Zircon–oxide Crowns

Technology of the 21st century!

Answer to the highest aesthetic and functional claims! The zircon is produced in a special manufacturing process and displays a high flexible stability. When a stability of 150-200Mpa is achieved in case of normal full ceramic, Zircon oxide displays this tenfold ca. 1200Mpa. These crowns or bridges are produced with a so called CAD/CAM technology. The principle is that the prepared stumps on the basis of a precise dental impression are scanned by a computer. This data is processed and saved, CAD (Computer Aided Design). Now the production of the framework made out of zircon follows with the aid of a CAM system (Computer Aided Manufacturing) which facilitates the precise cutting out of a prefabricated zircon oxide bloc. In doing this the scanned Data is transferred by a rotary cultivator controlled by a computer. The dentist tests this zircon framework at the patient, then the coating with special porcelain follows. This is applied in layers and burnt and is certainly adapted to the colour, form and the biomechanical claims of the actual teeth. Thos CAM/CAD system is from the company KaVo Everst with herazircon porcelain.

Zircon crowns correspond to the most modern technology and serve with magnificently aesthetic results. The framework consists of white zircon – easy, gracile, but at the same time very stable – very accommodating to tissue. The achieved transparency is optimal. This method is optimal for the production of crowns but also multi-chain bridges due to its high stability.

Advantages:

• high stability; applicable in the incisor region as well as in the region of the side teeth
• can be used in case of very long round bridges
• magnificent aesthetic
• high precision
• no allergies

Disadvantages:

• none

When should absolutely be used Zircon?

• exchange of old metal ceramic bridges, often with dark margins
• root-treated, filled or coloured teeth
• with zircon pins destroyed root
• Zircon abutment on implants
