This is an improved, more accurate CBCT-only approach and is one of two edentulous protocols that do not require an optical scan of either the patient’s tissue or prosthesis (the other is the EC-D protocol). It was developed by Dr. Michael Scherer (whose photography is used above, with permission) and it provides a vastly improved CBCT image of the intaglio of the denture; the best possible without utilizing an optical scan. You can view his description of this technique in his Linkedin article: The role of radiopaque PVS in CBCT imaging for full-arch reconstruction.
Finally, unlike the EC-D protocol, you can use an unprocessed denture waxup, since the intaglio is captured with great accuracy. This saves the time and cost of making a duplicate appliance.
