BruxZir zirconia is significantly stronger than the Bruxer Aesthetic (I use Keating). I tend
to go with the full BruxZir zirconia crowns for second molars and the Aesthetic for most
everything else because the Aesthetic is significantly stronger than E.max. Keating does a
great job with both.
The BruxZir crowns are more visually opaque but thus far no one minds at all. They've
finally solved for me the problem of patients who can break pretty much anything you stick
in their mouths. But, always leave 2mm occlusal clearance, no matter what anyone tells you. ■

Here is an example of the same crown made from
three different materials. The 3Y zirconia means that it
has 3mol% yttria and almost no cubic phase. These are
materials like BruxZir. The 5Y zirconia has 5mol% yttria
and about 50% cubic zirconia. These are materials like
BruxZir Anterior.
The 3Y should look more white opaque than the 5Y. But
the 3Y is stronger (about 1000MPa) as compared to around
600-700MPa for 5Y. And the top one is E.max.

The 3-point bend flexural strength values (MPa) of:
3Y Zirconia: 1194 ±111 (Katana HT),
5Y Zirconia: 688 ±159 (Katana UTML),
lithium disilicate: 450 ±53 (e.max CAD LT)
Taken from:
ncbi.nlm.nih.gov/pubmed/29310875
Ivoclar currently reports a 500MPa for E.max but that is biaxial flexural strength testing.
And as Dr. Lane Ochi implied, E.max will increase in strength when bonded. That's why the
recommended minimum thickness for E.max is 1mm, but that is only when bonded. If luted
with RMGI, it is still 1.5mm. ■

My lab uses Z360. Never had one break in service in 8 years. My occlusal clearances are
about 1mm on average. I'm frankly, amazed. After much scientific research I've decided zirconia
is magic. ■

And after replacing a number of them I have decided it's not. ■

I wonder what is the reason for replacement? I've only had to replace three of mine over
the past decade. Two wore a hole through due to inadequate occlusal reduction and one
broke on the facial. And in the broken facial, I'm 99% sure we cracked it at try in. All =
operator error.
I find my margins are undetectable and they look awesome versus average PFM and even
E.max. With the presinter coloring and postsinter staining, my lab can make them look as good
as E.max, for an extra small fee. But as Dr. Kanca said, drop it 2mm and give sufficient axial
reduction, I call it between gold versus PFM axial reduction. I too think it's borderline magical.
So why all the replacements? ■
