed just that - to
have the milling machine at the lab and the doctors would scan the preps and
modem the data into the lab. You are saying they scan the prep on the model
and mill it from that?

Of course we can. anyone with a CEREC machine can do that. Just spray
powder on the model, scan, design and mill. About once a year, I will get a
case on a second or third molar that is a lone standing tooth and is tipped
mesially. The patient wants the tooth restored, but is not interested in
uprighting, implants, etc. In order to postion the camera lens parallel to
the occlusal surface, I have to pour models, grind off the mesial teeth, and
scan in my lab. No way to position the camera properly in the mouth for
these teeth. Some dentists were working off models when doing the six
anterior teeth since we used to onlyl be able to postion the camera from the
mesial. In order to get right and left teeth on one virtual 3D model, we
would have had to bring the camera from the distal on one side. Since most
patients do not come with zippers on their cheeks, they would work off
models. The latest software release (this past month) now allows us to
image both sides from the mesial and simply invert one set of images to get
both sides on one virtual model without pouring a model. Great for veneer
cases.

Pretty cool and thanks for the offer to mill the inlay...I just took the
impression and since it was all supragingival - -no cord, no waiting for
hemostasis, no build-up...much time saved, same fee as full coverage too..

Then, when you read the studies and see that these have the same failure
rates as FGC and gold inlays?????? You wonder why everyone is not doing
these. BTW, the studies showed machine milled onlays to have much better
survival rates than laboratory fired ones. Has to do with consistency of
material properties.

I'll see how this one goes...I may be doing more if this one is to my
liking. I chose an onlay because this is a cusp replacement on a 16 yo. I
felt composite would not last long enough and I don't place amalgam any
more. I didn't want to prep the whole tooth down for full coverage so there
you go....onlay city.

What's 'long enough'? I've got lots of composites in the 15-20 year
range as I type (some are cusp build ups too).

The Onlay I have milling right now replaces the DL cusp of #15 with a
partial wrap around DL and ML. 70% of the ML cusp and 85% of both lingual
cusps remain intact. I would hate to cut away all that solid tooth to make
a full coverage crown. 16.8 minutes of mill time. (Would have been about
10 minutes, but I forgot to click the "rapid milling" icon. (New with the
latest software).
