Which term best describes the material used to take impressions of the mouth for denture fabrication?

• A. Gypsums
• B. 5-7 years
• C. Rebase
• D. Impression Materials

Answer: (D)

Impression materials are the substances used to capture an accurate negative imprint of the mouth for denture fabrication. They must reproduce fine details, stay dimensionally stable as they set and during storage, and be safe and comfortable in the mouth. This makes them the correct term because the question asks for what describes the material used to take impressions. Gypsum is used to pour impressions to create casts, not to take the impressions themselves. Rebase refers to modifying the denture base, not the impression material. The age range option is unrelated to impression materials.
