  • Patent number: 8636928
    Abstract: The invention provides methods of making provisional and long-term dental restorations, particularly dental veneers, implants, crowns and bridges. A shell or restoration form made of polymerizable material having good dimensional shape-stability in its uncured condition is used to make the dental restoration. A polymerizable material is introduced into the cavity of the shell form. The outer shell and injected polymerizable material are polymerized and bond together to form a hardened crown structure. In one embodiment, the restoration can be fabricated indirectly by a dental laboratory. In another version, a dental practitioner can make the restoration chairside for a patient in a dental office.

  • Patent number: 8616873
    Abstract: A micro-conformal nanoimprint lithography template includes a backing layer and a nanopatterned layer adhered to the backing layer. The elastic modulus of the backing layer exceeds the elastic modulus of the nanopatterned layer. The micro-conformal nanoimprint lithography template can be used to form a patterned layer from an imprint resist on a substrate, the substrate having a micron-scale defect, such that an excluded distance from an exterior surface of the micron-scale defect to the patterned layer formed by the nanoimprint lithography template is less than a height of the defect. The nanoimprint lithography template can be used to form multiple imprints with no reduction in feature fidelity.

  • Patent number: 8580183
    Abstract: Methods of producing collection tubes are presented. The methods include providing a separator substance that can rapidly polymerize in a short time to a desired hardness and disposing the separator substance within the lumen of the tube. The separator substance is formulated to have a density between an average density of a serum fraction of whole blood and a cell-containing fraction of whole blood, and to be flowable with whole blood. Upon centrifugation of a tube having blood, the separator substance forms a barrier between the whole blood fractions. The barrier rapidly hardens forming a solid barrier when triggered by a suitable energy source.
