The thermal expansion coefficient (COE) and the physical properties of VITA TITANIUM CERAMIC have been perfectly matched with the material titanium. Correct processing ensures reliable bonding between the titanium substructure and VITA TITANIUM CERAMIC.
The dental technician creates brilliant shades with different translucency using perfectly matched materials. VITA TITANIUM CERAMIC fulfills all requirements to achieve fine esthetic results.
is for veneering of pure titanium
and titanium alloys (Ti6Al4V).
properties of Titan:
•titanium 1/degree of purity 99,5 - 99,8%
• Vickers hardness 180-250 (degree 1-4)
•thermal expansion coefficient 9.6 x 10-6
•neutral taste / hypoallergenic
•high mechanical strength / lightweight
• low thermal conductivity
The lattice transformation of titanium at
882 °C is of particular importance for the
dental technician. Below this crystallisation temperature titanium occurs as
hexagonal -titanium, and above this
temperature as cubic body-centred
As well as making the material very
brittle and impure, this transformation
results in a 17% increase in volume.
The surface of the titanium is hardened by
diffusion of elements (oxygen, carbon, ...).
This progression of hardness is caused by
the reaction of the molten titanium with
ingredients of the investment compound.
The marginal layer becomes strongly
embrittled and impure. The -case layer
must be removed as a preparatory measure
before veneering with dental ceramics.
Titanium has a strong tendency to spontaneously form a very fine oxide layer at room
