M-ZR white HT

M-ZR white HT

 

High Translucent

Through the development of this innovative material, we have combined all the well-known, positive mechanical properties of “white“ zirconia with a significant increase in translucency.
The M-ZR white HT concept convinces with its cost effectiveness and also offers all the advantages of full-ceramic zirconia dentures.

Perfectly suitable for:

  • monolithic crowns and bridges (of any span range)
  • especially for monolithic bridges ≥ 4 units
  • cut back (one layer)
  • high aesthetic veneering (of any span range)
  • 40% Translucency measured by means of a spectrophotometer on 1 mm thick, polished samples
