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. ### Claim 2 (depends on 1) The method according to claim 1, wherein the surface to be cleaned is contaminated by proteins. ### Claim 3 (depends on 2) The method according to claim 2, wherein the surface to be cleaned is contaminated by saliva proteins. ### Claim 4 (depends on 1) The method according to claim 1, wherein the cleaning takes place immediately after a try-in of the dental restoration. ### Claim 5 (depends on 1) The method according to claim 1, wherein the metal of the metal compound is selected from aluminium, zirconium, titanium, scandium, yttrium, zinc, ytterbium, cerium and combinations thereof. ### Claim 6 (depends on 5) The method according to claim 5, wherein the metal compound is selected from metal chalcogenides; metal halides; metal chalcogen halides; metal pseudohalides; metal-silicon chalcogenides; metal hydroxides; metal oxyhydroxides, metal nitrates, metal oxynitrates and mixtures thereof. ### Claim 7 (depends on 6) The method according to claim 6, wherein the metal compound is selected from aluminium oxide, aluminium oxide hydroxide, zirconium dioxide, titanium dioxide and mixtures thereof. ### Claim 8 (depends on 1) The method according to claim 1, wherein the carrier medium is a liquid. ### Claim 9 (depends on 1) The method according to claim 1, wherein the particles are present in a quantity of 1 to 50 percent by weight relative to the total weight of the composition. ### Claim 10 (depends on 1) The method according to claim 1, wherein the surface to be cleaned comprises an oxide ceramic, a silicate ceramic, titanium or a titanium alloy. ### Claim 11 (depends on 1) The method according to claim 1, wherein the particles have a weight-average particle diameter of 1 to 100 nm. ### Claim 12 (depends on 1) The method according to claim 1, wherein the carrier medium is a solid. ### Claim 13 (depends on 1) The method according to claim 1, wherein the particles are present in a quantity of 5 to 35 percent by weight relative to the total weight of the composition. ### Claim 14 (depends on 1) The method according to claim 1, wherein the particles of the composition bond to proteins in the bodily fluids for removal from the surface. ### Claim 15 (depends on 14) The method according to claim 14, wherein the bond comprises adsorption, ionic bonding and/or covalent bonding. ### Claim 16 A method for cleaning dental materials, 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 applying is performed by stirring the metal or ceramic surface in the composition or contacting the metal or ceramic surface with a brush; 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. ### Claim 17 (depends on 1) The method according to claim 1, wherein the securing step comprises adhesion by one or more of an adhesive promoter, a cement, or a composite. ### Claim 18 (depends on 17) The method according to claim 17, wherein the adhesive promoter comprises a self-adhesive and/or a primer. ### Claim 19 (depends on 16) The method according to claim 16, wherein the securing step comprises adhesion by one or more of an adhesive promoter, a cement, or a composite. ### Claim 20 (depends on 19) The method according to claim 19, wherein the adhesive promoter comprises a self-adhesive and/or a primer.
