Answer :
Final answer:
The technician uses wax for the try-in appointment of a denture. After adjustments, teeth are finalized in either acrylic or porcelain.
Explanation:
The material used by a laboratory technician for the try-in appointment of a denture is usually wax. This wax is used to arrange the denture teeth for a preliminary examination before finalizing in acrylic. It's during this stage that any necessary aesthetic and functional adjustments are made.
Once satisfactory alignment is achieved, dentition is set in a more permanent material, often either acrylic or porcelain. However, this isn't the stage yet for materials such as amalgams, which contain silver and other metals. These are typically used for fillings, not dentures.
