Compositions are used for coating teeth and dental prostheses based on a mixture of (a) at least one compound that is soluble in the reaction medium having the formula (I) MRx (I) in which M means Ti, Zr, Si, Ge, Sn or Al, R means halogen, hydroxy, alkoxy, acyloxy or a chelate ligand, and x means th
Compositions are used for coating teeth and dental prostheses based on a mixture of (a) at least one compound that is soluble in the reaction medium having the formula (I) MRx (I) in which M means Ti, Zr, Si, Ge, Sn or Al, R means halogen, hydroxy, alkoxy, acyloxy or a chelate ligand, and x means the valency of M, and (b) an organic silane having the formula (II) R″nSiX4-n (II) in which R″means alkyl, alkenyl, aryl, arylalkyl, alkylaryl, arylalkenyl or alkenylaryl, where said radicals may be interrupted by oxygen or sulfur atoms or －NH－groups, X means hydrogen, halogen, hydroxy, alkoxy, acyloxy or the group －NR2′(R′=hydrogen and/or alkyl) and n has the value 1, 2 or 3, and/or (c) an organofunctional silane having the formula (III) Rm″(R″′Y)nSiX(4-m-n) (III), in which R″, X and n have the meaning given above, R″′means alkylene, phenylene, alkylene phenylene or alkenylene, where said radicals may be interrupted by oxygen or sulfur atoms or －NH－groups, Y means halogen atoms, hydroxy, mercapto, polyol, e.g., glycyl or glyceryl, optionally substituted amino, quaternary ammonium, amide, polyamide, aldehyde, keto, carboxy, carboxylic acid alkyl ester, sulfonic acid, phosphoric acid, epoxy, acryloxy or methacryloxy groups and m has the value 1, 2 or 3. The coatings are resistant to plaque deposits.
