How does the dentist convey to the laboratory technician what type of crown is to be made?

  1. Oral Instruction

  2. Email

  3. Laboratory prescription

  4. Phone Call

The correct answer is: Laboratory prescription

The laboratory prescription is the best way for a dentist to convey instructions to the laboratory technician for making a crown. While oral instruction may be used during an in-person conversation, it is not a reliable method as it may be forgotten or misinterpreted. Email is also not the most effective way to communicate specific instructions and details for the crown. Phone calls can lead to miscommunication or important details may be missed. Therefore, a laboratory prescription is the most precise and clear way for a dentist to convey the exact type of crown that is needed.
