Bone graft is the gold standard materials used for repairing bony defects. There are various bone graft materials/biomaterials and methods available for bone augmentation. The present article explains in detail about bone grafts and the recent advancements in bone graft materials as well as bone augmentation in implant dentistry.The literature search was performed for relevant articles on bone grafts for dental implants in PubMed/Medline, Scopus, Google Scholar, and Science Direct published in English literature published between January 2005 and March 2023. Relevant studies on bone grafts for dental implants were also included and critically analyzed in this review. Various biomaterials can be used to augment bone for implant placement. Each graft procedure has its own advantages and disadvantages in each clinical application and should choose the graft material carefully to attain a high success rate and less morbidity.
