  • Patent number: 10512526
    Abstract: A dental coloring stamp has a transfer pad for transferring a dental coloring solution to a precursor of a dental restoration. The transfer pad is at least partially formed of an open-celled elastic sponge and has a free transfer surface. The cross-section of the transfer pad is greater than a circular area of 10 mm in diameter so that a side of a dental restoration precursor can be stamped and thus colored. The invention helps facilitating the coloring of dental restorations.

  • Publication number: 20190247152
    Abstract: The invention relates to a process for selectively treating parts of the surface of a porous dental zirconia article, the process comprising the steps of providing a liquid composition and a porous 3-dimensional dental zirconia article having an outer and inner surface, applying the liquid composition to only a part the outer surface and/or inner surface of the porous dental zirconia article, the liquid composition comprising a whitening agent comprising a phosphorous containing component, the phosphorous containing component comprising a phosphate, phosphone or phosphine moiety, with the proviso that at least one P-O unit of the phosphate, phosphone or phosphine moiety is dissociable or able to otherwise interact with zirconia. The invention also relates to a dental zirconia article obtainable or obtained by such a process and a kit of parts comprising a container containing a certain liquid composition and a dental zirconia mill blank useful for producing a porous dental zirconia article.

  • Patent number: 10219880
    Abstract: Disclosed herein a dental mill blank and a method of forming the dental mill blank. The dental mill blank includes a first layer of a first hard restorative material having a first translucency and a first shade, a second layer of a second hard restorative material having a second translucency and a second shade, where at least one of the following is true (1) the first translucency is different from the second translucency, (2) the first shade is different from the second shade. The first layer and the second layer form a first interface having a first curve across a first plane of symmetry of the dental mill blank, where the first curve has a different from zero curvature; and a first straight line along the entire length of a second plane of the dental mill blank, the second plane being orthogonal to the first plane of symmetry.

  • Publication number: 20160228222
    Abstract: The present disclosure provides for a dental mill blank and a method of forming the dental mill blank. The dental mill blank includes a first layer (102) of a first hard restorative material having a first translucency and a first shade, a second layer (104) of a second hard restorative material having a second translucency and a second shade, where at least one of the following is true: the first translucency is different from the second translucency, the first shade is different from the second shade. The first layer (102) and the second layer (104) form a first interface having a first curve (112) across a first plane of symmetry (114) of the dental mill blank, where the first curve (112) has a different from zero curvature; and a first straight line (122) along the entire length of a second plane (118) of the dental mill blank, the second plane (118) being orthogonal to the first plane of symmetry (114).

  • Patent number: 8141384
    Abstract: A molding operation produces an extractor array by providing a mold having a plurality of cavities therein, each cavity being adapted to form an extractor suitable for coupling to an LED die; filling the mold with a plurality of glass particles; heating the glass particles above glass transition temperatures thereof so that the particles are reshaped to conform to the cavity shapes; and forming a land layer that extends between the cavities. The land layer maintains the extractors in a fixed spatial relationship with each other for subsequent handling or processing, such as a simultaneous polishing operation or in attaching the extractor array to a corresponding LED array.

  • Patent number: 8026115
    Abstract: Disclosed herein is an optical bonding composition that may be used in optical applications. An LED light source that utilizes the composition is also disclosed, as well as a method of making it. The LED light source may comprise: an LED die; an optical element optically coupled to the LED die; and a bonding layer comprising surface-modified metal oxide nanoparticles in an amorphous silicate network, the bonding layer bonding the LED die and the optical element together. Efficiency of the LED light source may be increased when using an optical extractor as the optical element.
