Cubex2 , help me out please

[DPS]

I have a cubex2 full zirconia crown that i had to grind a bit to adjust occlusal. Do i need to run a regeneration cycle for this ? Anyone has the firing chart for this cubic zr ? I asume it should be different from tetragonal zirconia ?

I assume this crown is sintered and glazed. Just polish the ”bit” spot. Do you have some zircon Brite? You could reglaze the crown also. Use your normal glaze cycle.

This is exactly how we would handle it

What i'm saying is , given that cubex2 strength is 750 mpa , can i help release some of the stress induced by grinding , through a regeneration bake ? I'm worried it might break in the mouth. It wasn't just one spot .
I did take my time with the design to ensure the occlusion was off , but then on the model it's not . Had to grind post- sinter.

Should still be fine. Unless you agressively ground and looked like an arc welder, or is below minimum thickness.

I believe it's a 5y zirconia?, so any micro cracks you may have put into it adjusting it will be there, they cannot be regenerated out, healed, with a firing cycle. If any micro cracks are shallow, they can hopefully be smoothed out at slow speed with water, with the likes of a Dialite blue wheel etc and polished like has been mentioned with the previous posts.

Y3, y4, y5 zirconia?

A dentist has recently been asking us about this and I'm not too sure what it means. I know that a y3 is stronger/better than a y5 and the y is referring to the yttrium content of the zirconia but past that I don't really know anything. Out of the zirconia we use, I've been told that the...
