Why labs mill with Alien HT
Compatibility
98mm with a 10mm step. Compatible with Wieland, VHF, Roland, and most open CAD/CAM milling machines.
Isostatic pressing
Each zirconia blank is isostatically pressed for consistent results every time. We do not cut corners — we use the exact same zirconia for our own milling services.
Gentle on your mill
Alien Zirconia disks are softer in the green state than generic zirconia. This extends the life of your spindle and tools.
Translucency factor
“High translucency” has become a loosely used term. The real definition lies in Translucency Parameter (TP) and Contrast Ratio (CR). Alien Zirconia blanks measure >34:1 CR, among the most translucent zirconia offered in the industry.
Research and safety
We research and use 98 mm Alien Zirconia blanks in our milling center every day. We know our zirconia is out of this world.
Many labs, doctors, and patients are unaware that zirconia can carry trace radioactivity. Safety is the main focus of our company, and we would never expose our own technicians to unsafe materials. Our Research and Development engineers continually test the zirconia powder for any traces of radioactivity.
