What is done to baseplate wax before placement in the patient's mouth for a bite registration?

  1. Chilled

  2. Warmed

  3. Moistened

  4. Coated with a disinfectant

The correct answer is: Warmed

Before placement in the patient's mouth for a bite registration, baseplate wax should be warmed. Other options such as chilling, moistening, or coating with a disinfectant can cause the wax to become too hard, too soft, or alter its properties, making it difficult to accurately record the patient's bite.
