How accurate
is the fit of PROCERAŽ restorations?
Since the manufacturing process involves CADD (computer
aided dental design), we are able to achieve a fit of
about 50-60 microns. Based on inquiries to major dental
universities, a 100 micron fit is an acceptable fit for
fixed restorations. The system also builds in a 50 micron
cement space, making the coping fit very passively, but
very accurately at the marginal area.

Is this product suitable
for patients who have bruxing problems?
It is the opinion of many researchers that there is
no material that is absolutely suited for bruxing patients.
Patients who brux will wear resin materials just as
quickly or faster than they wear their own enamel. Typical
feldspathic porcelain will not wear but may chip or
crack under heavy loading. Most clinicians tell us a
splint night guard or bruxing appliance, such as our
Crystal Clear biteguards, is the treatment of choice
for bruxing patients. PROCERAŽ porcelain may provide
more comfort since it is softer than typical porcelains
and certainly will not wear like the particle filled
resins.
What if I have to cut one of these
restorations off? Is this difficult?
Yes. The core is made of a very hard material. Use a
diamond with good irrigation.
I understand the copings are manufactured
in Sweden. Does Keller send my impression and cast all
the way to Sweden? How long do I have to wait for the
finished restoration?
The process involves mapping your dies into the computer
with a very sophisticated digitizing instrument. The
data gathered during this mapping procedure is the only
information/material sent to Sweden via modem. In Sweden,
the Nobel Biocare technicians replicate your die exactly
using the data we sent. The coping is fabricated and
shipped to Keller. We then apply the veneering porcelain
according to your prescription using the original model.
Overall turnaround time is 10 lab days.
What insurance code
should I use for PROCERAŽ?
ADA Code - 02740
What is the cost of a PROCERAŽ
restoration?
We have priced PROCERAŽ comparable to our other
all-ceramic crowns. As a dental clinician, you should
save chairside time since the preparation and cementing
procedures are less demanding than other all-ceramic
alternatives.
