Abstract
A dental catalyst for chemical polymerization comprising an acidic compound, an organic peroxide such as cumene hydroperoxide, and aryl borate compound such as sodium tetraphenylborate, but without substantially containing amine compound. This catalyst is chemically highly stable, is easy to handle, is highly active, is less likely to be impaired by polymerization, and does not cause the cured product to be tinted or discolored, and is very useful for the dental restorative.
Claims13
A dental catalyst for chemical polymerization comprising an aryl borate compound, an acidic compound and an organic peroxide, without substantially containing amine compound which exhibits a catalytic action.
An adhesive for directly restoring the teeth, comprising 100 parts by weight of a polymerizable monomer which contains an acidic group-containing polymerizable monomer as an acidic compound, 0.01 to 10 parts by weight of an aryl borate compound, 0.01 to 10 parts by weight an organic peroxide, 1 to 20 parts by weight of a multi-valent metal ion-eluting filler and/or 2 to 30 parts by weight of water, but without substantially containing amine compound as a catalyst.
An adhesive for indirectly restoring the teeth, comprising 100 parts by weight of a polymerizable monomer which contains an acidic group-containing polymerizable monomer as an acidic compound, 0.01 to 10 parts by weight of an aryl borate compound, 0.01 to 10 parts by weight an organic peroxide, and 50 to 900 parts by weight of a filler, but without substantially containing amine compound as a catalyst.
A dental restorative comprising 100 parts by weight of a polymerizable monomer, a catalytic amount of a dental catalyst for chemical polymerization of claim 1 and 50 to 900 parts by weight of a filler.
A dental pretreatment material comprising an acidic group-containing polymerizable monomer as an acidic compound, an aryl borate compound, an organic peroxide and water, but without substantially containing amine compound as a catalyst.
