  • Patent number: 11426332
    Abstract: The invention is related to a shaded porcelain system that contains two types of veneering porcelains: natural enamel/dentin body and opal enamel, as well as stain & glaze porcelain, with CTE that are compatible to and which can be used for veneering a dental prosthesis made of 1) lithium disilicate-based glass-ceramic substructure that is formed by hot pressing or CAD/CAM machined process or 2) YTZP zirconia-based ceramic substructure that is formed by CAD/CAM machined process in order to improve overall esthetics of final prosthesis.

  • Patent number: 10603144
    Abstract: A dental prosthesis, typically formed in a press to metal process, includes application of a porcelain composition sufficient to form a veneer on a dental prosthesis supporting metal structure, the composition having an integrated tooth-like translucency providing an aesthetic appearance. The composition is formed of a dentin frit and an enamel frit, typically sintered into a desired ingot shape including an amount of composition sufficient to veneer the prosthesis. The porcelain composition is a component of a kit that includes opaquers, other porcelains and stains useful in finishing to provide an aesthetic prosthesis.

  • Publication number: 20190038387
    Abstract: An integrated dental porcelain system for making dental prostheses and restorations is provided. The system includes three universal major components: a) opaque porcelain composition; b) pressable dentin ingot; and c) veneering porcelain composition that can be used interchangeably for making restorations. Techniques for making the prostheses and restorations include porcelain fused-to-metal (PFM), press-to-metal (PTM), and either pressed and/or machined all-ceramic methods. The system uses both a hand-layering of veneering porcelain (PFM technique) and a hot-pressing process (PTM and all-ceramic technique) to fabricate the prostheses and restorations.

  • Patent number: 8052424
    Abstract: A series of ceramic ingots is provided in which each ingot in the series, referred to as base ingots, has a shade corresponding to a different shade of a shade guide. The number of differently shaded base ingots is less than the total number of shades associated with the shade guide. A base ingot is selected from the series having a shade of a value at least as high as a shade associated with a patient's tooth. If the base ingot shade matches the patient's tooth, a restoration made with the selected base ingot can be glazed as is; otherwise the dental restoration is stained with a stain having a lower value than the selected base ingot to match the tooth. Thus, the total different number of ingot shades needed in inventory is reduced but without requiring staining in every case.
