Paste-like composition for dental use, and method for producing the same

A method for producing a paste-like composition for dental use that comprises a polymerizable monomer (A) and a filler (B), and in which the filler (B) comprises a particulate filler (B-1) having an average primary particle diameter of 0.001 to 0.2 μm, comprising:

• mixing the polymerizable monomer (A) and the particulate filler (B-1) having an average primary particle diameter of 0.001 to 0.2 μm to obtain an intermediate paste;
• and
• additionally mixing the polymerizable monomer (A) with the intermediate paste to obtain a final paste as the paste-like composition for dental use,
• the particulate filler (B-1) being mixed in an amount of 30 to 150 parts by mass relative to total 100 parts by mass of a total amount of polymerizable monomer (A) in obtaining the intermediate paste, wherein:
• polymerizable monomer (A) is at least one of a polymerizable monomer having a phosphoric acid group, a polymerizable monomer having a sulfonic acid group, a polymerizable monomer having a carboxylic acid group, a hydrophobic monofunctional polymerizable monomer having no acidic group, an aromatic bifunctional polymerizable monomer having no acidic group, an aliphatic bifunctional polymerizable monomer having no acidic group, and a tri- or higher-functional polymerizable monomer having no acidic group;
• the particulate filler (B-1) is not added to the intermediate paste during said additionally mixing to obtain the final paste;
• the final paste has a consistency of 15 to 40 mm;
• the particulate filler (B-1) contained in the final paste has an average secondary particle diameter of 20 μm or less;
• the intermediate paste has a consistency of 5 to 20 mm;
• and
• a content of polymerizable monomer (A) is 5 to 60 parts by mass relative to a total 100 parts by mass of the paste-like composition for dental use.
