IRT investment ring analysis
The IRT investment ring analysis can be switched on or off.
Setting options: On / Off
The IRT investment ring analysis includes the following functions:
– Automatic recognition of investment ring size
If a preheated investment ring is placed into the furnace, the program for the respective investment
ring size is automatically selected. If the size cannot be defined by the infrared camera or if the size of
the placed investment ring is not available in the selected program, the manual investment ring
selection is automatically opened.
– Check of the investment ring temperature
During the loading process, the IRT system automatically checks if the investment ring has been
preheated according to the instructions. The following situations are possible:
• The investment ring has the correct temperature: This is confirmed with a green check. The
program can be started immediately.
• Investment ring is too hot: After the program start, the note "Waiting for correct investment ring
temperature" is displayed. The furnace waits automatically and the furnace head closes only once the
investment ring has reached the optimum start temperature.
• Investment ring is too cold: In this case, a note is displayed. The heating muffle was not sufficiently
preheated or the transfer time from the preheating furnace to the press furnace was too long. There
is a high risk for an incorrect pressing. Ivoclar Vivadent recommends to sufficiently preheat the
investment ring. After the note has been acknowledged, the press program may still be started.
At the end of the press program, the results panel is
displayed. In the lower area, the temperature of the
investment ring at the time of loading is displayed.
This feature allows the user to coordinate the
preheating furnace with the press furnace:
The investment ring was slightly too cold
at the time of loading. Increase the
temperature of the preheating furnace or
shorten the transfer time. Check the display
again after the next press cycle.
The investment ring was optimally preheated at the time of loading. Preheating furnace,
transfer time and press furnace are optimally coordinated with each other.
The investment ring was slightly too hot at the time of loading. Reduce the temperature of the
preheating furnace. Check the display again after the next press cycle.
If the IRT investment ring analysis is activated, it is recommended to exclusively use original
Ivoclar Vivadent investment ring systems.
