Alveolar bone is regenerated, usually using regenerative surgical methods such as block bone grafting and bone powder grafting. After periodontal bone grafting, alveolar bone defects are repaired through the formation of new bone by cells among the bone grafting material, the conversion of neighboring cells into osteoblasts by molecules in the bone grafting material, and the entry of cells from neighboring tissues into the bone grafting material. There are four main types of materials used in periodontal bone grafting: autologous bone, allogeneic bone, allogeneic bone, and non-bone grafting materials. The surgery requires high operation technique, so it is recommended to make sure to go to a regular hospital for the surgery. Regardless of which of the above materials are taken for surgery, it is necessary to review on a regular basis and pay attention to oral cleaning and plaque control. It is recommended that patients achieve correct and effective brushing after recovery from surgery, and also perform slight gum massage and extrusion to stimulate the alveolar bone; regular cleaning of root surface dirt and calculus is beneficial to the connection between periodontal fibers and root surface.
