A. Prescription from a dentist
B. Approval from the patient
C. Consent from the insurance company
D. None of the above

Answer :

Final answer:

Before a dental laboratory technician can fabricate a crown, they must receive a prescription from a dentist. This prescription includes specific details needed to create a custom crown for the patient. Approval from the patient or insurance is not the requirement for starting the fabrication process.

Explanation:

The question asks about the preliminary requirement for a dental laboratory technician to begin fabricating a crown. The correct answer is a) Prescription from a dentist. Before a dental laboratory technician can start working on a dental crown, they must first receive a detailed prescription from the dentist. This prescription includes specifications such as the type and size of the crown, the materials to be used, and any particular instructions tailored to the patient's needs. It is essential because it provides the technical details needed to create a crown that fits the patient accurately and addresses their specific dental issue. Approval from the patient or consent from the insurance company, while important in the broader treatment process, are not the direct requirements for the technician to initiate their work.
