cutbacks and layering in order to get the restoration into the zone
of “realistic” for me (Figs. 8-9). In my opinion, lithium disilicate is
one of themost promising esthetic, enduring and versatile indirect
materials available to clinicians today.
The following cases are briefly presented, not with the intent
to describe technique, but with the purpose of visually demon-
strating the versatility and the potential esthetic quality of CAD/
CAM e.max material in a variety of case types.
CASE STUDY 1 — DURABILITY:
SIX OR MORE ANTERIOR INDIRECT RESTORATIONS
USING E.MAX CAD
In this case (Figs. 10-11), indirect restorations were designed on
teeth #4-14 using chairside CAD/CAM (CEREC) and lithium
disilicate. The front teeth overall had a good underlying color,
which allowed for the restorations to be thin (progressing from
0.3 mm at the gingival third to 0.7 mm in the incisal third). Thin
monolithic restorations with e.max lend to conservative prepara-
tions, enamel bonding on the facials and a natural, esthetic look
because the underlying tooth color is allowed to filter through the
translucent material and naturally modify the visual optics of the
case (Figs. 12-13). All restorations were milled from an e.max high-
translucency B1 ingot.
When an anterior restorative case presents with acceptable under-
lying tooth color and the potential for thin restorations, e.max can
offer the clinician confidence in knowing that the material selected
can deliver strength, durability and a naturally beautiful look.
CASE STUDY 2 — VERSATILITY:
COMBINATION ANTERIOR INDIRECT RESTORATIONS
WITH THE USE OF E.MAX CAD
In this case (Figs. 14-15), two indirect restorations were designed
for the maxillary central incisors using CAD/CAM (CEREC) and
lithium disilicate. Tooth #9 was found to be non-restorable due to
