[QUOTE="Scorpy, post: 355967, member: 26877"] Thanks for the reply, I appreciate it. If we compare with e.max (lithium disilicate),these prettau crowns are stronger, but less aesthetic. And if we compare with PFZ, the prettau crowns don't have the 2 weak points that PFZ has - the place where the porcelain meets the zirconium substructure, and the porcelain itself. My friend says he wants to sacrifice a bit on the aesthetic side, in order to get a crown that's a bit stronger and may last him longer, and that's less likely to chip. I can't blame the guy. The one thing that worries me a bit is that all of these monolithic high translucent zirconia crowns are a newer generation crowns, so they haven't been tested as thoroughly through the decades. And if you put them on all of your front teeth (1 crown per tooth, not a bridge),and then an unexpected problem occurs, you're in for a world of hurt. [/QUOTE]
