"What makes priti®multidisc ZrO2 Multi Translucent so special?" Following popular demand, this blank combines the positive properties of the already established zirconium dioxide qualities 3Y-TZP and the highly translucent 5Y-TZP in the enamel and in the body.
Maximum safety? A scientific study proves it. Click here for the original report: Link to the study
Our strong multi-talent can be used for all indications. Highly aesthetic monolithic, full-anatomical crowns, partial crowns and bridges up to 14 units, inlays, onlays, veneers and abutments. Its natural aesthetics and high stability make it suitable for the anterior and visible tooth region. In addition, the cervical opaque zirconium dioxide has good masking qualities. All processing techniques: Staining, cut-back and veneering techniques are possible.
The combination of 3Y-TZP (Translucent with very high strength) and 5Y-TZP (High Translucent with very high translucency) gives a highly aesthetical effect and reliable strength for an unrestricted range of indications. In addition to a smooth transition between the layers within the blank or restoration, this product also has good masking qualities and high stability throughout the blank.
The smooth transition between the layers results in a gradual progression of strength within the blank or restoration. Multi Translucent is therefore suitable for a wide range of indications.

In order to achieve optimum results and avoid errors, correct application is very important. We have compiled the most important instructions for correct use under the following points.
|Systems must be constructed of the following specifications:
|Minimum framework thickness
|Minimum framework thickness
|Anatomically shaped (supporting veneer ceramics); fully anatomical
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.
|Tool path distance
|Step down/step over
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.
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.
Restorations can be cemented conventionally with a zinc phosphate or glass ionomer cement or with self-adhesive and fully-adhesive fixing material.
Any ceramic veneers recommended for zirconium dioxide ceramics may be used.
