Thin Areas
Frequently insufficient dentin/incisal thickness exists (less than
.mm) over the opaque porcelain. The shade in this thin area can
be improved by applying a layer of the opaceous dentin porcelain
under the same dentin porcelain shade. When contouring, you
will be able to reduce the area where the opaceous dentin was
layered and the prescribed shade will be maintained. Complete
the building and firing of the restoration in the normal manner.
Facial Margin (Gingival Color)
If the metal substructure has been designed with a feather
margin, the opaque porcelain around the facial margin leaves
minimal room for the dentin porcelain, and the opaque porcelain
will be highlighted. Esthetics will be improved by applying
opaceous dentin porcelain alone or as a blend with % to %
of one of the opaceous dentin modifiers. This technique creates a
chromatic cervical third, common in natural dentition.
Pontics
A color imbalance frequently occurs between the pontics and the
abutments of a multiple-unit fixed partial denture. The color dif-
ference is caused by the absence of a full metal substructure in
the pontic area. Ceramco opaceous dentin porcelain applied to
the bottom and the cervical area of the pontic creates a uniform
color across the fixed partial denture.
Lingual Fossas and Occlusal Surfaces
Often, inadequate space is available on the lingual surface of an
anterior unit, or on the occlusal surface of a posterior unit.
Ceramco opaceous dentin porcelain applied alone or as a blend
with % to % opaceous dentin modifiers in these thin areas
prevents the opaque porcelain from being highlighted.
APPLICATIONS
T
he Ceramco Opaceous Dentin porcelains are the same hue as the Ceramco dentin
shades, but have approximately % more opacity. They may be used undiluted, or mixed
with the Ceramco dentins or dentin modifiers.
