Low viscosity composites, with a flexural modulus of at least 18 GPa and a flexural strength of at least 90 MPa for filling dental root canals for fixing post or as a build-up material on post, are composed of aluminum oxide with a mean particle size of 1 to 50 &#x3bc;m in combination with at least one additional filler with a mean particle size of 0.5 to 5 &#x3bc;m and a monomer mixture. Also disclosed is a method for the preparation of tooth restorations.

Dental materials with a high flexural modulus

Slip for use in a hot-melt inkjet printing process which contains (A) ceramic particles, (B) wax and (C) at least one radically polymerizable monomer, and use of the slip to prepare dental restorations. Furthermore, a process for the preparation of a green compact is described, in which the slip is molded in layers to the geometrical shape of the green compact and subjected to a radical polymerization in order to obtain a cured green compact.
