The commercial offer for bioceramic bone substitutes is very large, however, the prerequisites for applications in bone reconstruction and tissue engineering, are most often absent. The main criteria being: on the one hand physico-chemical features providing surgeons with an injectable and/or shapeable biomaterial; on the second hand the multi-scale bioactivity leading to osteoconduction and osteoinduction properties. In order to obtain greater suitability according to the nature of the bone defect to be treated, new bone regeneration technologies, ‘‘smart scaffolds’’ must be developed and optimize to support suitable Ortho Biology.
