Description

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. VITA TITANKERAMIK is for veneering of pure titanium and titanium alloys (Ti6Al4V). The special 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 • biocompatible •corrosion-resistant •neutral taste / hypoallergenic •high mechanical strength / lightweight • low thermal conductivity Lattice transformation 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 -titanium. 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. Passivation layer Titanium has a strong tendency to spontaneously form a very fine oxide layer at room temperature.
