Deproteinized bovine bone mineral (DBBM) and human freeze-dried bone allograft (FDBA) were compared in five patients undergoing bilateral maxillary sinus floor augmentation using DBBM on one side and FDBA on the contralateral side. After 9 months, core biopsy specimens were harvested. Mean newly formed bone values were 31.8% and 27.2% at FDBA and DBBM sites, respectively (P = .451); mean residual graft particle values were 21.5% and 24.2%, respectively (P = .619); and mean connective tissue values were 46.7% and 48.6%, respectively (P = .566). Within the limits of the present study, it is suggested that both graft materials are equally suitable for sinus augmentation.
对5例接受双侧上颌窦底提升术的患者进行了比较，一侧使用脱蛋白牛骨矿物质（DBBM），对侧使用冻干人同种异体骨（FDBA）。9个月后，获取核心活检标本。FDBA和DBBM部位新形成骨的平均比例分别为31.8%和27.2%（P = 0.451）；移植颗粒残留的平均比例分别为21.5%和24.2%（P = 0.619）；结缔组织的平均比例分别为46.7%和48.6%（P = 0.566）。在本研究的范围内，提示两种移植材料同样适用于窦腔增大术。
