20090317780Tooth for Dental Arch Model and Method for Producing the Same - The present invention relates to a tooth which is used in a dental arch model with which dental students can experience dental works in the oral cavity and practice treatments. More specifically, the present invention relates to a tooth composition for formation trainings such as abutment tooth formation and cavity preparation. Since conventionally used dental arch models have a grinding sensation different from a natural tooth, dental students having completed formation trainings such as abutment tooth formation and cavity preparation by using these conventional models are frequently puzzled to have different grinding and handling properties upon dental works in the oral cavity in practice. That is, these conventional dental arch models are largely different from a natural tooth in grinding sensation including slipperiness and easiness in grinding. A tooth for a dental arch model simulating the enamel texture and the dentin texture constituting a natural tooth whereby even the difference in grinding sensation between the enamel texture and the dentin texture constituting a natural tooth can be reproduced by forming at least the enamel portion with the use of a sintered body of an inorganic powder such as alumina.12-24-2009
20090068614Dental polishing article which contains spherical resin particles - The present invention provides a dental polishing article having excellent polishability, which can polish dental composite resin, porcelain, dental restorative and prosthetic materials and teeth at a low cost, conveniently in a short time. More specifically, the present invention provides a dental polishing article which comprises a polishing portion formed by compounding polishing grains in an elastomer binder, and the polishing portion further comprising spherical resin particles.03-12-2009
20090048426POLYMERIZABLE PHOSPHONIC ACID DERIVATIVE AND ADHESIVE COMPOSITION COMPRISING THE SAME - The present invention provides an adhesive composition comprising a polymerizable phosphonic acid derivative which is a composition having intramolecularly a polymerizable group and a phosphonic acid group, represented by the general formula [1]:02-19-2009
20090048366Dental Composite Resin Cement, Dental Primer and Dental Adhesive Kit Containing Them - The present invention provides a dental resin cement which is excellent in a mechanical strength, workability and storage stability, and a dental primer which significantly improves adhesiveness of the dental resin cement both to enamel and dentin of a tooth. According to the present invention, a salt of barbituric acid is used as a polymerization initiator in the dual-cure two-paste type dental resin cement being excellent in workability and storage stability to improve the storage stability, and a primer containing barbituric acid and amine is applied to a surface of a tooth to significantly improve adhesiveness of the dental resin cement both to enamel and dentin of teeth.02-19-2009
