Digital scanners came onto the market in the mid 1980s. The introduction of the CEREC CAD-CAM system. Over a few decades, they have improved to a level where they can now take accurate scans of teeth and hugely improve workflows.
Historically, a clinical would have had to take a physical impression, then wait to to send it to the laboratory before the lab could complete the work. Now, one can scan and immediately send it to the lab or even 3-D print the work where possible.
This is a big change.
However it is still just another way of doing impressions. It is still impressions done more efficiently and in a patient friendly manner.
So do you see it as evolulationary (an improvement in the impression workflow) or revolutionary (a disruption in how the process is done)?
