[QUOTE="Drizzt, post: 171599, member: 4075"] It all comes to what is your working model . Milled CoCr , is IMO better than anything . Other than that , it is also faster . For a 3 unit bridge , I need one hour . Very fast . For soft CoCr , I need 30 minutes to mill it , but it has to be sintered , with all the problems this can cause (wrapping , undetected micro cracks invisible before sintering ),and it needs a 5-6 hour cycle to do that . And I also trust milled CoCr more for screw retained cases . And I don't need a 10.000 euros special argon furnace to sinter it . As for the ZZ furnace that can sinter both soft metal and zirconia , I would still have in my mind contamination and couldn't sleep at night . On the ohter hand , tool cost for soft CoCr is very low , it can be milled by any mill , and Whitepeaks Sintec for example has clearance for anything , any size , including Screw retained and bars . IMO , it all comes to what every lab wants to do , and what needs it has . Both are good , but I think milled CoCr is a lot better . [/QUOTE]
