I think it has it's place, esp. if you have a long term tx plan.
Example, if you are remaking a denture, then placing implants and
need conversion to a hybrid. If you have an electronic memory of
which teeth goes well, you can recreate a surgical guide,
you can design the implant placment to be idealized for a hybrid
and then even possibly recreate the same hybrid in about 5-10 years
when the denture teeth needs to be 'retoothed'.
I won't count on an intraoral scanner for impression for full denture,
but the prosthetic end has it's needs that can be addressed with
a digital solution.
