Isostatic Pressing

Each Zirconia Blank is isostaically pressed for consistent results every time. We do not cut corners, as we use the exact same zirconia for our 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 to define the product, rather than the characteristics. The real definition lies in Translucency Parameters (TP), and Contrast Ratio (CR). The Contrast Ratio for Alien Zirconia Blanks are >34:1 CR %, one of the highest translucent zirconia offered in the industry. 


We research, and use 98 mm Alien Zirconia Blanks in our milling center everyday. We know our zirconia is out of this world. Many labs, doctors, and patients may be unaware Zirconia is a radioactive material. Safety is the main focus of the company, and we would not use unsafe materials exposing our technicians to unsafe materials. 

Our Research and Development engineers continually test the zirconia powder for any traces of radioactivity, and makes sure the zirconia is 100% safe every time.

Ask a Question
  • how many teeth can block zirconia made

    The Average is about 20 with Sum3D (Millbox). Each Cam software, drill diameter, and spacing can give different averages. 

  • I ordered a 98mm Alien HT puck, and am looking for sintering temps . Is there a sheet you can email me.

    Sintering Temps are now available on the product page. :)

  • We use DentalDirekt DDbio ZX2 liquids. Is this compatible with Alien HT zirconia


  • Do you have an authorizate distrubor in balkan countrys.

    As of 05/14/2018 we do not have a distributor in that region.
