Audental zirconium

[DPS]

Has anyone used audental zirconia discs ? Would you say its of average quality or low ?My main concern is strenghth and fracture toughness . Most of our work load is single copings and bridge copings up to 6 units .

So i started using this zirconia 4 months ago and here is my experience if anyone is interested:
I only used audental Ht , as framework , with audental liquids . Colors were fine . I went with their recommended 11 hour cycle and so far , have not had any fracture and warpage .
One thing that really bothers me is that these blanks wear burs very quickly , i had to change 2 burs in 4 month and also there seems to be inconsistent quality among the blanks , some being hard on burs and some being extremely hard ! ( i only used the original sirona DC burs which used to last up to 5 or 6 months with pritidenta , zirconzahn ,... ) .
I emailed them about this issue and they said they also have softer blanks with scaling factors between 1.242 and 1.245 . I cannot confirm that yet.

Thanks for posting your follow-up feedback, but inconsistent discs and an 11-hour sintering cycle even for single copings? would make it time enough for me to move on to a different zirconia.

Hello, Could you please contact me for details

Sounds like a bad product overall, why bother any further?

the life of a milling burr depends on unit/time counter not just span of months, I have tried in the past some zirconia and you could hear the zirconia hardness during milling.
milling burrs are definitely different from each manufacturer, and the original burr is always the best
