The term osteoconduction applies to a three-dimensional process that is observed when porous structures are implanted into or adjacent to bone. Capillaries, perivascular tissues, and osteoprogenitor cells migrate into porous spaces and incorporate the porous structure with newly formed bone.
The osteoblasts are cells with a single nucleus that synthesize bone which in the process of bone formation function in groups of connected cells. The original definition of osteoinductive materials by Marshal Urist states that these biomaterials are capable of inducing bone to form when placed into an extraskeletal site. 5 Osteoinductive materials include autografts, demineralised bone matrix (DBM) and specific bone morphogenetic proteins (BMPs) which naturally form bone within the skeleton as well as extraskeletally 8, 10, 11 The ideal bone … osteoinductive, all material types, polymers, metals and both synthetic ceramics and ceramics of natural origin, theoretically possess the osteoinductive potential. Glass cylinders (Selye et al., 1960) and poly-HEMA (Winter and Simpson, 1969) were the fi rst synthetic materials associated with heterotopic bone formation and so far, poly-HEMA In recent years, commercial and experimental materials for bone repair, substitution, or augmentation have included metals, polymers, corals, CaP of natural (from corals or bovine bone) or synthetic origin, bioactive glasses (specially formulated silica-based glasses), and polymer and CaP composites. 4,5,22,26,30,34,45,48,51,69,71,84,85,95,98,124 The group of materials, which more closely approximate … With combinatorial approaches getting stronger to design materials with better functionalities and compatibility for restoring bone tissue, This chapter encompasses the journey of classes of biomaterials used for their osteoinductive and osteoconductive properties and discusses the challenges for bringing them closer to fulfil the requisites. N-Force Blue BSM is an injectable, self setting, macro-porous, osteo-conductive, calcium phosphate bone graft substitute material that is intended for use to fill bony voids or gaps of the skeletal system of the extremities, and the pelvis that are not intrinsic to the stability of the bony structure.
(A and B) Bio-Oss provides the body with a matrix for bone cell migration and is integrated into the natural physiologic remodelling process. Bio-active, osteoinductive and osteoconductive materials that are designed to promote bone growth in the implantation area. Used in critical size defects as bone grafts with complex inner patterns that mimic the surrounding bone's mechanical properties, and as custom ceramic implants in … 2016-11-24 Carbonate apatite structures are better osteoconductive materials than hydroxyapatite 3,4,5 Resorption and remodeling profiles are more similar to natural bone than those of synthetic materials, such as hydroxyapatite or tricalcium phosphate IN VITRO TESTING COMPARING GEM BONE GRAFT AND BIO-OSS X-ray Diffraction 1 The surface of BG has the ability to bound rapidly with the host tissue and this makes 45S5 Bioglass® a Class A bioactive material, such materials are both osteoconductive and osteogenic. Such material should be biocompatible, osteoconductive and porous as well as bioactive and compatible with the bone tissue. Subject of the work was investigations on nanocomposite membrane materials which consisted on synthetic polymer – poly-e-caprolactone (PCL) matrix and ceramic nanoparticles; tricalcium phosphate (TCP) and silica (SiO 2 ) as a nano-filler. • Osteoconductive materials merely act as a lattice or framework for cell growth, allowing osteoblasts from the wound margin to infiltrate the defect and to migrate across the graft.
The osteoblasts are cells with a single nucleus that synthesize bone which in the process of bone formation function in groups of connected cells.

Fig 13.1 Bio-Oss is a natural, osteoconductive bone substitute that promotes bone growth in periodontal and maxillofacial osseous defects. It consists of the mineral portion of bovine bone. (A and B) Bio-Oss provides the body with a matrix for bone cell migration and is integrated into the natural physiologic remodelling process. The osteoconductive properties of the new PEEK material were achieved by using a special functional additive - biphasic calcium phosphate - and allow bone cells to adhere to implants more quickly, thus positively influencing fusion, so called osteointegration, at the boundary between the bone and the implant. Bio-active, osteoinductive and osteoconductive materials that are designed to promote bone growth in the implantation area.

Osteoconductivity describes the property of graft material in which it serves as a scaffold for new bone growth but does not induce bone growth de novo. This means that osteoconductive materials will only contribute to new bone growth in an area where there is already vital bone.
