priti®multidisc ZrO2 multicolor High Translucent

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

priti®multibloc ZrO2 multicolor High Translucent is the material of choice for the most vibrant, highest aesthetics on restorations with up to three pontics.

(5Y-TZP) available in 7 color gradients and 1 bleach shade, 49% translucence, flexural strength > 650 MPa.
Adjusting the position in the same disc allows all 16 Vita shades to be achieved with just 7 blanks!

 

Indication

You can use priti®multidisc ZrO2 multicolor High Translucent to fabricate inlays, onlays, veneers, partial crowns, anatomically reduced and monolithic, fully anatomical crowns and bridges (up to three pontics) for anterior and posterior areas Translucence is comparable to that of lithium disilicate. Its high translucence and integrated color gradient mean the material is particularly suitable for efficient fabrication of non-veneered restorations.

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.

COLOR-CODING

Through the measurement of the restoration height an even more precise positioning and color assignment can be made to the appropriate blank height. The positioning data apply mainly to anteriors. For posteriors we recommend a lower position. This prevents fused cusp areas appearing too white. An additional positive effect is the warm base hue due to the fissure pits.

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..."
