Classification: CPC A | IPC A

Claim 0:
1. A photocurable dental impression material comprising:
(a) a mixture of polymerizable silicone compounds each having two or more polymerizable (meth)acrylate groups, said mixture having a dynamic viscosity at 25° C. of from 1 to 100 Pas;
(b) a filler;
(c) a photo initiator system,
wherein the mixture of polymerizable silicone compounds comprises based on the total weight of the mixture of polymerizable silicone compounds
(i) 10 to 90 percent by weight of high-molecular polymerizable silicone compounds having a molecular weight in the range of from more than 4000 up to 10,000; and
(ii) 90 to 10 percent by weight of polymerizable silicone compounds having a molecular weight in the range of from 300 to 4000,

wherein a ratio of (meth)acrylate groups per total molecular weight of the polymerizable silicone compounds of (ii) is higher than a ratio of (meth)acrylate groups per total molecular weight of molecules of the high-molecular weight polymerizable silicone compounds of (i).
