Final answer:
A prescription from the dentist is required before a lab technician can make an appliance.
Step-by-step explanation:
A prescription from the dentist is required before a lab technician can make an appliance.
In the context of dentistry, when a patient requires a dental appliance such as dentures, braces, or a mouthguard, a prescription from the dentist is necessary. The prescription outlines the specific details and requirements for the appliance, including measurements and specifications. This ensures that the lab technician can create the appliance accurately and tailored to the patient's needs.
For example, if a patient needs a set of dentures, the dentist would write a prescription specifying the size, shape, and color of the dentures. The prescription serves as a guide for the lab technician, who uses it to fabricate the dentures according to the patient's unique oral structure.
