Particulate alloplastic bone replacement material and methods comprise a multitude of particles, whereby the particles comprise a core and at least six pins extending from the core, whereby the pins each comprise at least one connecting element, and whereby the pins are deformable elastically such that, upon multiple particles being pressed together, the connecting elements of different particles interlock with and/or snap into each other and the particles that are interlocked with and/or snapped into each other form an open-pored body of particles that are interlocked with and/or snapped into each other.
