关于上颌窦底提升术骨增量策略的研究进展

上颌后牙区骨高度不足是种植手术常见的问题之一。而上颌窦底提升术拓宽了上颌后牙区种植的适应证。随着临床技术的进步和口腔材料学的发展，上颌窦底提升术的植骨策略不断更新。尽管上颌窦内的成骨机制尚未完全阐明，但上颌窦底提升术不植骨已经得到了越来越多的认可，如何选择和把握适应证是该策略的关键。经典传统的骨移植材料存在不同程度的缺陷，新型骨组织工程辅助材料应运而生，部分已得到临床应用。该文就上颌窦底提升术是否植骨、骨移植材料等方面的研究进展作一综述。

Research progress on bone augmentation strategy of maxillary sinus floor elevation

Deficiency of bone height in the posterior maxilla is one of the common problems in implant surgery. Maxillary sinus floor elevation expands indications for implanting in the posterior maxillary area. With the progress of clinical technology and the development of oral materials, the bone grafting strategy of maxillary sinus floor elevation surgery has been constantly updated. Although the mechanism of maxillary sinus floor osteogenesis has not been fully elucidated, there is increasing recognition of maxillary sinus lifting without bone grafting. How to select and grasp indications is the key to this strategy. Traditional bone graft materials have different degrees of defects. Therefore, new bone graft auxiliary materials emerge as the time requires, and some of them have been used in clinic. This paper reviewed the research progress on bone augmentation strategy of maxillary sinus floor elevation.
