What term is used to make molds of patient arches for replication in gypsum?

• A. Gypsums
• B. Replacement Denture
• C. Impression Materials
• D. Immediate Denture

Answer: (C)

Impression materials are used to capture the shape of a patient’s arches so a precise replica can be made in gypsum. They are chosen for their ability to flow and record fine details of teeth and soft tissues, then set so the impression can be removed without distortion. After taking the impression, gypsum products like dental plaster or stone are poured into it to create the cast. The other options refer to the cast material or to types of dentures, not the mold-making medium.
