Bone regeneration is a treatment that grows new bone in weak jawbone regions by using another bone as a scaffold. This is required because when tooth roots no longer secure a piece of your jaw, the bone begins to degrade. Eventually, this may lead to tooth loss. Bone regeneration may be useful after traumatic injuries or diseases that leave holes in bones. It can also help prevent gaps from forming between teeth and surrounding tissues. During bone regeneration, blood vessels and lymph nodes are often damaged during surgery. Therefore, patients may experience pain, fever, and increased risk of infection. Long-term effects are dependent on the type of injury and what part of the body is being treated. In general, bone regeneration techniques produce good results over time. This process starts with removing any dead tissue around the injured area. Next, blood is drawn from the patient and placed in a centrifuge, where red blood cells are separated out. The remaining plasma is returned to the patient, along with platelets from a donor. Using this plasma, biocompatible materials that will encourage bone growth are mixed together to form a paste. This paste is then injected into the wound site through tiny needles inserted through the skin. As the bone regenerates, the wound will eventually heal itself without further intervention. In some cases, a membrane can be placed over the wound site to promote healing while keeping material from entering the mouth.
