Final answer:
Bite registration wax is used to form an imprint of the teeth as it can accurately record the relationship between the upper and lower teeth when they come together.
Step-by-step explanation:
The wax that is used to form an imprint of the teeth is B) Bite registration wax. Bite registration wax is designed to record the occlusal surfaces of the teeth to accurately represent how the teeth come together (the bite). This type of wax is soft and pliable upon warming, which makes it suitable for capturing the precise relationship between the upper and lower teeth. The other waxes listed have different dental applications: Dental modeling wax is often used in creating models or mockups; Orthodontic wax is used by patients to cover sharp edges of brackets to prevent irritation in the mouth; and Paraffin wax is rarely used directly in dentistry for dental impressions but may be useful in other medical applications like physical therapy.
