Investing
Investing is carried out with either IPS PressVEST or IPS Empress Esthetic Speed. The corresponding
IPS Silicone Ring with matching ring gauge is used for that purpose.
Please refer to the Instructions for Use of the corresponding investment material regarding the detailed
processing parameters. The following procedure is recommended:
– Do not apply a debubblizer to the wax objects.
– Mix investment material. The investment material contains quartz powder. Therefore, the inhalation of
dust must be avoided.
– Use a suitable instrument for the fine investment of the cavity. Make sure that the delicate wax
margins are not damaged.
– Carefully position the IPS Silicone Ring on the investment ring base without damaging the wax
objects. The IPS Silicone Ring must sit flush on the investment ring base.
– Subsequently, carefully fill the investment ring with investment material up to the marking and posi-
tion the ring gauge with a hinged movement.
– Allow the investment material to set without manipulating the investment ring.
– Do not use IPS PressVEST for investment over the weekend to prevent crystallization.
