TWO PART MOLD - Use Mold Release Spray
8-1x4 structures for upper and lower, in wax or cold cure acrylic: small, medium, large, extra large. #8 Cusps Mold can be overlaid on occlusal of frame if metal occlusal is desired.
This new design will save more than 50% of pontic substructure weight, whether it be for gold, semiprecious, or non-precious metal. This unique design maintains and improves substructure strength, and at the same time provides the covering material (porcelain or acrylic) with a lively translucent appearance that is not evident with a solid understructure widely used today.
