 Cercon® Zirconia is an innovative CAD CAM system for esthetic metal-free crowns and bridges. The reliability of Cercon® Zirconia restorations is backed by more than five years of proven clinical success.
Manufactured using a computer controlled milling machine, these restorations are machined to precise tolerances, with outstanding fit and marginal integrity, and of course STRENGTH!. Cercon Zirconia blocks are manufactured in both white and ivory shaded blocks so darker shades are easily achievable without any infiltration required.
Indications:
The system is used to fabricate anterior or posterior single units or multi-unit bridge restorations out of translucent, biocompatible zirconia,  the strongest and toughest dental ceramic. Cercon® Zirconia restorations can be placed with conventional cementation or adhesive bonding techniques.
More than 1,000,000 units have been placed worldwide since its introduction in May of 2002.
Cercon® Zirconia is unique among dental ceramics in that it exhibits a physical property called "transformation toughness". When stress is applied to the material, it goes through an instantaneous phase transformation that acts as a clamp to prevent crack development. This phenomenon is of great importance in fatigue situations such as those caused by chewing forces on restorations.
