Abstract: An implant system including a dental implant and an abutment produced from a ceramic material, wherein the abutment includes a first anti-rotation element with multiple grooves and the dental implant includes a second anti-rotation element, which is complementary thereto, with multiple ribs, wherein the grooves are open toward a proximal end of the abutment.

Abstract: Molding or coating materials, in particular coating substances for producing self-cleaning moldings or coatings, for example on facades and other building elements, which if they are exposed to rain or moving water from time to time, clean themselves and prevent permanent settlement of dirt particles and pollutants. In accordance with the invention that object is attained with molding or coating materials having the features set forth in the opening part of this specification, which are characterized in that the filler contained has an at least bimodal particle size distribution, wherein the one particle size range (A) has a mean particle diameter of at least 5 ?m and the other particle size range (B) has a mean particle diameter of at most 3 ?m and the weight ratio of the particles of the former particle size range (A) to the particles of the latter particle size range (B) is between 0.
