Dental Laboratory Technician Trainee Practice Test

Waxes are used for creating and shaping the denture base during the wax stage. Baseplate wax forms the mock denture base for trial fitting, set-up wax holds the artificial teeth in their planned positions on that base, and rope wax—a flexible, rope-like wax—helps build and refine border contours. These waxes are favored because they soften with heat for easy shaping and harden when cooled, allowing accurate adjustments before final processing. The other items are not wax materials: denture teeth are the actual teeth components, reversible hydrocolloid is an impression material, and a pressure pot is equipment used in processing.
