Title:
DENTAL COMPOSITE MATERIAL HAVING STABLE PASTE STATE
Document Type and Number:
WIPO Patent Application WO/2016/017582
Kind Code:
A1
Abstract:
A production method for a composite material that contains a filler, a polymerizable monomer, and a polymerization initiator, said production method being characterized by comprising the mixed polymerizable monomer preparation step, the silane treatment step, the silane-treated filler storage step, and the composite material production step that are described below. The mixed polymerizable monomer preparation step is a step in which the polymerizable monomer is mixed with the polymerization initiator in order to prepare a mixed polymerizable monomer. The silane treatment step is a step in which a silane treatment liquid having mixed therein 1 to 40% of a silane coupling agent and 99 to 60% of an organic solvent and/or water is prepared, the filler is inserted into a mixing container, and an amount of the silane treatment liquid corresponding to 1 to 15% of the silane coupling agent with respect to the filler amount is dripped into the mixture at a temperature in the range of 1 to 60 °C for a mixing time of 1 minute to 24 hours in order to produce a silane-treated filler. The silane-treated filler storage step is a step in which the silane-treated filler that has been subjected to silane treatment is stored for 30 to 600 days. The composite material production step is a step in which the mixed polymerizable monomer and the silane-treated filler are mixed in order to produce the composite material.
