Abstract: The invention concerns a dental composition comprising bisacrylamides that are polymerizable by free-radical polymerization and by Michael-addition polymerization with amines. The application of polymerization and addition polymerization with amines opens the possibility to completely reacted materials that have no oxygen inhibited layers. The claimed bisacrylamides have an improved hydrolytic stability.

Abstract: The invention describes a low shrinking polymerizable dental material, comprising a mixture of a polymerizable resin, a polymerizable monomer, a polymerization initiator and/or sensibilizer and a filler in a content of about 20 to about 85 percent. The volumetric shrinkage during polymerization is less than about 1.5 Vol.-% due to its rheopex behavior.

Abstract: Dental compositions comprising at least a polymerizable monomer and/or at least a polyaminoester that are prepared by reaction of bis- or polyacrylic esters and amines, pigments, organic and/or inorganic fillers, initiators and stabilizers.

Abstract: The invention concerns macromonomers of a molecular weight of at least M≧500 g/mol containing siloxane groups. The macromonomers are usable as polymerizable monomers in a dental/medical composite comprising further at least a polymerizable monomer, an organic or inorganic acid or an acidic monomer, a stabilizer, an initiator, pigments and an organic or inorganic filler. The dental/medical composite is usable as a dental restorative material for filling and restoring teeth, making inlays and onlays, for artificial teeth, for sealing and surface modification materials, usable as temporary crown and bridge material. Furthermore, the macromonomers are usable for filler surface modification, as precursors for siloxane condensation products or as precursor for preparation of nanoparticles containing active polymerizable moieties.

Abstract: Dental root canal filling cones are prepared from a filler and a thermoplastic polymer, wherein the thermoplastic polymer is formed by polymerization of polymerizable diepoxide monomer and amine monomer. The amine monomers are primary monoamine and/or a disecondary diamine. The filler has about 40 to 90 weight-% of the cones providing a radio-opacity of at least 3 mm/mm aluminum.

Abstract: A method of venting during sealing the cartridge. The cartridge body has an external wall, a generally cylindrical internal chamber wall having an internal chamber wall diameter and enclosing a cartridge chamber, and at least one channel wall forming a channel (or groove) in the chamber wall. The piston has a generally cylindrical plug wall positioned adjacent to the generally cylindrical internal chamber wall. The cylindrical plug wall has a diameter substantially equal to the diameter of the cylindrical internal chamber wall. Dental material is conveyed into the cartridge chamber. The piston is pressed into the cartridge chamber while venting gas from the cartridge chamber through the channel prior to forming a hermetic seal around the dental material in the cartridge chamber.

Abstract: The synthesis of self-adhesive polymerizabe monomers and their application as a water containing and a water free self-adhesive dental/medical composite is described. The dental/medical composite comprises a self-adhesive polymerizabe monomer, a polymerizable monomer, an acid-reactive and/or reactive and/or non-reactive filler, a diluent, a polymerization initiator and a stabilizer. As polymerization initiators are used the commonly known thermal initiators, redox initiators and/or photo initiators. The new adhesive dental composite develops adhesion to dentine of about 4 MPa. Fillers of high X-ray absorbance provide radio-opacity values grater than that of the same thickness of aluminium.
