The posterior maxillary segment frequently exhibits insufficient bone mass to support dental implants. Sinus floor augmentation enables implant placement in the posterior maxilla. This case series included ten sites, in which sinus floor elevation was done using sinus lift balloon system followed by augmentation utilizing irradiated cancellous bone allograft. Postoperative radiographic assessment of vertical bone gain was done at 3 and 6 months follow-up period. The mean initial and final bone height were 6.16 and 10.50 mm, respectively, with a mean increase of 4.34 mm at 6 months being observed with nil complication. The presented technique might represent a viable alternative for sinus elevation in posterior atrophied maxilla. Irradiated cancellous bone allograft can be advocated as an ideal bone graft material for sinus augmentation procedures.
上颌后段常常表现出骨量不足，难以支持牙种植体。上颌窦底提升术可使种植体植入上颌后部。该病例系列包括10个位点，其中使用上颌窦提升球囊系统进行上颌窦底提升，随后使用辐照松质骨异体骨进行增量。在术后3个月和6个月的随访期进行垂直骨增量的影像学评估。初始和最终骨高度的平均值分别为6.16 mm和10.50 mm，6个月时平均增加4.34 mm，无并发症发生。所呈现的技术可能是上颌后部萎缩区域上颌窦提升的一种可行替代方法。辐照松质骨异体骨可被推荐为上颌窦增量手术的理想骨移植材料。
