In region 031 it is visible that a vestibular augmentation must take place. _Introduction The desire to use bone from your own body to build new bone in another place is almost as old as humanity itself. We call this procedure autolo- gous bone grafting. In the case of autologous bone grafting the boneisremovedfromthesameorganismthatthe graftistobeincorporatedin.Thebody’sownbone cells have the greatest potency for rebuilding of bones and are the gold standard in oral augmen- tation surgery. Donor areas are: the tuber maxil- lae, the retromolar space, the chin region or the iliac crest, the ribs or the shin. Gaining the re- quired quantity is sometimes elaborate (large surgical interventions, in patient stay) and af- flicted with particular problems, especially when it comes from regions far away from the oral cav- ity (e.g. the iliac crest). The extraction of autolo- gous bone grafts from the retromolar space find the best acceptance with patients. Particularlyinimplantologylateralaugmenta- tions are necessary in more than 75 per cent of cases. These augmentative measures mostly re- quire low bone volumes of less than 0.3 mg. If the decision is made intraoperatively, that the pa- tient’s own bone must be used, as a rule the fol- lowing question must be asked: “Which region should the bone be taken from and how can it be removed quickly?” Bone Harvesting— nice and easy Authors_Dr Steffen Hohl, Germany & Dr Anne Sophie Brandt Petersen, Denmark Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6
