1-15. (canceled)
A process for manufacturing a composite biomaterial comprising at least one biocompatible resorbable organic polymer and at least one bioactive inorganic material,
- wherein said process comprises at least the following steps:
- i) compacting a powdery solid composition comprising at least one biocompatible resorbable organic polymer and at least one bioactive inorganic material with a compaction pressure of at least 2 MPa, so as to form a compacted solid composition, said biocompatible resorbable organic polymer being defined by a glass transition temperature Tg, and having a crystallinity degree of at most 30%,
- ii) sintering the compacted solid composition of step i) at a temperature Ts of at most Tg+70° C. and at a holding pressure greater than atmospheric pressure, so as to form a sintered solid, and
- iii) cooling the sintered solid.
A composite biomaterial as defined in 24, to support bone regeneration.
