摘要： The invention relates to a dental cement composition comprising a resin matrix comprising a (meth)acrylate component comprising at least two (meth)acrylate moieties, a polyol spacer group between the at least two (meth)acrylate moieties, the polyols spacer group having a molecular weight Mw of at least 3,000 g/mol, an acidic polymerizable component, preferably an acidic (meth)acrylate component, a non-acidic polymerizable component having a molecular weight Mw below 1,000 g/mol, preferably a non-acidic (meth)acrylate component, filler, an initiator system, optionally additives. The invention also relates to a kit of parts comprising the dental cement composition, a dental crown or a curable dental composition for producing a temporary dental restoration being different from the dental cement composition. The dental cement composition is intended for use in a process of temporarily restoring a dental situation in a mouth of a patient.

摘要： A method of applying a two-part dental sealant is described comprising providing a syringe device (1) comprising a cartridge (10) including first and second chamber. The first chamber contains a first part of a dental sealant comprising a (meth)acrylate resin and an oxidizing curing agent. The second chamber contains a second part of a dental sealant comprising a (meth)acrylate resin and a reducing curing agent that reacts with the oxidizing curing agent of the first chamber. The first and/or second part of the dental sealant further comprise a single component or multiple components that neutralize acid and promote remineralization. The syringe device comprises a dispensing nozzle (17) comprising a static mixer and an outlet at one end of the cartridge and a plunger (20) at the opposing end of the cartridge. Also described is a kit for storing and applying the dental sealant is described.

摘要： Cumene hydroperoxide oligomer according to Formula (I):
in which OLIGOMER is a homo- or copolymer chain, which is substituted n times by the group which is in brackets; Q is absent or is a divalent aromatic C6-C14 hydrocarbon radical or an aliphatic, linear or branched C1-C14 hydrocarbon radical, which can be interrupted by one or more S and/or O atoms and/or —O—CO—NR1— and which can be substituted by one or more substituents; X, Y independently of each other in each case are absent, —O—, —COO—; —CONR3— or —O—CO—NR4—, wherein X is absent if Q is absent, and wherein the substitution on the aromatic compound is effected in position 2, 3 or 4 relative to the cumene hydroperoxide group; and n is a value from 1 to 50.-

摘要： The present invention relates to photopolymerizable resin compositions suitable for producing durable dental prosthetic and restorative articles. In particular, the invention relates to photopolymerizable resin compositions comprised of a specific combination of multiple polymerizable components, one or more resin-modifying particle components, and one or more photopolymerization initiator components. Compositions of the invention are especially well-suited to producing durable, stain-and wear-resistant dental prosthetic and restorative articles, such as artificial teeth, crowns, bridges, inlays, onlays, and veneers, in an efficient and reliable manner using additive manufacturing systems and methods (e.g., three-dimensional (3D) printing).
