Incipient caries generally get either resin or amalgam depending on what the
patient wants. I offer gold, amalgam, resin and ceramic and let the patient
decide. Most often they choose amalgam for price, and resin second. Some
will choose ceramic for these.

I am typically doing Cerec restorations on those teeth which we would
normally place a core and a crown.

I adjust the proximal contact with a HP shank diamond disk. Once the
flossing contact is perfect, I treat the porcelain and bond it to place.
Once bonded, I adjust the occlusion and polish. I prefer to polish in the
mouth so that the margin will become imperceptible no matter where I place
it.

With the 3D software you can control proximal and occlusal contacts on the
screen just as if you were sitting at the bench with articulated models
(except excursive motion checks). You can "wax" it to perfect contacts and
just bond it to place. Often however, once magnified, you will find slight
scratches on the proximal tooth, over-contoured restorations next door, or
tipped teeth. So you build out the proximal contact on the screen and
adjust everything in the mouth to fit the way you want it to be.

Ask WB how much adjustment we needed on those crown we did for Andrew.

Yesterday, a relative was here from out of State. Needed RCT on a molar.
We did RCT and crown with attached post in a bit over two hours complete.
On a plane flying home this morning. It took a little longer since I was
having fun teasing and joking with the patient and my DA. I had to touch
the proximal contacts once with the disk to get perfect flossing pressure,
and touched the occlusion three times with a diamond to get the occlusion I
desired. Polished and was done.

I would say that it took Dr. Steve 10 -15 min to place a Cerec.

That includes proximal contacts, occlusal adjustments, bonding the
restoration (etch, scothbond, flowable, hot Z-100, curing) and
polishing and finishing it. Since he was showing me how he does it,
step by step, it definitely took longer than his usual seating time.
Plus I'm not the best assistant.

I think theres more Cerec than I thought. I appreciate all answers.
But there is only the chair-side Cerec which the people know, right? What is
abaout the lab-side? Is the In-lab not known in the US or only to new?

The lab sytem is available, but other systems are more popular.

No the material is definitely NOT the same. Cerec materials are all
pre-fired in a factory under identical conditions to achieve very specific
material characteristics.

I mill full crown, partial crowns, onlays and inlays from these
pre-fabricated blocks of porcelain using a CAD-CAM machine called the Cerec
Machine.
