A dual-curing, multi-component dental composition comprising: (a) one or more photopolymerisable 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, acyl phosphine oxides, acetophenones, ketals, titanocenes, borates and sensitising dyes, (c) one or more molecular weight regulators selected from the group consisting of compounds that can be reacted with a radical of a monomer of component (a), wherein the reaction takes place with abstraction of an H radical from the molecular weight regulator in the allyl position, and wherein one or more of the molecular weight regulators of component (c) are compounds with two or more double bonds, which, through abstraction of an allyl H atom, can form a delocalised electron system extending across 5 or more C atoms, and are selected from the group of the monoterpenes α-terpinene, β-terpinene, γ-terpinene, α-phellandrene, β-phellandrene and terpinolene or are selected from the group consisting of linoleic acid, linolenic acid and other substituted or non-substituted cyclohexadienes, (d) one or more polymerisation inhibitors for increasing the storage stability of the composition, selected from the group consisting of hydroquinone monomethyl ether (HQME), 2,6-di-tert.-butyl-4-methylphenol, tert.-butylhydroxyanisole, 2,2-diphenyl-1-picrylhydrazyl radicals, galvinoxyl radicals, triphenylmethyl radicals, 2,3,6,6-tetramethylpiperidinyl-1-oxyl free radical (TEMPO) and phenothiazine, (e) one or more inorganic fillers, (f) one or more initiators for chemical curing at ambient temperature and optionally one or more further additives.
