\n\t\t\t\t\t\t\t\t\tWhat if bones could heal faster and stronger with the help of materials designed in a lab? Is this science fiction or the reality of orthopedic surgery today? Bone graft substitutes are changing fracture repair, spinal fusion, joint reconstruction, dental surgery, and many other surgical applications. Read on to learn more.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tBone regeneration is an amazing natural process; however, some conditions disrupt healing, making natural regeneration insufficient. Conditions such as avascular necrosis, nonunion and malunion fractures, and bone defects caused by trauma or tumors can significantly impair the body\u2019s ability to rebuild healthy bone tissue. When this happens, surgical intervention and bone grafting become essential tools to stimulate regeneration and ensure proper healing. Let\u2019s take a closer look at the world of bone graft substitutes (BGS) by exploring their types, advantages, limitations, and applications in modern fracture repair\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
