Comparative study on lateral maxillary sinus augmentation of without grafting, particle bone grafting and recombinant human bone morphogenetic protein-2+absorbable collagen sponge grafting with simultaneous dental implant placement: a retrospective s

Although particulate bone graft was effective for bone formation and space maintenance, no significant differences were observed in the implant survival rate or complications compared with the other methods. The sinus augmentation outcomes did not vary considerably regardless of the type of bone graft material used.
