CEREC CLINICAL APPLICATION
Responders were queried on their
application of the CEREC system for a
number of clinical treatment options.
These included:
• When planning a full crown restoration
for a posterior tooth, you aremore likely
to do a lab-fabricated zirconia crown,
gold crown, PFM crown, CEREC
crown, or other crown not listed.
• When planning a full crown restoration
for ananterior tooth, youaremore likely
to do a lab-fabricated zirconia crown,
gold crown, PFM crown, CEREC
crown, or other crown not listed.
• When planning to replace one cusp on
a posterior tooth, you are more likely
to use an amalgam, direct posterior
composite, cast gold, CEREC restora-
tion, other restoration not listed.
• When planning to replace multiple
cusps on a posterior tooth, you are
more likely to use an amalgam, direct
posterior composite, cast gold, CEREC
restoration, other restorationnot listed.
Figures 4-6 show the most common
techniques the 256 responding dentists
would used to treat the specific clinical
situations based upon clinical setting.
Dentists in private practice were
more likely to choose the CEREC
system to fabricate crowns for both
anterior and posterior teeth compared
to lab-fabricated crowns. This treat-
ment choice again demonstrates a
selection bias of this particular subset
of private practitioners, and this is most
likely attributed to the investment the
private practice dentist has made in the
CEREC system. The private-practice
dentists that responded to the survey
would have selected the CEREC crown
93 percent of the time for posterior
teeth, and 73 percent of the time for
anterior teeth.
The greater percentage of posterior
crowns may well be a reflection of the
increased esthetic demands that are
generally required for anterior crowns,
and that many private-practice dentists
still rely on laboratory technicians to
meet the expectations of these more
esthetically challenging restorations.
This is also evident when private-
practice dentists were asked their
preferred technique for placing ante-
rior veneers. Only 47 percent of the time
did private practice dentists indicate
they would complete the veneers with
the CEREC system in a single appoint-
ment, with an additional 18 percent
indicating they would complete one or
two veneers with the CEREC system in
two appointments. When asked about
their preferred technique for three
or more anterior crowns or veneers,
only 12 percent indicated they would
complete the restorations at the same
appointment with an additional 11
percent indicating theywould complete
three or more anterior restorations on
the same day. Also, 32 percent of the
private practice dentists indicated they
would complete the anterior restora-
tions at a second appointment using
the CEREC system. And, 45 percent
