Answer: We make impressions using gypsum, not take impressions. The reason for this is that gypsum is a rigid material that does not have the ability to conform to the soft tissues of the mouth. Instead, we use a flexible impression material, such as alginate or silicone, to take an impression of the teeth and gums. Once the impression is taken, it is then poured with gypsum to create a rigid cast of the teeth and gums. This cast is then used to create dental restorations, such as crowns, bridges, and dentures.
Making signifies that we have to make an effort to record all the landmarks necessary for an impression. That's why its make an impression and not just take one!
