Bone regeneration is the process by which the body repairs and replaces damaged or lost bone tissue. This natural healing mechanism is crucial after injuries, fractures, or surgeries. The body utilizes specialized cells, such as osteoblasts, to form new bone and osteoclasts to break down old or damaged bone, maintaining a balance essential for healthy bone structure. In some cases, medical interventions may be necessary to enhance bone regeneration. Techniques like bone grafting involve transplanting bone tissue to stimulate healing. Additionally, advancements in tissue engineering and stem cell therapy are being explored to improve the efficiency of bone regeneration and treat conditions like osteoporosis.
