Question:
From what I have read, the crown procedure involves 2 sittings with
the dentist becuase the crown needs to be fabricated in a lab. My
dentist tells me that she will do a post and crown procedure in a
single long sitting. How? Is she just trying to rip me off or can this
actually be done. Doesn't the crown need to be manufactured in a lab.
Would appreciate any information before I risk whatever is remaining
of my molar teeth and $1,000.
Answer:
With a Cerec machine or an "in-house" lab using composite materials, a
crown can be made and cemented in one day.
I have no personal experience with either.
I wish my Newsgroup Server would let me post images to this group. I would
show you the images of the Cerec I just finished 20 minutes ago. It was too
wide to be a "normal" posterior resin restoration, too wide to be an inlay.
Yet, not enough tooth involvement to feel good about reducing the entire
thing for a crown. A Cerec restoration is perfect for this situation.

Always seek the opinion of a licensed dental professional before acting on
the advice or opinion expressed here. Only a dentist who has examined you
in person can diagnose your problems and make decisions which will effect
your health.
If you can drop the resolution to simple JPEG images, and email them to me.
I can try posting them for you. If I can't someone else might be able to.
I am supposed to have 5 meg of personal web space somewhere. Perhaps it is
time I learned how to access it. Then I could just post a link.
I understand you point of view and have no problem with it.
That does not mean I will not wish to debate this issue further from time to
time.
I see it as a block of porcelain with better material characteristics than
laboratory fired porcelain. Since marginal accuracy is level with
laboratory porcelain, I feel very good about seating these. I think the big
question to be answered by the future, is whether the bond strength to
porcelain and to tooth is strong enough to support thin/weak cusps, or will
they all need to be "hooded". So far, the bond strength has impressed me
very well.
