A dental prosthesis to be integrated into a jaw bone cavity of a pre-identified patient. An example of a dental prosthesis includes a first manufactured portion having a surface shaped to substantially dimensionally conform three dimensionally to an undersized shape of the outer three-dimensional surface shape of a root of a tooth to be replaced, and a second manufactured portion shaped to substantially conform to the three-dimensional surface of a crown of the tooth. The outer surface of the root portion can include or be coated with a biocompatible material that is suitable to be integrated into the extraction socket and adopted by existing tissue forming the socket.

Antimicrobial polymer composite materials are disclosed that are suitable for making oral devices used in dental applications, such as denture bases. Acrylic resin composite materials comprising antimicrobial polymers and antimicrobial fillers provide reduction in common oral microorganisms after long-term aging, with reduced release rate of antimicrobial agents from the composite material. Antimicrobial polymers are prepared from compositions comprising acrylate and/or methacrylate monomers and polymerizable quaternary ammonium silicon-containing compounds.

The present invention provides a dental composition that exhibits excellent long-lasting antibacterial activity even as a cured product, and that excels in aesthetic quality with no discoloration occurring in water or in hydrogen sulfide. The present invention relates to a dental composition comprising a platinum nanoparticle (a) uncoated with a colloidal protective material.

A medical device or solution for treating dental discomfort by at least partially occluding dental tubules is disclosed. The medical device or solution contains a polysaccharide or other biocompatible polymer with an antimicrobial metal, antimicrobial metal compound, or antimicrobial metal ion bound to a biopolymer. The medical device or solution further comprises at least one soluble antimicrobial. The soluble antimicrobial may be a water soluble metal iodide, water soluble metal fluoride, or a water soluble metal chloride encompassed with the nanogel. The medical device may be a solution of a chitosan with a nanoparticle of silver fluoride on the chitosan and at least one of a sodium fluoride or silver fluoride. The solution may be water based solution. Methods of applying the medical device or solution are also disclosed.

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.

A curable composition comprises at least one monomer comprising at least one (meth)acryl group and a photoinitiator system. The photoinitiator system comprises at least one Type II photoinitiator and at least one cyclic β-diketone represented by the formula (I) or a tautomer thereof. R.sup.1 represents an organic moiety having at least one free-radically polymerizable group. Each R.sup.2 independently represents H or an aliphatic group having from 1 to 12 carbon atoms, and up to two of oxygen and sulfur atoms, n represents 1, 2, or 3.

Curable compositions comprise at least one (meth)acrylate monomer; silver; and a photoinitiator system. The photoinitiator system comprises at least one cyclic β-diketone represented by the formula (I) or a tautomer thereof, wherein: R.sup.1 represents H or an organic moiety having from 1 to 32 carbon atoms and optionally 1 to 12 heteroatoms selected from O, N, and combinations thereof; each R.sup.2 independently represents H or an aliphatic group having from 1 to 12 carbon atoms, and up to two of oxygen and sulfur atoms; and n represents 1, 2, or 3; and at least one Type II photoinitiator. Methods of making and using the compositions are also disclosed.

A single and dual component dental composite restorative featuring anti-microbial and low Coefficient of Thermal Expansion (CTE) compounds is disclosed. The exemplary anti-microbial compound is zinc oxide. The CTE of the dental composite restorative is the same as, or substantially similar, to that of dentin. By maintaining a CTE substantially similar to that of dentin, the Margin Percolation phenomenon is minimized, which decreases the incidence of secondary caries.

A family of cobalt based dental alloys suitable for PFM and SLM applications that do not exhibit ferromagnetism and that are capable of meeting the ADA requirements for a “noble” alloy are provided. The dental alloys comprise at least 25 wt. % of noble metals selected from either platinum alone or a combination of platinum and ruthenium, and from 23 to 32 wt. % chromium. Additional additive materials may be included in concentrations up to 3 wt. %. The ruthenium optionally comprises up to 8 wt. %, and in some embodiments from at least 5 wt. % to 8 wt. % of the noble metals such that the dental alloys are capable of meeting the ADA requirements for a “noble” alloy.
