Question

Quizplus · Accepted Answer

Custom impression trays can be made from resin in addition to other materials, such as acrylic or metal. Therefore, option B is the correct choice. Options A, C, and D are incorrect. Custom impression trays are made before the dentist prepares the teeth (option A is incorrect), and they can be either full-arch or partial-arch trays (option C is incorrect). Adhesives may still be necessary to ensure an accurate impression, even if the tray has a smooth surface (option D is incorrect).
