Core Viewpoint - Researchers at the Kant Baltic Federal University have developed a new composite material for repairing damaged bones, which accelerates bone graft recovery and improves patient quality of life [1] Group 1: Material Development - The composite material is designed to closely mimic the properties of human bone, addressing a significant challenge in medical research [1] - The material is based on biocompatible polymer polyether ether ketone, with the addition of 0.1% and 1% hydroxyapatite, forming a 2.5D scaffold composite [1] - This polymer is widely used in craniofacial and spinal segment surgeries, offering mechanical properties that are closer to bone tissue compared to metals [1] Group 2: Biological and Mechanical Properties - The 2.5D scaffold made from this composite material allows for the effective infiltration of active components into the regenerated bone tissue, enhancing its biological activity and regenerative capacity [1] - The incorporation of hydroxyapatite improves strength and cell viability, although a 1% concentration results in a reduced relative elongation [1] - The mechanical and biological properties of this composite material facilitate easy implantation into bone defect sites for reconstruction [1]
