Abstract
Official abstract text for this publication.
Disclosed are: a composition for hard tissue repair with excellent penetrability to an adherend such as a cancellous bone and excellent adhesion to an adherend, which comprises a monomer (A), a polymer powder (B) comprising 54% by mass or more of a polymer powder (b1) having a volume mean particle diameter of 27 to 80 μm and a polymerization initiator (C); and a kit for hard tissue repair comprising members in which the components of the monomer (A), the polymer powder (B) and the polymerization initiator (C) contained in this composition for hard tissue repair are encased in three or more divided groups in an optional combination.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition for hard tissue repair comprising a monomer (A), a polymer powder (B) comprising 54% by mass or more of a polymer powder (b1) having a specific surface area of 0.05 to 0.5 m 2 /g and a volume mean particle diameter of 30.5 to 80 μm, and a polymerization initiator (C), wherein the polymer powder (B) further comprises a polymer powder (b2) having a specific surface area of 0.51 to 1.2 m 2 /g and/or a polymer powder (b3) of particles having a specific surface area of 1.5 to 4.5 m 2 /g. 2. The composition for hard tissue repair according to claim 1 , further comprising a contrast medium (X) having a volume mean particle diameter of less than 3.0 μm. 3. The composition for hard tissue repair according to claim 1 , wherein the monomer (A) is a (meth)acrylate-based monomer. 4. The composition for hard tissue repair according to claim 1 , wherein the polymer powder (B) is a (meth)acrylate-based polymer powder. 5. The composition for hard tissue repair according to claim 1 , comprising 10 to 45 parts by mass of the monomer (A), 54.9 to 80 parts by mass of the polymer powder (B) and 0.1 to 10 parts by mass of the polymerization initiator (C) wherein the sum of the components (A) to (C) is taken as 100 parts by mass, and 0 to 70 parts by mass of the contrast medium (X). 6. A kit for hard tissue repair comprising three or more members, in which each of components of a monomer (A), a polymer powder (B) and a polymerization initiator (C) of a composition for hard tissue repair according to claim 1 are divided and contained in the members in an optional combination. 7. The composition for hard tissue repair as claimed in claim 1 , wherein the polymerization initiator (C) is an organic boron compound.
