Indirect
vs. Direct
Restorations
One option is easier, the other faster-
which makes the most sense for you?
by Richard Rosenblatt, DDS
Dr. Richard Rosenblatt owns a
practice in Lake Forest, Illinois,
focusing on CAD/CAM and digital
dentistry. In 2005, he founded
the Northern Illinois Cerec Study
Club, one of the largest of its
kind worldwide. Rosenblatt
moderates the Cerec forum on
Dentaltown.com, and is on the
faculty of Cerecdoctors.com and
in the CAD/CAM division of Spear Education. He is a basic
trainer for Patterson Dental, has been a software alpha and
beta tester for Sirona Dental Systems, and has lectured
internationally regarding CAD/CAM and digital dentistry.
In cases where the dentist has to make a judgment call between
a direct resin restoration and an indirect Cerec restoration, there
are a number of factors to weigh, including the demands that will
be placed on the area, timing of the procedure, aesthetics of the
available materials, and what will serve the patient best overall.
In many cases, an argument can still be made for either method
even after taking these things into account. But if you're like me,
you may find yourself leaning toward using CAD/CAM to create
an indirect restoration.
This choice is made easier by the availability of milling materials that are resinlike in many respects. The case shared here will
illustrate the use of a resin nanoceramic that performs much like
a composite restorative. This makes it easy to adjust-something
that might sway dentists in their choice between the two treatment
options. While a direct restoration on an occlusal surface requires
considerable time to sculpt and contour, using the Cerec system to
design an easy-to-adjust indirect restoration is much simpler for many
dentists. Furthermore, the use of an indirect material eliminates
worries about polymerization shrinkage and ensures consistency
throughout the restoration.
Marginal fit is another strong benefit of the material used here.
While direct resins can often have inconsistent and rough contacts
that can be felt while flossing, this milling material results in
excellent-fitting margins and gives the dentist more control over the
contacts. The resin component of the material makes it less brittle
and enables excellent edge quality.
