priti®multidisc ZrO2 monochrome Extra Translucent

For all milling machines that accept round blanks with a diameter of 98.5 mm


priti®multidisc ZrO2 Extra Translucent is the most flexible zirconium dioxide, for all indications - a real all-rounder. It combines strength with aesthetics, the genuine, natural zirconium dioxide option for you.

(4Y-TZP) available in white, 45% translucence, flexural strength > 1,150 MPa.

INDICATION

You can use priti®multidisc ZrO2 Extra Translucent in white to fabricate anterior and posterior custom restorations on natural abutment teeth and implants. Its unique feature is its balance between high translucence and high flexural strength. This means the material can be recommended without reservation for flexible use across a particularly broad range of indications.

MATERIAL

  • Zirconium dioxide Type II, Class 5 (DIN EN ISO 6872)
  • Flexural strength > 1,150 MPa
  • High translucence of 45%
  • Very high aesthetics
  • CTE 10 ·10-6 · K-1
  • Thin wall thicknesses of 0.4 mm for single crowns in the anterior tooth area and 0.6 mm in the posterior tooth area
  • Precise edges and margins due to highly compacted material
  • Veneering possible with any ceramic mapped to the CTE of ZrO2
  • Biocompatible

CHEMICAL COMPOSITION

Zirconium dioxide (ZrO2/HfO2): 92.1 - 90.7 %
Yttrium oxide (Y2O3): 6.65 - 7.95 %
Aluminum oxide (Al2O3): < 0.2 %
Other oxides: < 0.7 %

SINTERING

Recommendation for standard sintering:
Heating and cooling rate 10°C/min
Hold time 120 minutes at 1,450°C
Total sintering time approx. 7 hours

Recommendation on rapid sintering: (for bridges with up to 3 pontics)
Heating rate 10°C/min
Hold time 30 minutes at 1,500°C
Cooling rate 40°C/min
Total sintering time approx. 4 hours

Sintering together with other materials could cause unwanted changes in color and translucence. This applies particularly to materials processed using dye liquids. Sintering beads must also be replaced to avoid dye liquid residues.

It is particularly important to clean sintering furnaces that are contaminated by dye liquids before sintering a pre-shaded material for the first time. This prevents unpleasant surprises and allows optimum photo-optical results for the zirconium dioxide.


VENEERING

Any ceramic veneers recommended for zirconium dioxide ceramics may be used.

MILLING

Reduce feed rates during rough machining: The quality of milling depends on several factors including the machine, machining strategy, zirconium dioxide, etc. To ensure that you can achieve optimum milling results from the start with high translucence blanks, we recommend using a lower speed than with opaque materials during rough machining.

Coated milling tools: These offer the benefit of low wear with longer tool life.


ADJUSTMENTS

Any adjustments required to the sintered restorations once compacted must only be carried out using diamond-coated tools to prevent damage to the material caused by local overheating or exposure of the surface of the restoration to excessive force.


FIXING

Restorations can be cemented conventionally with a zinc phosphate or glass ionomer cement or with self-adhesive and fully-adhesive fixing material.

What our customers say about us.

"pritidenta systematized zirconia for success.
Very few of the zirconia blanks on the market stand out as unique. pritidenta found a way with excellent, natural-looking results through CAM techniques. Nesting high or low is not new, of course, but nobody has gone this far to make sure the end results are consistent and predictable..."
