 Tissue engineered bone grafts have been developed to address the limitations of traditional bone grafts. These grafts combine a three-dimensional porous scaffold with osteoblast or progenitor cells to create a mechanically strong, biologically viable and degradable bone graft. Various materials have been used to construct these scaffolds, including ceramics, example, calcium phosphate, biocompatible slash bioactive synthetic polymers, example, poly, lactic acid, and more recently additive manufacturing techniques, example, fused deposition molding, stereolithography, selective laser sintering, inkjet 3D printing, laser-assisted bioprinting and 3D bioprinting. The scaffolds must possess certain mechanical properties to ensure their success in vivo. Additionally, the scaffolds must be able to survive the freeze-daw cycle, which is necessary for cryogenic preservation. Finally, the scaffolds must meet the regulatory requirements for tissue-engineered products. This article was authored by Harish Chenosamy, Mohankumar Day, and Ram Deviretti.
