IPS d.SIGN Deep Dentin
In order to achieve true-to-nature shade effects
in areas where space is limited, IPS d.SIGN
Deep Dentin materials are used. They are
directly applied on the opaquer layer. For
pontics and crowns margins thinning
towards the metal, Deep Dentin material of
the appropriate tooth shade is applied in the
cervical or basal area to enhance the shade.
1 st dentin and incisal firing
Before layering the Dentin and Incisal materials, sealing the
model is a very important step. In this way, the ceramic
material is prevented from drying out or sticking to the
model. Use the IPS Model Sealer and the IPS Ceramic
Separating Liquid to seal and lubricate the gypsum die and
the adjoining areas of the model.
Deep Dentin layering to enhance the shade in the cervical area.
Use the IPS Model Sealer and the IPS Ceramic Separating Liquid to seal and lubricate the gypsum die and
the adjoining areas of the model.
The recommended drying times depend on how
much moisture was absorbed by the ceramic and
on whether or not the restorations was predried.
To achieve an optimum bond between the ceramic materials
and the opaquer surface, apply the ceramic material in small
increments, particularly in the cervical and interdental areas
(for bridges) and slightly roughen it. In this way, the adaption
of the Deep Dentin or Dentin materials on the opaquer
surface is enhanced.
Five different IPS d.SIGN build-up liquids are available, which
are used according to the individual requirements (see page
18 for a detailed description). Depending on the type of
build-up liquid used, various closing times are possible.
IPS d.SIGN Dentin, Incisal, and Transparent materials
Next, outline the mamelon area with a layer of
Dentin material. Individually. Another option
is to contour the fully anatomical shape of
the tooth. If this procedure is used, the
contoured crown has to be reduced in the
labial, incisal-mesial, and distal areas. The
mamelon shape is, once again, only outlined.
Irrespective of the method used, make sure
to provide adequate space for the
subsequent application of the Incisal and
Transparent materials.
Recommended drying times:
IPS d.SIGN mixed with
Build-Up Liquid Light
approx. 4–5 minutes
Build-Up Liquid Medium approx. 6–7 minutes
Build-Up Liquid Premium approx. 8–9 minutes
Build-Up Liquid Optimum 1 approx. 6–7 minutes
Build-Up Liquid Optimum 2 approx. 6–7 minutes
IPS d.SIGN Essence
IPS d.SIGN Essence ceramic stains
may be added to any IPS d.SIGN
layering materials for
characterization. The mixing ratio
depends on the desired shade
effect of the layering material.
While IPS d.SIGN Stains and Shades are only suitable for
surface characterization, IPS d.SIGN Essence stains may be
used for both intensifying the shade of the layering material
and surface characterization of the fired restoration.
For large restorations, such as bridges and implant super-
structures, the number of corrective firings can be reduced
by conducting a preliminary firing using either Deep Dentin
or dentin material. When using this technique apply the
Deep Dentin or dentin material in areas where maximum
sintering shrinkage is anticipated. Fire this material using
the 1
st dentin and incisal firing parameters.
