do you mean the new lab manufactured degussa cercon system?
If so I have made 6 bridges in the system over a 4 month period I have
layered them with Jeneric Pentron 3G ceramic - all are still intact
HOWEVER....I am bit of a fit fanatcic (checked under mantis 6X
magnification)and they were all FAR from the fit I can achieve with a
pfm or pressed ceramic. I do not have the scanning/manufacture system
my self so I sent these to other labs to do the framework - in all
they were sent to 3 different labs - the fit was not good from any.
conclusion - the fit would be acceptable for many, but if you want the
very best I do not believe that this system can currently offer
superior fit OR the people using the system need more experience.
Interestingly on my third lab I said that I was unhappy with the fit
from the other 2 - he ssured me that it was technician skill and that
he could get a perfect fit.....his was the worst...just goes to show
how subjective our craft can be!
Hope this helps,
