BTEETH:
COLOUR LINE FOR DENTAL CERAMICS ZIRCONIA
The technological evolution of dental laboratories will be increasingly based on the use of innovative materials that guarantee qualitatively high level results with repeatability and reliability, without compromises between aesthetic and functional results.
For this reasons, the BTeeth colouring line for the pre-sintered zirconia was developed and produced by Colorobbia Consulting s.r.l., combining ceramics colours know-how with the experience of qualified dental technicians and dental ceramics experts.
BTeeth is a versatile material and, thanks to its structural feature, has an high degree of penetration inside the presintered zirconia, allowing a complete colouring of the prosthetic restoration, avoiding, in case of retouching, pearly not coloured areas.
The main features of the BTeeth colouring line are the deep penetration into the ceramic material and the simultaneous homogeneous diffusion. The penetration and the uniform diffusion of the dye solutions depend on various elements, e.g. the chemical nature of the solutions and the type of substrate used.
The chemical composition of the dough and the baking cycle have influence not only on the penetration but especially on the coloration development.
The colorations of the BTeeth line are based on the presence of metals transition chromophores, that can be present in more than one valence state and this permits that the same chromophore ion can present itself with different colouring.
In the BTeeth series, the innovative process of the colour formation is possible thanks to the "in situ" creation ceramic technology of stable and coloured crystal structures.
This technique has been developing starting from a ten years long experience of Colorobbia Consulting Srl in the field of high temperature ceramic pigments.
It allows the chromophores within the host crystal lattice to generate distortion of the crystal lattice, during the sintering process of zirconia.
Therefore, this event will bring to an electronics bands distortion and finally to the colours creation, that can be "a priori" designed, carefully formulating precursors mixtures.
For these reasons, the BTeeth line is suitable for colouring zirconia in the crystalline tetragonal form.
Actually the developed technique allows to plug appropriate "reagents" cluster into the cavities of the structure, so to give the desired chromatic properties to the material. The products of the BTeeth line are CE certified for their production process, packaging and stability.
