| 20110300511 | FIBER-REINFORCED COMPOSITE POST - A fiber-reinforced composite post having an inner core section or rod fabricated of fibers impregnated in a resin matrix and an outer sheath of fibers arranged in the form of a mesh. The outer sheath comprises an interior and an exterior surface, the exterior surface is dry and unembedded fibers, and the outer sheath is attached to the inner core. In an embodiment of the dental post, the interior surface of the mesh is embedded in the resin matrix of the inner core with the inner core fibers. | 12-08-2011 |
| 20110171608 | SELF ETCH ALL PURPOSE DENTAL CEMENT COMPOSITION AND METHOD OF USE THEREOF - A self etching, dental cement composition is provided having the advantage of not requiring a separate etching and bonding step. The cement composition comprises a polymerizable (meth)acrylate trimellitic acid/anhydride, a phosphoric acid (meth)acrylate, a hydroxyalkyl(meth)acrylate, copolymerizable multi-functional (meth)acrylate monomers, a diluent, fillers, and a curing system. These cement compositions are prepared as a two-paste system that is combined prior to use. | 07-14-2011 |
| 20110129802 | DENTAL MATERIAL AND METHODS OF USE - A dental filling material comprising a polybutylene polymer having a molecular weight of about 10,000 to about 100,000 and being viscoelastic at about 20° C. The composition may include other polymeric resins, fillers, plasticizers and other additives typically used in dental materials. The filling material is used for the filing of root canals. | 06-02-2011 |
| 20100323330 | Tooth Colorant and Whitener, Method of Manufacture, and Method of Use Thereof - A polymerizable tooth colorant composition, comprising: a polymerizable resin composition; an additive composition comprising a colorant, a whitener, or both; and a curing system. The composition allows easy coloring and/or whitening of teeth. | 12-23-2010 |
| 20100292360 | Pre-Treated Acid-Reactive Fillers and Their Use in Dental Applications - A dental filler and dental resin restorative composition containing the dental filler is provided. The dental filler is prepared by pre-treating an acid-reactive filler with a polymerizable monomer or oligomer pre-treatment chemical having at least one acid or acid-precursor functional group, at least one polymerizable unsaturated carbon-carbon bond, and a molecular weight of about 1,000 grams per mole or less. | 11-18-2010 |
| 20100152019 | DENTAL RESIN MATERIALS, METHOD OF MANUFACTURE, AND USES THEREOF - A filler for a dental resin composition is disclosed, comprising silica particles derived from a nanoparticulate silica sol, the filler material having at least one crystalline phase. The filler material provides improved wear resistance and other properties. | 06-17-2010 |
| 20090246738 | Fiber Reinforced Composite Post - A fiber-reinforced composite post having an inner core section or rod fabricated of fibers impregnated in a resin matrix and an out sheath of fibers arranged in the form of a mesh. The sheath comprises an interior and an exterior surface, whereby the interior surface is attached to and embedded in the resin matrix of the rod and the exterior surface has dry, unimpregnated fibers. | 10-01-2009 |
| 20080250974 | Fiber-Reinforced Composite Dental Materials and Method of Manufacture - A dental material comprising a symmetrically rod-shaped fiber-reinforced composite comprising at least two layers of preimpregnated fibers, wherein the preimpregnated fibers comprise fibers coated with a resin, wherein the layers are unbraided, and wherein each layer is unidirectionally disposed on the preceding layer in a direction that is different from the direction of the preceding layer. The rod-shaped composite may be hollow and contain a channel throughout the axial length of the rod or may contain a shaft or other material that is inserted into the channel. | 10-16-2008 |
