Sintering at 1450°C - 1500°C (see SINTERING CYCLE)
APPLICATION AND CHARACTERISTICS
Zirconia is suitable especially for anterior tooth area, veneers and max. 3 unit bridges for posterior tooth area.
It’s also possible to realize single crowns, inlays or onlays.
As the molding is made by Isostatic pressing Zyttria Z403 ANTERIOR has better technical performances.
-
Perfect aesthetic
Translucency comparable with Lithium disilicate
Light transmission = 50% approx.
Superior translucency (20% approx.) regarding to other translucent ZYTTRIA materials, Z402 Extra-Traslucent and Z402 Extra-Traslucent Plus.
- Double flexural strenght regarding to Lithium Disilicate
Flexural strength (Bending strength 3 points)= 600 +/-100 Mpa approx., e.g. double regarding to parts made of Lithium Disilicate (250/350 Mpa).
- High resistance to aging
Zyttria® Z403 ANTERIOR is different from other types of High Translucency Zirconia due to a higher content of Yttria (>8,5% of weight).
The microstructure and the allotropic status of Zyttria® Z403 ANTERIOR at room temperature, are completely tetragonal in stable form (with small cubic quantity) if compared to other materials which, however, have a mixed allotropic structure (tetragonal and monoclinic).
This characteristic, in addition to a higher translucency (greater light passage), produces a very high resistance to chemicals and a high resistance to aging.
PROCESSING
ZYTTRIA® Z403 ANTERIOR is suitable for milling also in dry systems, with normal cutters for Zirconia.
In case of water milling, in order to achieve the best result, follow the instructions in the User's Manual.
Pre-colouring process is the same used for other materials with a high Zyttria® translucency.
In order to enhance aesthetic characteristics , use color liquids for brushing technique “AQUA-P for Anterior”, which are specific to colour Zyttria® Z403 ANTERIOR.
This way, it is possible to create devices which are completely anatomical, avoiding the problem of ceramic chipping in the anterior tooth area.
