富血小板纤维蛋白在上颌窦底提升术中作用的研究进展

A Review on Recent Progress of Platelet Rich Fibrin in Maxillary Sinus Elevation

上颌后牙区因其特殊的上颌窦解剖结构,易导致患者缺乏骨量而无法保持种植体稳定。通过上颌窦底提升术,在窦底黏膜与骨板间充填骨移植材料,可以有效增加可用骨高度,便于维持种植体长期稳定。富血小板纤维蛋白作为代替自体骨移植材料的血小板浓缩制品,具有源于自体、成骨作用好、制备方法简单、成本低廉等优点。本文就富血小板纤维蛋白在上颌窦底提升术中发挥成骨作用的研究进展作一综述。

The maxillary posterior region usually lacks sufficient bone mass and cannot support the implant.Through maxillary sinus floor lifting,the bone graft material is filled between the sinus mucosa and the bone plate,which can effectively increase the available bone height and keep the implant stable for a long time.As a platelet concentrate product instead of autogenous bone graft,platelet rich fibrin has the advantages of self-osteogenesis,simple preparation,low price,and so on.In this paper,the progress of platelet rich fibrin in replacing bone graft material for osteogenesis in maxillary sinus augmentation is reviewed.
