Bone grafts are medical procedures used to repair and regenerate damaged or missing bone tissue. They involve the transplantation of bone or bone-like materials to stimulate the growth of new bone. These grafts can be obtained from the patient's own body (autograft), from a donor (allograft), or from synthetic materials (alloplastic). Bone grafts are commonly used in orthopedic and dental surgeries to treat fractures, non-healing bone defects, and bone infections, and to support dental implants. Bone grafting aims to enhance bone healing and restore functionality to the affected area.
