6 CERAMIC MATERIALS

VITA Mark II is the CEREC material with the longest track record. This feldspar ceramic is available in monochromatic blocks in a variety of 3D Master shades. This same material is also available in a polychromatic version (VITA Triluxe) with differently shaded layers.

The monochromatic CEREC Blocs as well as polychromatic CEREC Blocs PC available from Sirona are also made of feldspar ceramic. They are available in the most popular Classical and 3D Master shades.

The Ivoclar Empress CAD blocks (formerly called ProCad) consist of a leucite-reinforced glass ceramic material. They are available in the shades A-D, with two degrees of translucency respectively. Ivoclar also markets polychromatic blocks (“Multi”).

The lithium disilicate glass ceramic blocks (e.max CAD LT) can be conventionally cemented.


6.1 STRENGTH

Dental ceramics can be divided into two categories according to their microstructure:

1. Aesthetic enamel-like ceramics with a glass content in excess of 50%. The physical characteristics (e.g. strength, hardness, abrasion properties, opacity, and colour shade) can be modified by the addition of fillers.
2. Polycrystalline ceramics for frameworks. These consist of particles with an identical crystalline structure. These relatively opaque materials are much stronger than glass ceramics.

Nearly all these versions are available as conventional laboratory ceramics and as machinable CEREC ceramics. Polycrystalline zirconium oxide and aluminium oxide ceramics are reserved exclusively for CAD/CAM systems.
CONCLUSION CEREC and inLab systems can machine all the relevant types of dental ceramics and hence are future-compatible and universally deployable.

6.2 ABRASION

Veneering ceramics in particular have been criticized for causing wear to the antagonists and for being more abrasion-resistant than tooth enamel.

As long ago as 1991 Krejci demonstrated that VITA Mark II displays the same abrasion properties as natural enamel.

The surfaces of CEREC do not need to be polished or glazed. There is no difference with regard to abrasive wear and tear of the tooth enamel.

The abrasiveness of VITA Mark II does not differ significantly from gold. The material itself is abraded at the same rate as gold.

CONCLUSION CEREC ceramics do not damage the antagonists and display abrasive properties that are similar to gold.
