Remember Typewriters? Remember film cameras?
Soon we will be saying remember alginate and PVS?
Digital impressions are to traditional impressions as typing is to word processing. I am using a Trios exclusively for impressions including full mouth impressions and bites for sleep apnea devices and it is marvelous.
One of the best features is that I can easily go back over an area and fix any discrepancies in the digital impression. Try that with alginate or PVS.
