What material is typically used to create porcelain-fused-to-gold crowns?

1. Only gold

2. Only porcelain

3. Metal and fused porcelain

4. Composite resin

The correct answer is: Metal and fused porcelain

Porcelain-fused-to-gold crowns are designed to combine the strength and durability of metal with the aesthetic appeal of porcelain. The correct choice indicates that this type of crown incorporates both metal and fused porcelain. The metal base, typically made from gold or a gold alloy, provides a robust foundation that withstands the forces of chewing and biting. The porcelain layer is then fused to this metal, offering a natural tooth-like appearance that is essential for visible areas in the mouth. This combination allows for a restoration that not only performs well functionally but also blends in aesthetically with the surrounding teeth. The other options do not capture the dual-material nature of these crowns. For instance, stating only gold or only porcelain overlooks the critical aspect of how both materials work together to create a successful dental restoration. Additionally, composite resin is not used in porcelain-fused-to-gold crowns, making it an inappropriate choice for this specific type of crown.
