Expansion control

Note:

• For premolar and anterior crowns, attention has to be paid to the fact that the higher expansion value will result in enhanced fit of thin and small-sized preparations.
• Expansion values given above are reference values. Deviations from this are possible, due to different preparation templates, preheating furnaces, press temperatures, etc.
• When using acrylics, the expansion may deviate from the table above.

Please note:

• Use a total of 23 ml of liquid for 100 g of powder.
• Use a total of 46 ml of liquid for 200 g of powder.

Note:

• Detailed information on the processing of the investment material can be found in the VITA AMBRIA INVEST Instructions for use 920-02800.

Demoulding

Note:

• Remove the investment base with a turning movement.

• Carefully remove defects from the bottom of the investment ring using a plaster knife.

• Ensure an upright position (90° angle).

• Press the investment carefully out of the silicon ring.
• Break the edges of the investment without allowing investment material to fall into the channel.
