Abstract
Official abstract text for this publication.
A dental polymerizable composition including a glass powder and a (meth)acrylate is provided. The glass powder includes zinc, silicon, and fluorine and is substantially free of aluminum.
First claim
Opening claim text (preview).
The invention claimed is: 1. A dental polymerizable composition comprising: a glass powder and a (meth)acrylate; wherein the glass powder includes zinc, silicon, and fluorine and is, substantially free of aluminum, and wherein zinc content, in terms of an amount of zinc oxide, ZnO, in the glass powder is in a range from 10 to 60 mass %; silicon content, in terms of an amount of silicon oxide, SiO 2 in the glass powder is in a range from 15 to 50 mass %; and fluorine content of the glass powder is in a range from 1 to 30 mass %. 2. The dental polymerizable composition according to claim 1 , wherein the zinc content, in terms of the amount of zinc oxide, ZnO, in the glass powder is in a range from 20 to 60%. 3. The dental polymerizable composition according to claim 1 , further comprising: at least one of calcium and lanthanum. 4. The dental polymerizable composition according to claim 1 , wherein the fluorine content of the glass powder is in a range from 1 to 6.8%. 5. The dental polymerizable composition according to claim 1 , further comprising: strontium, wherein strontium content, in terms of an amount of strontium oxide, SrO, in the glass powder is in a range from 0 to 12.4 mass %.
