Verwendung einer Zusammensetzung, enthaltend ein Trägermedium und Partikel auf der Basis einer Metallverbindung mit einem gewichtsmittleren Teilchendurchmesser von 1 nm bis 10 µm zur Reinigung von Oberflächen aus Metall oder Keramik, die Teil einer Dentalrestauration oder eines Implantatabutments sind.Cleaning dental materials comprises: contacting a composition containing a carrier medium and particles based on a metal compound having a weight-average particle diameter of 1 nm to 10 mu m, with a metal or ceramic surface, which is part of a dental restoration or of an implant abutment and moving the composition on the surface. Independent claims are also included for: (1) restoring a tooth comprising: inserting a dental restoration into a tooth cavity, onto a tooth stump or onto an implant abutment to check the accuracy of fit optionally, removing the dental restoration from the oral cavity intra- or extra-orally cleaning the dental restoration and/or intra-orally cleaning the implant abutment, by the method of cleaning dental materials and adhesively fixing the dental restoration in the oral cavity in the tooth cavity, on the tooth stump or on the implant abutment and (2) cleaning composition comprising: particles based on a metal compound (5-35 wt.%) water or aqueous solution (65-95 wt.%) with a pH of 7-14 and optional constituents (0-5 wt.%).
