• ISOSTATIC ZIRCONIA

• HIGH TRANSLUCENCY

• Sintering 1530°C - 1580°C   (see Sintering Cycle)

APPLICATION

It is used to realize single crowns, bridges and “full contour” elements.

Dental technicians appreciate Zirconia because it is easy to work with (CAD-CAM technology) and achieves an excellent aesthetic result. This characteristic feeds a growing interest in a more translucent material.

REMARKS ON  TRANSLUCENCY

Zirconia translucency depends on raw material and on sintering parameters. 

•  Higher percentage of Aluminium Oxide in Zirconium Oxide powder means lower translucency

A poly-crystalline product is less translucent than a mono-crystalline one. Due to that Zirconia becomes more translucent by removing Alumina crystals.

• Sintering parameters directly influence the level of Zirconia translucency

Micrographs carried out on Zirconia specimens with different sintering temperatures and permanence time at such temperatures, show that bigger crystals, resulting from higher sintering temperatures or longer permanence, give a greater translucency to the material.

At the same time, the grain size influences in a negative way the values of mechanical, hydrothermal  and aging resistance of Zirconia.

• Raw material is essential to achieve translucency and to avoid the decline of technical characteristics

Hydrothermal and aging resistance, in particular, may have a severe decline if low quality raw materials are used. In this case it is possible to work Zirconia the same  respecting translucency requirements requested by dental technicians, but the final framework during the years may show problems due to the use of a unsuitable material.

ZYTTRIA® material produced by CONCEPT achieves a great result: Zyttria® Z402 EXTRA-TRASLUCENT has a very low content of Alumina (<0,1%) and a sintering temperature between 1500°C and 1530°C, crystals are big enough but with values that are not greater than 300nm.

All these characteristics guarantee a high translucency, but at the same time, suitable hydrothermal characteristics and restance to aging. 

The challenge continues: ZYTTRIA® Z402 EXTRA-TRASLUCENT PLUS 

Thanks to its technical know how CONCEPT has developed  ZYTTRIA® Z402 EXTRA-TRASLUCENT PLUS that unites high translucency and a very high level of technical performance which is a feature of Zirconia.

• ISOSTATIC ZIRCONIA
• HOMOGENEOUS PRE-COLOURING
• HIGH TRANSLUCENCY
• HIGH MECHANICAL RESISTANCE
• HIGH RESISTANCE TO AGING
• Sintering at 1450°C – 1500°C – 1550°C (see Sintering Cycle)

High translucent pre-coloured Zirconia, available with different chromatic characteristics:

•  A1 pre-colored

• A2 pre-colored

• A3 pre-colored

• B2 pre-colored

• C2 pre-colored 

The colouring of the prosthetic structure, after sintering, results homogeneous on the whole piece.

The ceramic pigments are mixed to the Zirconia powder with a technology that it is able to ensure to the granulate a uniform and constant colouring.

The pre-colored colors allow you to have the ideal base  to achieve the required tooth colour and they will avoid the dental laboratory to pay extra costs to create a stock. 

The final characterization of the prosthetic restoration is achieved by using dyes, glazes and through the ceramic layering.

•  ISOSTATIC ZIRCONIA

• HIGH TRANSLUCENCY

• AESTHETIC

• HIGH MECHANICAL RESISTANCE

• RESISTANCE TO AGING

• Sintering at 1450°C – 1500°C – 1550°C  (see SINTERING CYCLE)

A new generation of white Zirconia with high translucency:

• "True to nature" effect
• Optical properties (transmission  and diffusion of light) similar to those of natural tooth tissue
• High mechanical resistance (resistance to dynamic loading and aging)

APPLICATION

It is used to realize single crowns, bridges or “full contour” elements. In any case, it is possible to do ceramic layering.

Dental technicians, because of productivity and competitiveness, ask for very high milling and firing speed, together with the best aesthetic results, characteristics that are not always easy to optimize together.

Nevertheless, translucency is a a feature  that must be related to other characteristics, that are very important for healthcare when using Zirconia for the dental field.

The CONCEPT challenge is to create a material that fulfil the requirements of the modern orthodontics, considering  the responsibilities towards patients' health, with a product  that is able to guarantee very high technical and functional performances (flexural resistance, resistance to acid attacks and aging).

ZYTTRIA® Z402 EXTRA-TRASLUCENT PLUS was born for this purpose, a new generation Zirconia , very translucent at a low sintering temperature.

ATTENTION! 

The final aesthetic results of dental prostheses depend not only on material, but also on the processing.

In order to obtain the best translucency, it is essential that the processing is done with full respect of the material (see our User's Manual/Translucency).
