| Abstract: | BackgroundCritical size bone defect and fracture unable to regenerate itself, inspire the origination and technological advancement in the field of bone tissue engineering (BTE). The strategies of bone tissue engineering are often classified into three groups: First, is a direct injection of cells into the tissue of interest; second is grafting of cell-scaffold constructs; and third is scaffold-based signaling molecules, drug delivery or both. Much research was available on the first two categories, still finding the structure and property of scaffold close towards the natural tissue is yet to achieve.Aim of the ReviewThe proposed mini review focus on ceramic biomaterials uses for bone regeneration and drug delivery. It covers the fabrication process of scaffold including conventional and non-conventional i.e. rapid prototyping approach along with it advantage. The use of scaffold for drug delivery and signaling molecules such as growth factor is an emerging field of research in tissue engineering.ConclusionThe biodegradable beads used as a local drug delivery system are ubiquitous in surgery to treat post-operative infections but does not play any role in tissue regeneration. The use of this clinically accepted drug delivery technique in bone regeneration is an alternative way for the treatment on several bone infections (especially osteomyelitis and arthritis associated with tuberculosis). It is predicted to be the future of organ replacement and treatment. |
