Abstract

Official abstract text for this publication.

The present invention provides a dental curable composition used for dental filling restorative materials, dental crown prosthesis materials such as inlays, crowns, and bridges, materials for constructing anchor teeth, block materials for dental CAD/CAM, etc. More specifically, the present invention provides a dental curable composition comprising a curable resin (A), a porous inorganic filler (B), and a polymerization initiator (C), wherein the porous inorganic filler (B) comprises a silicon dioxide, and an oxide comprising at least one kind of the other metallic elements, and a ratio (I 1 /I 2 ) of a maximum absorbance (I 1 ) of 3730 to 3750 cm −1 to a maximum absorbance (I 2 ) of 3000 to 3600 cm −1 in infrared absorption spectrum of the porous inorganic filler (B), is not less than 1 and not more than 3.

First claim

Opening claim text (preview).

The invention claimed is: 1. A dental curable composition comprising a curable resin (A), a porous inorganic filler (B), and a polymerization initiator (C), wherein the porous inorganic filler (B) comprises a silicon dioxide and an oxide comprising at least one kind of the other metallic elements, and a ratio (I 1 /I 2 ) of a maximum absorbance (I 1 ) of 3730 to 3750 cm −1 to a maximum absorbance (I 2 ) of 3000 to 3600 cm −1 in infrared absorption spectrum of the porous inorganic filler (B), is not less than 1 and not more than 3. 2. The dental curable composition according to claim 1 wherein the at least one kind of the other metallic elements of said porous inorganic filler (B) are oxides containing at least zirconium element.
