CASE STUDY 3 — ESTHETICS:
RESTORING A SINGLE CENTRAL INCISOR
The two cases highlighted here demonstrate how the properties of
e.max CAD have the ability to closely mimic nature. The first case
(Figs. 18-19) illustrates the comparably enamel-like characteristics
of e.max using a thin veneer to restore a single central incisor #9.
A high-translucency BL2 ingot was used.
Examining the second case at an increasedmagnified view (Figs.
20-21), the material can more easily be compared to the adjacent
natural tooth. Tooth #9 is an e.max crown milled from the same
HT BL2 ingot. No “cut-back” technique was applied here. The
way that the light transmits through and responds to this mono-
lithic ceramic — especially in the incisal half where enamel is
being replaced — innately gives the restoration a very “realistic”
and predictably natural look.
CONCLUSION
There continues to be an increasing number of new materials
on the market geared toward CAD/CAM indirect dental resto-
rations, and there are likely advantages to be found in each of
them. However, from a clinician’s perspective, it will generally
come down to predictability. Clinicians want a material that will
hold up well over time, one that they can utilize in a variety of
indirect restorative solutions that they offer to their patients,
and one that innately has the optical properties to look virtu-
ally undetectable alongside the natural dentition. In light of
the rapid pace of advancements in dental materials, the current
advantage of finding the combination of durability, versatility
and esthetics in a single material may long be referred to as “the
e.max advantage.”
