Zirconium  is a material with excellent mechanical properties, which is why it has become an increasingly popular solution for restoring posterior teeth (fullcontour/monolithic) or for ceramic frameworks for bridges and crowns.

Zirconium  being conventionally less transparent than ceramics (disilicate/feldspathic), has so far been limited in use for the anterior area.

The new range of Katana ST and UT zirconium from Noritake, thanks to its superior translucency, changes the conventional view of zirconium, opening the way to potential new ways of using it in aesthetic dentistry. Katana ST/UT zirconia has different levels of translucency and mechanical properties depending on the applications for which they are recommended.

Choose the right zirconia according to the table below:


Katana ST/UT zirconia has superior mechanical characteristics to ceramic materials (disilicate/feldspathic). In order to achieve durable restorations, the thickness of the zirconia must remain equivalent to the thickness at which ceramic materials are used.

Sintering programs

KATANA multi-layer zirconia discs, known for fast Full-Contour/Monolithic restorations, are now sinterable in 90 minutes (in fast sintering furnaces*) *Tested for AUSTROMAT 674i, inFire HTC speed and Sintra Plus furnaces; valid for Katana ML/HT, STML/UTML zirconia discs.

UTML - Ultra Translucent Multi Layer Zirconia

Zirconia with glass-like translucency, with the highest level of translucency 50% MultiLayer technology - graded colour and translucency

For veneers and anterior crowns a high level of translucency is required to improve the harmony of the restoration with adjacent tooth structures and prevent a visibly whitish appearance. UTML is entirely highly translucent, with the colour intensity greatly reduced in the incisal area to highlight the translucency present in the enamel of the natural teeth. This material is indicated when a blunt shade can be used. Before choosing the zirconium that you will use, carefully evaluate the shade of the dental blunt to determine if it is too discoloured or pigmented to be used with this transparent material.

Multi-Layer Technology Noritake Katana ML (Multi-Layer) are the first polychromatic, multi-layer zirconia discs, ideal for quickly achieving natural-looking, Full-Contour/Monolithic restorations.

It is a zirconium with superior aesthetics, similar to natural teeth, achieved due to the gradation of translucency and shade saturation from the collar of the tooth to the incisal.

The disc is made up of several overlapping, pre-shaded layers with gradual translucency, each representing dentin, enamel and transition areas respectively. The layers are evenly interwoven, with no visible boundary lines.

1. 35% dentin layer (of disc thickness)

2. transition layer 1 15%.

3. transition layer 2 15% (15%)

4. enamel layer 35%

Thus, a restoration similar to natural teeth is achieved quickly and with remarkable results.
