A preliminary evaluation consisted of a clinical examination, computed tomography (CT), and a panoramic x\u2010ray.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Ninety\u2010two patients requiring bilateral sinus grafts and 222 requiring unilateral procedures (total: 406 sinuses) participated in this study. A total of 1,025 implants were placed in the grafted sinuses. A total of 118 implants were placed simultaneously with the sinus graft (one stage), and 907 implants were placed in a subsequent surgery (two stages), 6 to 12 months after the graft was performed. In seven cases, a biopsy was harvested for histomorphometric analysis. Recall appointments were scheduled every 6 months, and panoramic and periapical x\u2010rays were required every year for 3 years.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Among 1,025 implants, 19 were lost (survival rate: 98.1%). The difference in survival rates for implants placed in native bone \u22643 mm (98.1%), &gt;3 to \u22645 mm (98.6%), and &gt;5 to \u22647 mm (97.0%) was not statistically significant (<jats:italic>P<\/jats:italic> = 0.3408). The survival rates for implants with rough and machined surfaces (98.6% and 97.0%, respectively) were not statistically significant (<jats:italic>P<\/jats:italic> = 0.0840). The histomorphometric analysis showed new bone formation (39.0% \u00b1 12%), marrow space (52.9% \u00b1 9.3%), and residual ABB (8% \u00b1 2.7%).<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Our results indicated that 1,025 implants placed in sinuses grafted exclusively with ABB combined with CM led to an excellent and predictable survival rate of
