摘要: Substituted saccharide compounds, dental compositions comprising substituted saccharide compounds, and methods of using dental compositions are described. In one embodiment, the substituted saccharide amide compound comprises a hydrophobic group and at least one free-radically polymerizable group with the proviso that the hydrophobic group is not bonded to the ethylenically unsaturated carbon atom of the free-radically polymerizable group. The hydrophobic group is typically bonded to a nitrogen atom of a saccharide amine residue or a carbonyl moiety of saccharide amide residue.

摘要: A dental article is fabricated from an SMC material using three-dimensional data captured from natural dentition to guide a computer-controlled milling machine. The three-dimensional data may include scans of an original tooth structure and a prepared tooth surface to characterize all surfaces of a dental article, or certain features may be created within a computer-assisted design environment taking account of occlusion, proximal contacts, and the like. In addition the model applied to a computer-controlled milling machine may account for shrinkage of the SMC material during any post-milling curing steps in order to ensure an accurate fit to the prepared tooth surface.

摘要: Resin-modified glass ionomer cements contain a polymer having a plurality of acidic repeating units but being substantially free of polymerizable vinyl groups, a polymer having a plurality of acidic repeating units and a plurality of polymerizable vinyl groups, a fluoroaluminosilicate glass, a redox cure system that can initiate dark cure of the vinyl groups, and water. The cements can be used without requiring a preliminary tooth priming or conditioning step and without requiring a curing lamp. The cements offer ease of mixing, convenient viscosity, convenient cure, good flexural strength, good adhesion to dentin and enamel, and high fluoride release, even when cured in thick sections and in the dark.

摘要: The invention provides a two-part adhesive composition making it possible to mutually bond disk substrates within a relatively short time and to produce an optical disk, and an optical disk having a metal film, corrosion of which is restricted under a high-temperature high-humidity condition, and which is produced by using the two-part adhesive composition. A two-part adhesive composition of the invention comprises first and second parts each containing urethane acrylate having a polytetramethylene glycol skeleton and an acrylate having a hydroxyl group in its molecule, wherein the first part further contains a diacyl peroxide and the second part further contains a tertiary amine. Organic peroxide is preferably diacyl peroxide and a setting promoter is preferably a tertiary amine. Either one, or both, of the first and second parts may further contain a photo-polymerization initiator.

摘要: A photosensitive composition is prepared containing a polymer of the formula B(X)(Y) wherein B represents an organic backbone, each X independently is an acidic group or salt thereof and each Y independently is a photocurable group and a photoinitiating compound or compounds. Preferably, free-radically polymerizable multi-functional monomer and/or oligomer is added to the photosensitive composition. The photosensitive composition can be coated on a suitable substrate for planographic printing plate applications. Imagewise irradiation causes the light struck regions to photocure, becoming insoluble in aqueous and organic mediums, while the non-light struck regions remain highly soluble/dispersable. Printing plates of this construction do not require processing prior to being run on a press.
