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 called 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 such as bone grafting involve transplanting bone tissue to stimulate healing. Additionally, stem cell therapy is being researched for its potential to promote bone growth and repair, offering hope for patients with severe bone loss.
