Abstract: A variety of bone substitute materials can be used to repair and reconstruct clinical alveolar bone defects, but in the site with great bony volume insufficiency, it is very important to harvest and add a certain proportion of autogenous bone particles to achieve better clinical outcomes. The approaches to gain autografts include handheld instruments such as chisels and scrapers, rotating instruments such as trephines, piezoelectric instruments, and bone filters. It remains unclear which harvesting methods can provide autografts with the greatest osteoinductive and osteogenic potential in clinical bone augmentation. This review mainly summarized surgical results of different scholars using different methods of bone extraction from different sources of autologous bone, hoping to provide a reference for the selection of tools for bone extraction during clinical guidance of bone regeneration, to obtain the best bone induction effect and improve the quality of bone reconstruction.
