Abstract
The use of bone graft particles for the preparation of a porous bone graft material including an acid containing self-setting adhesive composition. The bone graft particles have a porous core with an outer surface which is at least partially covered by an outer layer. The core includes a core material selected from the group consisting of an alloplast, a bone xenograft, and a bone allograft, or a mixture thereof. The outer layer of the particles includes a carbonate salt.
Claims16
A porous bone graft material produced by mixing bone graft particles with an acid containing self-setting adhesive composition, wherein:
- the bone graft particles include a porous core with an outer surface which is at least partially covered by an outer layer,
- the core comprises a core material selected from the group consisting of an alloplast, a bone xenograft, a bone allograft, and mixtures thereof, and
- the outer layer comprises a carbonate salt.
A method for preparing a porous bone graft material by mixing an acid containing self-setting adhesive composition with bone graft particles at the onset of curing, wherein:
- the bone graft particles comprise a porous core with an outer surface that is at least partially covered by an outer layer,
- the core comprises a core material selected from the group consisting of an alloplast, a bone xenograft, a bone allograft, and mixtures thereof, and
- the outer layer comprises a carbonate salt.
A kit for preparing a porous bone graft material comprising
- a) a first component A comprising an aqueous solution,
- b) a second component B comprising bone graft particles, and
- an acid containing self-setting adhesive powder that is present in the second component B or forms a third component C, wherein:
- said acid containing self-setting adhesive powder comprises at least a multivalent metal salt and phosphoserine,
- the bone graft particles comprise a porous core with an outer surface that is at least partially covered by an outer layer,
- the core comprises a core material selected from the group consisting of an alloplast, a bone xenograft, a bone allograft, and mixtures thereof, and
- the outer layer comprises a carbonate salt.
