A two-component dental material addition-crosslinking by way of hydrosilylation contains (a) one or more compounds having vinyl groups in the molecule, (b) at least one organohydrogen silicone compound, and (c) at least one catalyst. The at least one compound (a) and/or the at least one compound (b) includes as the first structural unit, at least one voluminous and/or rigid group, and as the second structural unit, at least two alkenyl-functional or at least two hydrogen-functional silyl units. The second structural unit is bound to the first structural unit (i) directly, (ii) by way of an oxygen atom, (iii) by way of a spacer group, or (iv) by way of a spacer group according to (iii), which is bound to the first structural unit by way of an oxygen atom.
