JustZr
No Frills Zirconia.
JustZr™ was our second ‘own brand’ of zirconia products, launched in 2010. In todays competitive market, we saw the need for an economy, no frills zirconia at a super low price, that still met the quality standards we like to maintain.

Why Isostatic
Many zirconias are pressed in only one direction. This is called uniaxial pressing and produces blocks that are inconsistent in density from one part of the material to the other. This results in uneven shrinkage which can lead to poorly fitting margins and can produce chips and microcracks.
JustZr is isostatic, which means it is pressed from all directions. This results in an even density over the whole block and can be relied on to produce consistent and accurate margins whether milling single units or large spans. Isostatically pressed zirconia is more expensive to produce but is essential for a guaranteed marginal fit, strength and longevity.
