Zirkon Biostar
Zirkon BioStar, Zirkon BioStar Z or Zirkon BioStar Colour are dental blanks (semi-finished products) made of yttrium stabilized, pre-sintered zirconium dioxide for milled production of crowns and bridge frameworks on commercial CAD/CAM systems or hand-operated copy-milling machines with outstanding biocompatibility and high resistance against tension and pressure.
Because of the special single cip™ production process (after the uniaxial pressing, every blank will be packed separately and pressed under an isostatic vacuum) we guarantee thru different batches a constant high quality. The pre-sintered blanks are eminently suitable for all open machining and have excellent edge stability. On account of the special production process, extremely constant firing shrinkage is achieved, even over different batches, meaning that in most cases it is not necessary to adjust the enlargement factor on the CAD/CAM unit. Only diamond-charged grinding tools or hard metal tools are to be used for machining. The material types Zirkon BioStar and Zirkon BioStar Z differ regarding the strength value achievable after the final sintering and contain a different amount of aluminium oxyde. They differ in the manner of whiteness and translucency and both show a different resistance against hydrothermal aging. Zirkon BioStar Colour is already persistent coloured in the pre-sintered stage. |
