In this case, however, TheraCal LC was
used simply as a barrier between the root canal
orifices and the crown buildup material as
well as to increase the bondable surface area.
Clearfil SE by Kuraray, a light-cured self-etch,
was my bonding system of choice because of
its high strength and its sealing properties.
Premier's CompCore AF was injected as
the buildup material and cured. CompCore
AF, which is a dual-cured, fluoride-releasing,
radiopaque composite core buildup material
used in vital and nonvital teeth,2 has been
my core buildup material of choice for years
because it flows well and does not slump.
The material cuts like dentin-smoothly

office to extremely light occlusion to avoid
the two potential issues discussed above.
As a side note, I wish to add that in
my practice, PFMs are used in more than
90 percent of all clinical cases. All my
crowns are inserted with light contacts and
with all lateral interferences resolved. This
alone has eliminated the main drawbacks
of PFMs in my office, and I continue to use

if any wear on opposing teeth and actual
separation of the feldspathic porcelain from
the metal coping is essentially a nonexistent
event in my office.

Qualities of PFM crowns

Prep, crown lengthening
and taking impressions

PFM crowns have two main drawbacks:
1. Their veneer of feldspathic porcelain
causes abrasion, sometimes severe,
of the opposing tooth.
2. They're bilayered restorations, so
there's a chance they will come apart.
Despite the apparent drawbacks to the
PFM, a decision was made to proceed with
its use for one main reason: The opposing
tooth was to be an implant crown, and
implant crowns are always adjusted in my

Attention is fi rst directed to occlusal
reduction with the aid of Premier's Two
Striper football diamond #285.52. The point
of the diamond is always inclined toward the
central fossa to follow the natural contours
of the tooth.
I complete the occlusal preparation with
Premier's Two Striper 240C diamond, which
will provide the laboratory with adequate
central fossa reduction to create proper
