that can be fabricated chairside and
adhesively bonded into place using a
simplified adhesive system (Multilink
Automix). Multilink Automix achieves
the fast high bond strengths required for
today’s highly esthetic, metal-free resto-
rations according to an efficient and
effective adhesive protocol that simulta-
neously enables easy clean up.
6.
After milling in the CERECMC XL,
the restoration was tried in and the
shape refined, after which it was
glazed and crystallized.
7.
To initiate the adhesive protocol,
the restoration was etched for
20 seconds using red IPS Ceramic
Etching Gel (Fig. 14).
8.
Monobond Plus silane was then
applied to the bonding surface
of the restoration and allowed to
react for 60 seconds (Fig. 15) and
air-dried.
9.
A 1:1 ratio of the Multilink A & B
Primer was mixed, after which
one coat was applied to the tooth
structure by scrubbing it into the
preparation for a total of 30 seconds,
starting with the enamel, and then
completely air dried.
10.
Multilink Automix adhesive was
then placed in the restoration
(Fig. 16) and seated.
11.
Excess adhesive was removed with
a paint brush, and the restoration
was tack cured using the quarter
technique, curing for one to two
seconds.
12.
Additional excess was removed
with floss, and the restoration
received a final full cure.
13.
Remaining excess adhesive was
removed with a Cavitron and the
occlusion verified (Figs. 17-19).
CONCLUSION
Although lateral restorations require
high esthetics, they also necessitate
strength, functionality and durability.
Therefore, when treating patients
whose teeth in these areas demonstrate
deficiencies, clinicians are tasked with
designing restorations and adhesively
bonding them in a manner that will be
esthetically pleasing but also predictable
and long lasting. Lithium disilicate (IPS
e.max CAD) enables dentists to provide
high-strength, esthetic restorations
