Dental molded product for milling and manufactual method thereof

摘要

Dental molded product for milling having excellent aesthetic quality, compatibility for machine and moldability from the moldable composition is provided. The dental molded product for milling is obtained by curing the moldable composition which includes a polymerizable monomer, a polymerization initiator, a first spherical inorganic filler and a second spherical inorganic filler. An average particle size of the first spherical inorganic filler is in the range of 0.2 to 10 μm. A content of the first spherical inorganic filler is in the range of 50 to 85 mass %. An average particle size of the second spherical inorganic filler is in the range of 0.005 to 0.1 μm. A content of the second spherical inorganic filler is in the range of 1 to 18 mass %.
