Instructions for use Cercon® base, Cercon® ht, Cercon® xt

Product description:

Cercon® base, Cercon® ht and Cercon® xt blanks are made of yttrium oxide- (yttria-) stabilized zirconium oxide
(zirconia) (Y-TZP)They are used in fabricating frameworks for fixed prosthetic restorations
Depending on the framework design, Cercon® base, Cercon® ht and Cercon® xt frameworks can be ceramically
veneered or deli vered as fully contoured restorations Which blank is selected will depend on the tooth shade to
be reproduced and the space available for the veneer With fully contoured restorations, no space is required for
the ceramic veneer, which may allow the dentist to preserve more of the tooth substance during preparation
Framework material
Temporary cementation
Definitive cementation
Objects are individually fabricated to your digital design specifications such as anatomic contour, framework and wall thickness, connector diameter and cementing gap.
Technical specifications Cercon® base, Cercon® ht:
• Type II, class 5
(pursuant to DIN EN ISO 6872:2015)
• CTE; 105 μm/m·K (25 – 500 °C)
• Modulus of elasticity: 210 GPa
• Flexural strength: approx 1 200 MPa
(three-point flexural testing)
Composition (in % by mass) Cercon® base, Cercon® ht:
• Zirconium oxide
• Yttrium oxide 5 %
• Hafnium oxide < 3 %
• Aluminium oxide, Silicon oxide, other oxides < 2 %

Indications for use:

Indications in the anterior and posterior segments
Cercon® ht:
Cercon® ht is indicated in the anterior and posterior
segments for:
• Crowns
• Telescopic primary crowns
• Multi-unit bridges (with no more than two pontics be-
twe en abutment crowns; with no more than 6 units*)
• Two piece abutments**
Cercon® ht can be used as a substructure (framework) which is then veneered with a dental veneering ceramic
or can be used for full-contour application (without veneering) as well In the case of telescopic primary
crowns, the substructure is not veneered
Cercon® base is indicated for crowns, multi-unit bridges and inlay bridges Applications include both anterior
and posterior regions
