Demineralized bone matrix and cancellous bone chips in a reverse-phase medium carrier (DynaBlast, Keystone Dental) were used to augment the maxillary sinuses in 8 patients requiring 10 sinus augmentations. Clinical reentry after 6 to 7 months (mean, 6.2 months) and computed tomographic scan evaluation at 5 months demonstrated new bone formation as well as sufficient radiopaque volume to place implants in all sites. Microcomputed tomographic evaluation and histomorphometric analysis of sinus core biopsies confirmed the formation of new bone and demonstrated three distinctive mineralization patterns that have been previously described. DynaBlast can be considered a viable alternative to the use of autogenous bone or other types of grafting materials.
采用脱矿骨基质和松质骨碎片与反相介质载体（DynaBlast，凯斯通牙科）相结合的方式，对8例需要进行10次上颌窦增高术的患者进行上颌窦增高。6至7个月（平均6.2个月）后进行临床再入路，并在5个月时进行计算机断层扫描评估，结果显示所有部位均有新骨形成以及足够的不透射线体积以植入种植体。对上颌窦核心活检组织进行微计算机断层扫描评估和组织形态计量分析，证实了新骨的形成，并显示出三种先前已描述的独特矿化模式。DynaBlast可被视为自体骨或其他类型移植材料的可行替代物。
