Dental material, which contains at least one radically polymerizable monomer, at least one radiopaque filler, at least one composite filler, at least one inorganic filler and at least one initiator for the radical polymerization. The dental material is particularly suitable as dental filling material.

What is described is a milling blank having a continuous shade gradient for production of an indirect dental restoration, composed of resin or a resin-based composite. What is also described is a method of producing such a milling blank by mixing two differently coloured pastes with continuous variation of the mixing ratio of the two pastes during the dispensing operation.

The invention relates to glass-ceramics based on the lithium silicate system which can be mechanically machined easily in an intermediate step of crystallization and, after complete crystallisation, represent a very strong, highly-translucent and chemically-stable glass-ceramic Likewise, the invention relates to a method for the production of these glass-ceramics. The glass-ceramics according to the invention are used as dental material.

Disclosed herein is a ceramic particle comprising a core substrate chosen from yttria-stabilized zirconia, partially stabilized zirconia, zirconium oxide, aluminum nitride, silicon nitride, silicon carbide, and cerium oxide, and a conformal coating of a sintering aid film having a thickness of less than three nanometers and covering the core substrate, and methods for producing the ceramic particle.

Provided are pre-sintered and sintered zirconia dental ceramic materials. The materials have a gradient in yttria content. The materials may have a gradient in one or more physical/mechanical property and/or one or more optical property. The materials may be made by mixing at least two zirconia ceramic powders having different yttria content. A sintered zirconia dental ceramic material may be in the form of a dental article.

The invention relates to a white, bacteria-resistant, biocompatible, adherent coating for an element which can be integrated in hard and soft tissue, in particular an implant, a screw or a plate, having a structure made from metalliferous gradient layers having varying oxygen content, wherein the band gap of the outer-most gradient layer is greater than 3.1 eV, wherein the outer-most gradient layer is crystalline and wherein the gradient layers comprise tantalum and/or niobium and/or zirconium and/or titanium.

The present disclosure is directed to a polymeric layer comprising a catechol containing a monomer, polymer, or oligomer, wherein said catechol presents as a catechol and/or as a semi-quinone and/or as a quinone without the presence of a primary amine or a secondary amine; and wherein the polymeric layer optionally comprises a reactive material that is not reactive with catechol or quinone. The present disclosure is also directed to a polymeric layer comprising a catechol containing monomer, polymer, or oligomer disposed adjacent to and in contact with a bulk adhesive layer. The present disclosure is also directed to methods of coating a substrate using the layers described herein.
