M-ZR white HT

M-ZR white HT

[Translate to Englisch:]

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:

  • crowns and bridges of any span and tertiary constructions
  • cut back (one layer)
  • in conjunction with M-ZR coloring liquids, highly aesthetic veneering work of any span
  • 40% translucency (measured by means of a spectrophotometer on 1 mm thick, polished samples)
