What dental material does the laboratory technician use to set the teeth for the try-in appointment for dentures?

  1. Silicone

  2. Wax

  3. Composite

  4. Acrylic

The correct answer is: Wax

During a try-in appointment for dentures, the laboratory technician will use wax to set the teeth before they are permanently secured in the denture base. Silicone is not a suitable option as it is not strong enough to hold the teeth in place. Composite is also not used in this step as it is typically used for dental fillings, not setting teeth in dentures. Acrylic is used to create the denture base, not set the teeth. Ultimately, wax is the most appropriate option for this procedure.
