Product description

The IPS Investment Ring System 300g represents the latest
investment ring generation for the PRESS technology. It can be
used for pressing on long-span frameworks, as well as for the
pressing on several smaller restorations in one working step.
The Investment Ring System is ideally compatible with existing
Ivoclar Vivadent press ingots and press furnaces.
Indications
– IPS e.max ZirPress
• Pressing on zirconium oxide frameworks up to a bridge
span width of 10 units (depending on the dimensions of
the dental arch)
• Pressing on several smaller zirconium oxide frameworks
– IPS Inline PoM
• Pressing on frameworks fabricated of a ceramic alloy up
to a bridge span width of 10 units (depending on the
dimensions of the dental arch)
• Pressing on several smaller frameworks fabricated of a
ceramic alloy
Limitations of use
– Casting of alloys
– All applications not explicitly approved as an indication

Instructions for Use
Sprueing
Always attach the sprues in the direction of flow of the ceramic
and at the thickest part of the wax-up so that smooth flowing
of the viscous ceramic during pressing is enabled.
We recommend the following procedure to determine the
accurate wax weight:
2
– Weigh the framework (with the fired liner/opaquer).
– Weigh the IPS ring base 300 g (seal the opening of the
ring base with wax).
– Position the contoured restoration on the ring base and
attach it with wax. Weigh again.
– The wax weight of the contoured restoration is calculated
by deducting the weight of the ring base and the weight
of the framework from the total wax weight.
