    摘要: Presently described are dental adhesive compositions and methods of use. The dental adhesive compositions described herein comprises a major amount of a hardenable component comprising a polymerizable organic component (i.e. having ethylenically unsaturated moieties) and a minor amount of a (e.g. water dispersible) polymer that comprises repeating units comprising polar or polarizable groups and repeating units comprising hydrophobic hydrocarbon groups.

    摘要: The invention features dental compositions comprising at least one hybrid monomer that comprises a cyclic allylic sulfide moiety attached to a (meth)acryloyl moiety. These two functional moieties are typically joined either directly to each via a chemical bond or through some chemical structure or spacer molecule. The composition may optionally contain additional polymerizable compounds, such as ethylenically unsaturated compounds, that are typically used in dental compositions.

    摘要: A digital painting process provides computer-controlled finishing of dental articles. The process can selectively apply different materials over portions of a dental article in one or more layers to achieve a multi-chromatic finish having a variety of colors, finishes, and surface properties that closely match the appearance and function of human dentition.

    摘要: An apparatus for dispensing a predetermined quantity of a multi-component composition in which the composition includes a first component and a second component in a predetermined weight to weight ratio, and in which the first component and said second component undergo an undesirable chemical reaction with each other when brought into contact with each other. The apparatus includes a receptacle for storing one of the first component or the second component that is adapted to receive the other of the first component or the second component from a separate source to form the predetermined quantity of multi-component composition having the first component and the second component in a predetermined weight to weight ratio.

    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 photoinitating 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.
