•
Apply the scanning powder and scan
the restoration.
•
Rinse the powder off with an air-water
spray. If any powder remains, it may be
removed with a cotton pellet soaked
with Surpass 1, rinsed and dried.
Step 3: Remove the oxygen-inhibited layer
with isopropyl alcohol.
Step 4: Apply imaging powder.
•
Isolation may be removed at this time,
or it may be left in place, depending on
clinician choice.
•
Once the restoration is fabricated and
cleaned, the inner bonded surface
may be sandblasted lightly with 27
micron aluminum oxide, rinsed and
dried. Then Interface and Surpass 2 are
applied and light-cured.
•
If isolation has been maintained,
Surpass 2 only need be applied to the
sealed prep, dried and light-cured. If
isolation has not been maintained, the
sealed prep should be cleaned with a
cotton pellet soaked in alcohol, rinsed
and dried. Then Surpass 2 may be
applied as above.
•
Anchor luting cement is then inserted
either into the prep or onto the fitting
surface of the restoration, and the resto-
ration is seated. As the Anchor resin
gels, the excess may be removed. Once
the excess cement is removed, each
restoration surface is light-activated for
10
seconds and the process is complete.
KEY TAKEAWAYS
When delivering a restoration, all
surfaces must be clean prior to starting
the bonding protocol. The following steps
will ensure proper bonding:
•
Steam-clean the restoration as soon as
it exits the milling unit. The lubricant
is a heavy machine oil that is difficult to
remove. Donot dependona simple rinse,
and never short-change the importance
of this step.
•
Seal the tooth prior to imaging. Using
Surpass Self-Etch adhesive system, seal
the tooth immediately after prepara-
tion to eliminate any contamination
that could lead to debonds or sensitivity
in the final restoration. Never allow
imaging powder to come in contact
with the tooth surface to be bonded.
These two concepts are vital and
will ensure a successful and consistent
delivery of every CAD/CAM restoration
done in your office.

Step 5: Remove the imaging powder with
isopropyl alcohol.
Step 6: Apply one coat of Surpass 2, dry
and light activate.
Step 7: Cement in place with Anchor.
Step 8: Sit back and admire a perfect
delivery.
