<p>Dual-curing, multi-component dental composition comprises (a) at least one photopolymerizable monomer, (b) at least one photoinitiator, (c) at least one molecular weight regulator, which is reacted with a radical of a monomer of the component (a), where the reaction is carried out by abstracting a hydrogen-radical in allylic position, (d) at least one polymerization inhibitor for increasing the storage stability of the composition, (e) at least one inorganic filler, (f) at least one initiator for chemical curing at ambient temperature, and optionally at least one additional additive. Dual-curing, multi-component dental composition comprises: (a) at least one photopolymerizable monomer comprising acrylate and methacrylate, preferably methacrylate; (b) at least one photoinitiator comprising alpha -diketones, benzoin alkyl ethers, thioxanthones, benzophenone, acylphosphine oxides, acetophenone, ketals, titanocene, borates or sensitizing dyes; (c) at least one molecular weight regulator comprising a compound that can be reacted with a radical of a monomer of the component (a), where the reaction is carried out by abstracting a hydrogen radical from the molecular weight regulator, present in allylic position; (d) at least one polymerization inhibitor for increasing the storage stability of the composition, comprising hydroquinone monomethyl ether, phenol, preferably 2,6-di-tert-butyl-4-methylphenol or tert-butyl hydroxyanisole, 2,2-diphenyl-1-picrylhydrazyl-radical, galvinoxyl-radical, triphenylmethyl-radical, 2,3,6,6-tetramethyl piperidinyl-1-oxyl-radical or their derivatives or phenothiazine or its derivatives; (e) at least one inorganic filler; (f) at least one initiator for chemical curing at ambient temperature, preferably a redox initiator system; and optionally at least one additional additive. Independent claims are also included for: (1) a dental syringe, preferably a dual-chamber syringe or a dual-chamber cartridge with mixing attachment comprising the dental composition; and (2) producing the dental composition, comprising producing a multi-component, preferably two-component system comprising the components (a), (b), (c), (d), (e) and (f) and optionally further additives, where the initiators of the component (f) are distributed in separate components of the dental composition, such that a chemical initiation is caused by mixing of the components.</p> |
