The present invention relates to a dental composition comprising a radically polymerizable compound, a redox initiator system comprising one or more clathrate compounds comprising a host molecule and one or more guest molecules, wherein the host molecule is selected from cyclodextrines, crown ethers, cucurbituriles and calixarenes and the one or more guest molecules are reducing agents, and an oxidizing agent. Furthermore, the present invention relates to a use of the redox initiator system in a dental composition.

A method for promoting spine fusion inside intersomatic cages, comprising placing a fusion cage between two vertebral bodies, and injecting a bone cement paste inside said fusion cage, said bone cement paste containing a powder component comprising -tricalcium phosphate (-TCP) particles having an average size greater than or equal to 9 m, and a liquid component comprising blood.

The present invention enables modification of an intraosseous implant device that is not only biologically non-inert, but can stimulate bone and vascular growth; decrease localized inflammation; and fight local infections. The method of the present invention provides a fiber with any of the following modifications: (1) Nanofiber with PDGF, (2) Nanofiber with PDGF+BMP2, and (3) Nanofiber with BMP2 and Ag. Nanofiber can be modified with other growth factors that have been shown to improve bone growth and maturationBMP and PDGF being the most common. Nanofiber can be applied on the surface of the implant in several ways. First, a spiral micro-notching can be applied on the implant in the same direction as the threads with the nanofibers embedded into the notches. Second, the entire surface of the implant may be coated with a mesh of nanofibers. Third, it can be a combination of both embedding and notching.

A method that includes the step of using a person's fingers to push a dental composition into engagement with a damaged tooth surface of a damaged tooth thereby adhering the dental composition to the damaged tooth surface and covering at least a portion of the damaged tooth surface. The dental composition includes a base material comprising at least one of the following compounds chosen from the group consisting of: a product consisting of one or more hydrocarbon-based waxes that may also include inorganic fillers and/or organic fillers; an uncured, uncrosslinked silicone high consistency rubber base; and a hydrophobic water insoluble solid material. The base material has a coating composition on one or more surface of the base material wherein the coating composition comprises: one or more desensitization ingredient and at least one dry, powdered hydrophilic polymeric substance.

A dental or bone material comprising a polysaccharide, diepoxide and calcium phosphate. The polysaccharide can be a chitosan, and the polysaccharide is modified to be soluble. The combination of the polysaccharide and diepoxide form a gel, which can be cured to form the implant. The curing does not require equipment, but instead the material is self-curing. Methods of making and using the material are also disclosed.

Compositions of, methods of making, and methods of using alkaline earth phosphate bone cements are disclosed. A bone cement composition includes a powder comprising a basic source of calcium, magnesium, or strontium, a setting solution comprising H3PO4 and a buffer, and a biocompatible polymer that is incorporated into the setting solution. The powder is mixed with the setting solution to form a bone cement paste that either (a) sets into a hardened mass, or (b) is irradiated with electromagnetic radiation to form dry powders, the dry powders then being mixed with a second setting solution to form a radiation-assisted bone cement paste that sets into a hardened mass.

Cellulose cyanoacrylate is employed to bond two surfaces, fill voids or duplicate the shape of a three-dimensional object, Two surfaces may be bonded by placing a sheet of cellulose material between the surfaces and applying cyanoacrylate glue around the edge of the sheet until saturated and allowing it to cure. Paper toweling may favorably be employed as the cellulose material. A break or fracture in an article can be overlaid with a sheet of cellulose that when saturated with cyanoacrylate glue and temporarily held in place and shaped with a releasable film, the fracture can be corrected. A dry powder comprising highly abrasion-resistant particles can be mixed with the cellulose material to enhance abrasion resistance and to improve long-term color stabilityespecially important for dental cavity treatment. To duplicate the shape of a three-dimensional object, a sheet of releasable film is placed over the object, followed by a sheet of cellulose that is then saturated with cyanoacrylate glue. A sheet of releasable film is then placed over the cellulose and used to hold the cellulose in place and shape it as it hardens.

A bone cement paste containing a powder component comprising -tricalcium phosphate (-TCP) particles having an average size greater than or equal to 9 m, and a liquid component comprising blood is disclosed. A method for preparation of the phosphocalcic cement composition is also disclosed.
