The present invention relates to oral care and dental implants. In particular, the present invention is a dental implant with a removable protective film that is used to prevent implant loss and remove unwanted residual cement.

The present invention provides dental bonding agents and dental bonding systems comprising the dental bonding agents. The dental bonding agents of the invention are characterized by having antibacterial properties, and in some aspects of the invention, remineralizing properties.

A method of smoothing teeth is disclosed, the utility of which is based on surprising empirical evidence achieved via practice of a method involving application of calcium thereto and maintaining it in contact therewith by application of a composition of matter that adheres to said teeth.

The present invention relates to: composition for differentiating non-dental mesenchymal stem cells into odontoblasts comprising CPNE7 protein or gene; method for differentiating in vitro non-dental mesenchymal stem cells using the same; and also use thereof.

Methods, devices and systems are disclosed for chemically bonding antibiotics to selected substrate materials which are not dissolved in normal physiological processes so that high local concentrations can be achieved during the inflammatory response. The antibiotics will remain permanently bonded to the substrate material until an infection occurs which releases the antibiotic in high concentrations to help control the infection. The high local concentrations may be much higher than systemic toxic levels, and can never reach toxic levels because the local dose is much less than needed to reach systemic toxicity if completely dissolved.

A bone cement formulation comprising: (a) magnetic calcium phosphate nanoparticles present in an amount of 5.0-95 wt. % and having a largest linear dimension of 150 nm to 50 microns; (b) polymerizable acrylate monomer present in an amount of 5.0-95 wt. %; and (c) polyacrylate polymer present in an amount of 0-80 wt. % and having a largest linear dimension from 5.0 to 500 microns. Upon exposure to an alternating magnetic field the formulation is heated which results in polymerization of the acrylate monomer component. The formulation may also be polymerized via the use of chain polymerization initiators.

Provided is a dental glass ionomer cement composition whose hardened cement has a high strength, despite not including a (meth)acrylate monomer. The dental glass ionomer cement composition includes a filler in which a compound(s) having a carboxyl group(s) is/are bound to a surface of an inorganic powder via a silicon atom, the composition not including a (meth)acrylate monomer.

Non-aqueous hydraulic cement compositions comprise a non-aqueous mixture of (a) a non-hydrated powder composition comprising calcium silicate powder or calcium aluminate powder, and (b) non-aqueous water-miscible liquid. Hardened cements are formed from such hydraulic cement compositions, and methods of producing hardened cements, kits, and articles of manufacture employ such hydraulic cement compositions.

Provided are dental articles, and methods of making articles, having an aesthetic inorganic coating based on zirconia at least partially stabilized with yttrium oxide, calcium oxide, cerium oxide, or magnesium oxide. Stabilized zirconia coatings were found to provide a smooth, low friction surface having high abrasion resistance. These coatings are particularly applicable to orthodontic appliances. While virgin stabilized zirconia coatings can often have an undesirable color cast, it was discovered that this color cast can be substantially eliminated by heat treating the coated appliance in an oxygenated environment. The combination of depositing a stabilized zirconia coating and subsequently heat treating to decolorize the coating provides a surprisingly robust, stable, low-friction coating that is also aesthetic.
