| 20080280263 | TRANSPARENT AND RADIO-OPAQUE RETENTION PIN - A dental retention pin made of composite material includes a core consisting of fibers embedded in a resin matrix. The fibers, which have a refractive index (n), are radio-opaque, and the refractive index (n′) of the resin forming the matrix has a value close to that of the fibers. | 11-13-2008 |
| 20090047635 | Isoelastic Endodontic Pin - An isoelastic endodontic pin for the long-term endodontic restoration of teeth is based on a single-piece, fibre-reinforced plastic base body having deformation zones and at least one zone designed in such a way that it possesses reduced flexural and torsional strength; displacement elements, preferably channels, for a fastening material are located outside these zones. | 02-19-2009 |
| 20090092950 | DENTIN ANCHOR - A fiber-reinforced composite (FRC) dentin anchor is disclosed comprising a coronal portion, to which a tooth restorative material may be secured, and a dentinal portion, adapted to be received in a pre-drilled hole in tooth dentin. The dentinal portion may be adapted to chemically bond to the tooth without the use of threads and the coronal portion may be adapted to chemically bond to a tooth restoration without the use of additional adhesives. The dental anchor may includes an intermediate portion having a shape and size that is different from the shape and size of the dentinal portion and the coronal portions and be adapted to be received entirely or partially within the pre-drilled hole in the tooth dentin. The modulus of elasticity of the dentin anchor may approximate the modulus of elasticity of tooth dentin. | 04-09-2009 |
| 20100068679 | Dental materials with a high flexural modulus - Low viscosity composites, with a flexural modulus of at least 18 GPa and a flexural strength of at least 90 MPa for filling dental root canals for fixing post or as a build-up material on post, are composed of aluminum oxide with a mean particle size of 1 to 50 μm in combination with at least one additional filler with a mean particle size of 0.5 to 5 μm and a monomer mixture. Also disclosed is a method for the preparation of tooth restorations. | 03-18-2010 |
| 20110250568 | DENTIN ANCHOR - A fiber-reinforced composite (FRC) dentin anchor is disclosed comprising a frusto-conical shaped coronal portion, to which a tooth restorative material may be secured, and a frusto-conical shaped dentinal portion, adapted to be received in a pre-drilled hole in tooth dentin. The dentinal portion may be adapted to chemically bond to the tooth without the use of threads and the coronal portion may be adapted to chemically bond to a tooth restoration without the use of additional adhesives. The modulus of elasticity of the dentin anchor may approximate the modulus of elasticity of tooth dentin. | 10-13-2011 |
| 20150305829 | REINFORCEMENT STRUCTURE FOR CORONAL-RADICULAR DENTAL RECONSTITUTION, METHOD FOR PERFORMING CORONAL-RADICULAR DENTAL RECONSTITUTION, CORONAL-RADICULAR DENTAL RECONSTITUTION - A structured reinforcement for a coronal-radicular dental reconstitution comprising:
