Objective To carry out the histological and histomorphometric plus radiological analysis of biphasic ceramic. Materials and method In this study, porous HA /β TCP (4Bone ® ) ceramic material was tested for the bone repairing capacity and osteoinductive potential in a New Zealand rabbit model. The ratio of the ceramic′s components HA /β TCP was 60/40 (in wt%). Results The 4Bone ® showed significantly more bone formation in the pores and in the periphery of the graft than the control group. Histomorphometric analysis revealed that the ceramic material (66.43% ± 0.29) produced higher values of bone‐to‐implant contact ( BIC ) percentages (higher quality, closer contact); moreover, defect closure was significative higher in relation with control group (64.15% ± 3.52). Conclusions 4Bone ® is a biocompatible, partially resorbable and osteoconductive grafting material. Biphasic graft material of HA /β TCP with a porosity of 95% without loading favors new bone formation.
