Which term is a soft, yellow, corrosion-resistant metal used in the making of indirect restorations?

• A. Gold
• B. Ceramic
• C. Filler
• D. Esthetic

Answer: (A)

Gold is used for indirect restorations because it’s a soft, yellow metal that resists corrosion and can be cast and finished to a very precise fit. Its malleability allows the material to be shaped and polished to seal well with the tooth, while its wear resistance and biocompatibility contribute to durability and safety in the mouth. Ceramics are non-metals used for esthetic crowns, not metals. Filler and esthetic refer to general terms rather than a material, so they don’t describe what’s used for these metal restorations.
