Patent ID: 8501834

Claim:
A dual-curing, multi-component dental composition comprising: (a) one or more photopolymerizable monomers selected from the group consisting of acrylates and methacrylates; (b) one or more photoinitiators, selected from the group consisting of alpha-diketones, benzoin alkyl ethers, thioxanthones, benzophenones, acylphosphinoxides, acetophenones, ketals, titanocenes, borates and sensitizing colorants; (c) one or more molecular weight regulators selected from the group consisting of compounds which can be converted with a radical of a monomer of component (a), wherein the conversion takes place by abstraction of an H-radical from the molecular weight regulator in the allyl position; (d) one or more polymerization inhibitors for increasing the storage stability of the composition; (e) one or more inorganic fillers; (f) one or more initiators for a chemical curing at ambient temperature, and if necessary one or more further additives, wherein: (1) component (c) is present in a quantity of 0.05-5.00 wt. %, in relation to the total mass of the dental composition, (2) component (d) is present in a quantity of 0.005-0.100 wt. %, in relation to the total mass of the dental composition, and/or (3) the ratio of the total mass of component (c) to the total mass of component (d) is in the range of 5:1 to 100:1.
