Abstract: Autogenous bone grafting is a "classic schemes" to achieve sufficient bone in three-dimensional direction for dental defect sites with severe bone defect for intention of implant repair. The commonly used intraoral donor sites include chin and mandibular lateral oblique line. Compared with chin bone grafts, mandible lateral oblique line bone graft has less nerve complications, but compared with other alveolar ridge bone augmentation methods, the postoperative bone resorption rate is higher. This paper focuses on the mandibular lateral oblique massive bone grafts and its limitations, and describes other clinical widely used alveolar bone augmentation methods, comparing the changes of alveolar ridge width and height, postoperative bone resorption rate, and providing other bone augmentation methods to reduce the limitations of mandibular lateral oblique bone grafts.

Key words: mandibular lateral oblique massive bone grafts/autogenous bone graft/ bone resorption/ alveolar ridge bone augmentation
