M-ZR multilayer HT

M-ZR multilayer HT

[Translate to Englisch:]

High performance in a nutshell.

Efficiency

The M-ZR multilayer HT zirconium discs are suitable for single crowns and/or bridges of up to 3 units in the anterior and posterior region (max. 1 pontic). As a result of the favourable coefficient of thermal expansion (CTE) of 10,4 x 10-6K-1 most veneering ceramics can be used.

Aesthetics

The 5-layer shade composition with its gentle, flowing shade gradient ensures nature-identical aesthetics.

  • pre-sintered, fully stabilised zirconium oxide with a cubic-tetragonal microstructure. The cubic crystals occupy a larger volume than tetragonal crystals. This means that light has to overcome fewer interfaces, which leads to higher transparency and therefore improved aesthetics. The material also has greater strength and higher fracture toughness as compared with a lithium disilicate ceramic.

Perfection

The uniaxially pre-compressed and isostatically post- compressed M-ZR multilayer HT zirconium discs excel with their uniform density, good milling properties, high edge stability and precise fitting results.
With a flexural strength of 840 MPa, the new multi-layer zirconium offers high stability for monolithic crowns and bridges in the anterior and posterior region.
