Abstract
A composition, containing a carrier medium and particles based on a metal compound with a weight-average particle diameter of 1 nm to 10 μm is useful to clean metal or ceramic surfaces which are part of a dental restoration or of an implant abutment.
Claims20
A method for cleaning dental materials contaminated with bodily fluids, comprising steps in the following order:
- inserting a dental restoration into a tooth cavity, onto a tooth stump or onto an implant abutment in an oral cavity to check accuracy of fit;
- removing the dental restoration from the oral cavity;
- applying a composition onto a metal or ceramic surface of the dental restoration, wherein the composition comprises 1 to 75 wt.-% particles with a weight-average particle diameter of 1 to 500 nm based on a metal compound which is selected from metals of the 3rd main group, subgroup metals and lanthanoids of the Periodic Table, and 25 to 99 wt.-% water or aqueous solution with a pH in the range from at least 8 to 14, wherein the particles of the composition interact with phosphate groups of the bodily fluids;
- rinsing the surface with water to remove the composition, and
- securing the metal or ceramic surface to the tooth cavity, tooth stump, or implant abutment located in the oral cavity.
