What term describes the process taken to make a model of your teeth?

• A. Extraoral Photograph
• B. Impressions
• C. Panoramic X-Ray
• D. Archform

Answer: (B)

Taking an impression is the process used to make a model of the teeth. This involves placing a pliable material in a tray and seating it against the teeth and surrounding tissues to capture the exact shape and relationships. When this negative mold is poured with dental stone or plaster, it yields a positive study model that clinicians use for diagnosis, treatment planning, and fabricating appliances or restorations. The other terms describe different things: an extraoral photograph records facial and dental appearance outside the mouth, a panoramic X-ray provides a single radiographic image of the jaws, and archform refers to the overall shape of the dental arch, not the mold-making process.
