Who is responsible for obtaining intraoral images for computer-aided design (CAD) of milled restorations?

The responsibility for obtaining intraoral images for computer-aided design (CAD) of milled restorations is typically assigned to a Registered Dental Assistant (RDA). This designation indicates that the individual has completed the necessary education and training to perform more complex tasks than those allowed for a Dental Assistant (DA), which requires less formal training. An RDA possesses specific certifications that authorize them to use advanced imaging technologies that are essential for the design and implementation of dental restorations.

While a Dental Assistant may assist with imaging and other supportive procedures, they may not have the requisite training or licensing to perform that specific duty independently and competently. A Registered Dental Hygienist (RDH), on the other hand, focuses primarily on preventive oral health care, including tasks like cleanings and patient education. Their scope of practice does not typically encompass the technical skills required for CAD processes.

In this context, the correct choice underscores the importance of having appropriately trained personnel handle the specialized tasks involved in dental restorations, ensuring both patient safety and the quality of care provided.
