Cast Partial Dentures

Fabrication of the upper cast partial denture using silicone duplication

Fabrication of the refractory model

Here the setting expansion is clearly visible. The soft silicone material does not restrict this process, instead it curves to accommodate.

After a setting time of 30 min has elapsed, the refractory model can be removed.

The model is placed for a further 30 min into a drying chamber at approx. 100 °C. Adapting the wax pattern is far easier on a completely dry model!
