Polymerizable dental material

In an improved polymerizable dental material of the type containing monomeric (meth)acrylate, a finely divided inorganic filler, and a polymerization catalyst, the improvement wherein

• the inorganic filler consists essentially of 5 to 100% by weight of finely divided synthetic crystalline silicic acid with a sheet structure and of 0 to 95% by weight of very finely ground glass;
• wherein
• the finely divided silicic acid having a sheet structure, has a particle size distribution ranging from 1 to 40 .mu.m and a mean particle size of approximately 4 .mu.m;
• the very finely ground glass has a particle size distribution ranging from 0.1 to 5 .mu.m and a mean particle size of approximately 0.7 .mu.m;
• and
• the finely divided silicic acid has an overall composition H.sub.2 Si.sub.x O.sub.2x+1, wherein x denotes a number between 15 and 24, which exhibits a very strong first line in the X-ray diffraction pattern at (3.42.+-.0.1).multidot.10.sup.-8 cm and a further line at (18.+-.4).multidot.10.sup.-8 cm, the intensity of which is not more than 75% of the intensity of the first line, and which has a titratable acidity of 83 to 130 mmol of H+/mol of SiO.sub.2.
