Not all zirconia
is called DIAZIR
There's a lot of zirconia on the market
01
More brittle: So far, the crown has broken in about 2% of cases in the process of being put in place by the chair.
The thickness should be increased More tooth preparation is required, resulting in excessive grinding of the patient's healthy teeth.
02
Not suitable for posterior teeth Low strength and poor toughness
03
Not suitable for operation Color instability
04
however, after an authoritative investigation
the zirconia ceramics on the market have the following problems
In the US authoritative CR2016-11-14 Clear Zirconia clinical Follow-up report for certain brands, we looked at seven zirconia brands (285+ molar crowns made by 40 dentists) and found the following key differences in zirconia brands 8 months after clinical surgery:
The reasons are as follows:
1. Low flexural strength: Only 600 MPa
2. Poor crack propagation resistance leads to short clinical service life
Product features
·The grain size is small

Comparison of microstructure between fully sintered DIAZIR zirconia
After magnification of 30000 times, we can clearly see that DIAZIR zirconia crystal size is uniform and more evenly distributed, which is one of the reasons why DIAZIR has superior mechanical properties.
Zirconia particles of some other brand are only 20 000 times larger, but they are still huge, with large size difference and uneven distribution, which leads to the fragility and fracture of ceramics.
