摘要： The present invention provides a paste-form two-pack type dental curable composition having an adequate working time range and superior bond strength to dentin, in addition to showing small variation in working time, small decline in bond strength to dentin, and low risk of paste solidification over extended storage. The present invention relates to a paste-form two-pack type dental curable composition comprising: a first agent that comprises an acidic group-containing polymerizable monomer (A), an acidic group-free polymerizable monomer (B), an organic peroxide (C), a nitrogen atom-containing ligand (D), and a filler (E); and a second agent that comprises an acidic group-free polymerizable monomer (B), a thiourea compound (F), and a filler (E).

摘要： A monomer composition contains: a tin-free catalyst (A); and a (meth)acrylate monomer (D) that is a reaction product of an iso(thio)cyanate compound (B) and an alcohol compound (C). In this monomer composition, a content of an amide compound containing at least one of a carboxylic acid amide group or a sulfonamide group is less than 1 ppm by mass with respect to a total amount of the monomer composition.

摘要： [Object] To provide a dental adhesive composition that has high adhesiveness even to a silica ceramic restoration by containing a silane coupling material, can be stably preserved for a long period of time even with presence of both a silica filler and the silane coupling material, and is suitable as dental cement.
[Solving Means] A dental adhesive composition includes: 100 parts by mass of a polymerizable monomer component (A) formed of an acidic group-containing polymerizable monomer and an acidic group-free polymerizable monomer; 50 to 1000 parts by mass of a silica filler (B); and 0.1 to 20 parts by mass of a silane coupling material (C), in which 97 mass% or more of the silane coupling material (C) is an α-branched alkoxysilane silane coupling material formed of an organosilicon compound in which a monovalent radically polymerizable organic residue and a branched alkoxy group are bonded to a silicon atom, the monovalent radically polymerizable organic residue having at least one radically polymerizable functional group, the branched alkoxy group having 3 to 5 carbon atoms and a branch at an α position.-

摘要： The present invention provides a dental mill blank having an excellent mechanical strength and an excellent water resistance according to which a decrease in mechanical strength can be suppressed even in an environment where water is present, for example, inside an oral cavity. The present invention relates to a dental mill blank including: a polymer (A); and continuous inorganic fibers (B) that are oriented substantially in one direction, wherein the dental mill blank has a decreasing rate of 40% or less in three-point flexural strength after immersion in 70°C water for seven days.

摘要： The present invention provides a dental composition, suitable for use as a dental composite resin or other dental material, having good ease of handling, and that is highly stable in consistency and low in polymerization shrinkage stress while providing desirable mechanical strength and polishability for the cured product. The present invention relates to a dental composition comprising a polymerizable monomer (A), an inorganic filler (B), a prepolymer (C), and a polymerization initiator (D), the inorganic filler (B) having an average particle diameter of 1 to 20 µm, and a specific surface area of 10 to 300 m 2 /g. The prepolymer (C) preferably has a structure derived from the polyfunctional monomer (a). The polyfunctional monomer (a) has a molecular weight of preferably 250 to 1,000.
