Name and general description
Dental blanks made of Zirkon BioStar, Zirkon BioStar HT, Zirkon BioStar Z or Zirkon BioStar Colour are dental
materials (semi-finished products) made of yttrium stabilized, pre-sintered zirconium dioxide for milled produc-
tion of crowns and bridge frameworks on commercial CAD/CAM systems or hand-operated copy-milling ma-
chines with outstanding biocompatibility and high resistance against tension and pressure.
The pre-sintered blanks are eminently suitable for 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.
Geometric variants
The blanks are manufactured in various product shapes and sizes. Discs 90 to 110 mm in diameter and 10 to 28
mm in height (as full disc or with flange according to customer requirements). Cuboids and cylinders in various
dimensions Other dimensions according to customer requirements are possible by agreement
Material types
The material types differ regarding the strength value achievable after the final sintering and contain a different
amount of aluminum oxide. 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. Consequently, the dental surgeon or dental technician can select the ideal base material for the respective
case. On account of the high strength values, both materials are also suitable for multiple-element posterior
bridgework.
If required, additional physical and chemical key values are referred in our material data sheets. All material
types were tested by an accredited testing laboratory regarding biological compatibility and classified as emi-
nently suitable for use in the dental sector.
Indication
Crowns in the anterior and posterior dental area and also bridge frameworks with a maximum of two pontics.
When undertaking the preparatory work, it must be ensured that there is an adequate connector surface bet-
ween the abutment crown and the pontic and adequate minimum wall strengths.
Contraindications
In the case of bruxism, inadequate hard tooth structure or insufficient space, the use of full ceramic crowns and
bridges is not recommended or only advised in some cases. The same applies in the case of inadequate oral hy-
giene or inadequate coordination of masticatory movements.
A full ceramic crown or bridge may also not be used in the event of unsatisfactory preparation results or in the
case of production faults.
Preparation information
The minimum wall strength values in the following table are merely reference values. The decision on the man-
ner and undertaking of the preparation is the responsibility of the dental surgeon and dental technician.
Minimum wall thicknesses:
