Indications
– Fully anatomical pressing on masked (opaquerized) crown and
bridge metal frameworks
– Pressing on dental alloys with a CTE range of 13.8–14.5 x 10 -6 /K
(25–500°C) with a silver content of <10%
contraindications
– Pressing on dental alloys with a CTE outside the stipulated range
and not featuring the defined composition
– Alloys with a silver (Ag) content higher than 10%.
– If patients are known to be allergic to any of the ingredients, the
material should not be used.
– Pressing on titanium and zirconium oxide frameworks
– Very deep sub-gingival preparations
– Patients with substantially reduced residual dentition
– Bruxism
– Any other use not listed in the indications
Important processing restrictions
– Exceeding or falling short of the stipulated layer thicknesses for
press ceramics
– Failure to observe the layer thickness ratio between the framework
and layering ceramics
– Failure to observe the necessary minimum connector and frame-
work thicknesses
– Layering with IPS InLine One / IPS InLine layering materials (e.g.
Dentcisal, Dentin, Incisal, Deep Dentin, Margin, Impulse and
Gingiva materials, etc.)
– Mixing with and processing in conjunction with other dental
ceramics
– Pressing over dental alloys not within the stipulated CTE range
Side effects
If patients are known to be allergic to any of the components in the
materials, IPS InLine PoM restorations should not be used.
Material
The IPS InLine PoM ingots are made of a glass-ceramic material
containing leucite and based on synthetic glass raw materials, which
contain small quantities of an opalescent glass-ceramic in addition to
the translucent components. This provides the ingots pressed to full
contour with their highly esthetic appearance. The ingots are shaded
with pigments, the temperature resistance of which permits the high
shade match of the pressed restorations. Both in their pressed and
unpressed condition, the ingots demonstrate an iso-tropic structure,
which is responsible for its homogeneous distribution of the leucite
crystals and the high strength. Another important feature of
IPS InLine PoM is its excellent firing stability, which enables the
application of Touch-Up materials, Shade, Stains and Glaze without
jeopardizing the accuracy of fit of the restoration. The Touch-Up
materials are leucite glass-ceramics shaded according to the ingot
shade concept. Their thermal expansion and firing temperature are
adjusted to suit the application in the cervical area of the ingot after
pressing and before the characterization firing cycles.
