In green state zirconia (i.e. raw, non-sintered zirconia powder), this method is known to create density heterogeneities which makes for inconsistent mechanical properties throughout the blank . This makes dry pressing unsuitable for larger pieces such as bridges, where the density irregularities will be more pronounced; however, it is still ...
The blocks milled in a chairside or laboratory milling machine are partially-sintered zirconia, and volumetrically shrink approximately 25% to 30% during the sintering process. 22 Milling an enlarged restoration presents a significant advantage to zirconia, effectively reducing the diameter of milling tool the same 25% to 30%.

Milling accuracy is dictated by materials properties. High material hardness means low machinability and more involved forces [].Titanium and densely sintered zirconia are difficult to machine, rendering the bur more susceptible to tool failure and wear [50, 90–92].Consequently, the internal surface might be under-milled, hindering the fit of the restoration [].
An attempt was made to examine the optical parameters of 5Y-PSZ monolithic pre-coloured zirconia using different milling methods and artificial ageing. The results confirm that, to achieve a high degree of translucency and lifelike restoration, dentists must follow the manufacturer's instructions for dry-milling CAD/CAM zirconia materials. 4.2.
In 2016, Sirona updated their mill lineup with dry milling technology to speed up the processing of zirconia. This was accomplished by adding a dust vent on each side of the milling chamber and a suction unit to remove and store the zirconia dust. According to Sirona, there is no difference in accuracy or quality between wet and dry milling.

Fig. 1 collects the Raman spectra of the sintered composites and the monolithic 3Y-TZP ceramic. In Fig. 1a the six theoretically predicted Raman bands for tetragonal zirconia at 160, 266, 327, 470, 612 and 647 cm −1 are clearly observed, confirming that the tetragonal phase is the main one in the ceramic. The characteristic peaks of the graphitic structures are clearly …

The fine milling will reduce the chip thickness and minimise surface roughness [57–59]. In relation to zirconia milling, common disadvantages of hard machining are that it is time consuming and that the zirconia phase transformation to monoclinic phase occurs [18, 44, 60]. Such a phase transformation will exacerbate surface microcracking and ...
In addition to the increased sand supply, over the course of 2006 and the first half of 2007 the global zircon milling capacity is estimated to have increased by nearly 10%. The reason is easy to understand. As Figure 1 shows, the margins enjoyed by zircon millers have widened considerably over the last 3 or 4 years.
