Abstract
The invention relates to a solution to be selectively applied to individual parts of the surface of dental ceramic(s) and a process for using the solution in the dental field. More specifically the invention relates to a solution comprising a) a solvent, b) an effect agent, and c) a complexing agent. The invention also relates to a kit comprising the solution and to a method of using the solution for selectively treating of parts of the surface dental ceramic(s). The invention also relates to a application instrument suitable for applying the solution.
Claims16
A non-water based solution for selective application to parts of the surface of a dental ceramic, the solution comprising
- a solvent being miscible with water but not being water,
- an effect agent comprising metal ions, the effect caused by the effect agent being either colouring, providing fluorescence or a combination thereof
- a complexing agent being able to form a complex with the metal ions of the effect agent, wherein the complex is soluble in the solvent,
- the non-water based solution having a viscosity above about 200 mPa*s at 23° C.,
- wherein the water-content of the solution is below about 10 wt.-% with respect to the whole composition.
