[QUOTE="Pronto, post: 323992, member: 590"] We experimented for years with different PD/AG alloys for pfms. They all sucked. Finally we just told the drs we are using Argen 52SF high noble for pfgs and that is that. If they don't want pay the price they can use zirconia or emax. No way are we going to play with a new crappy PT alloy. At some point you have to put your foot down and tell them you won't work with that junk. PD is not a bargain anymore so it doesn't matter anyway. We call those Richmond crowns a post crown. They never fit right so we told the drs we will only do a separate post and core and crown over. Magically the fit and margin seal was solved. Duh. [/QUOTE]
