Fabrication of the upper cast partial denture using silicone duplication

Allow the investment mould to cool to room temperature in order to achieve stress free casting objects.

When under time pressure, allow the investment mould to cool down for at least 30 min in the air and then hold under running water to cool further.

Strike the investment mould carefully with a hammer to remove most of the investment material.

Do not strike the casting button directly with the hammer! This will prevent unnecessary stress in the cast object!

Supercut separating discs are super thin and therefore prevent overheating! High stability due to nylon reinforcement!

Once the casting sprues have been exposed, they can be cut off. The rest of the investment material is then easier to remove.
