UDLT 104 - Dental Metallurgy
Students will develop enhanced understanding of the Dental Laboratory Technology profession. Including an examination of metals currently used by the dental technician. Includes introduction to dental alloys (e.g. physical and chemical properties); weights, measures, and calculations; metal sensitivities and allergies. Also includes alloy processing; equipment calibration; metal treatment and torch techniques; Laws of Casting; selective laser melt (SLM); electro-polisher and electrolyte solution operation; and safety procedures.
Prerequisite(s): DLT 101 and 102, or concurrent enrollment
