[QUOTE="Paddy, post: 370975, member: 28758"] Thanks for the reply. I'm just interested in the dental technicians' perspective (not the dentists'),particularly those who do milling for fixed prostheses. I work in England (in the U.K.). There has recently been a seismic shift to milled zirconia with dental technicians suggesting we use more of it. Even my ceramist who has worked some aesthetic wonders with ceramic bonded to CoCr seems to be singing the praises of zirconia. Historically, I've not been impressed with zirconia - issues with debonding of layered ceramic, while the monolithic restorations look artificial. Recently, staining of the monolithic structure has really improved aesthetics and (I presume) I don't have to worry about fracture of layered ceramic. At the same time, there seems to be quite large market for milled CoCr - hard and fully dense as well as soft milled CoCr which needs to be sintered in an argon furnace - is milling CoCr (or even titanium) a thing in the USA, it seems everyone just uses zirconia?
