Cercon® ht Instructions for Use

Product description:

Cercon ht blanks are made of yttrium oxide- (yttria-) stabilized zirconium oxide (zirconia) (Y-TZP).
They are used in fabricating frameworks for fixed prosthetic restorations.
The material is an oxide ceramic material characterized by its particularly high strength. Depending on the
framework design, Cercon ht frameworks can be ceramically veneered or delivered 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.
