Abstract (en)

[origin: DE19610715C1] The invention relates to a process for producing a bone substitute material from a high-porous ceramic block (10), which process is characterised in that a plurality of channels (20, 22, 24) are introduced into the ceramic block (10) and are filled with bio-resorbent polymer granules (30). The ceramic block (10) is subsequently heated to a temperature above the melting or flow temperature of the polymer granules (30). The invention also relates to a process for producing bone substitute material from a high-porous ceramic block (10), which process is characterised in that a plurality of channels (20, 22, 24) are introduced into the ceramic block (10) and are filled with bio-resorbent polymer material (30) which is either pourable or in the form of a preform. The ceramic block (10) with the polymer material (30) is subsequently treated with a substance or a substance mixture at high pressure under supercritical conditions, so that the thermoplastic synthetic material is flowable and/or mouldable.
