PROBLEM TO BE SOLVED: To improve a dental material at least by eliminating defects in dental materials of well-known technical level. SOLUTION: The dental material with a high abrasion resistance comprises (a) 20-50% of a monofunctional methacrylate/arylate, (b) 1-20% of a crosslinkable methacrylate/acrylate, (c) 2-30% of a ground down polymer of the component (b) and a component (e), (d) 2-50% of partially crosslinked PMMA (polymethyl methacrylate)-beads polymer, (e) 0-20% of pyrogenic silica obtain by silanisation method, (f) 5-50% of inorganic reinforced beads polymer, (g) 0.1-1% of a reaction initiator and (h) 0.1-3% of a coloring pigment.
