A particulate alloplastic bone substitute material and method of making a free formed porous body

摘要

A particulate alloplastic bone substitute material comprising a plurality of particles, the particles having a core (1,11,21,31,51) and at least six pins (2,12,22) extending from the core (1,11,21,31,51) , 32, 52), wherein the pins (2, 12, 22, 32, 52) each have at least one connecting element (4, 14, 25, 34, 35, 37, 54, 57) and wherein the pins (2, 12, 52) 12, 22, 32, 52) are elastically deformable, so that by pressing together a plurality of particles, the connecting elements (4, 14, 25, 34, 35, 37, 54, 57) of different particles interlock with each other and / or snap and interlock with each other and or ruptured particles form an open-pore body of interlocked and / or ruptured particles.
