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.

First claim

What is claimed:

1. A cleaning composition for dental materials, comprising
(i) 5 to 35 wt. % zirconium dioxide particles with a weight average particle diameter of 1 to 100 nm,
(ii) 65 to 95 wt. % water or aqueous solution with a pH in the range from 11 to 14, and
(iii) 0 to 5 wt. % optional constituents,
wherein the dental materials comprise a metal or ceramic surface, wherein the particles of the composition interact with phosphate groups on the metal or ceramic surface to be cleaned and wherein the cleaning composition is free of detergents and bleaching agents.

2. The cleaning composition according to claim 1 , wherein the surface to be cleaned comprises an oxide ceramic, a silicate ceramic, titanium or a titanium alloy.

3. The cleaning composition according to claim 1 , wherein the particles are present in a quantity of 10 to 30 wt.-% relative to the total weight of the composition.

4. The cleaning composition according to claim 1 , wherein the surface to be cleaned is contaminated by proteins.

5. The cleaning composition according to claim 4 , wherein the surface to be cleaned is contaminated by saliva proteins.

6. The cleaning composition according to claim 1 , wherein the surface is cleaned immediately after a try-in in a patient's mouth.
