上颌窦底提升中骨增量材料的专家共识:自体骨

Expert consensus on bone grafting materials for maxillary sinus floor elevation:autogenous bone

自体骨来源于患者自身,具有骨生成、骨诱导和骨引导特性,且无免疫排斥和疾病传播的风险。因此,自体骨长久以来被视作骨增量材料的“金标准”。本文依据循证的原则,就骨增量材料的生物学特性、自体骨的获取、自体骨植入上颌窦底后的成骨过程和临床疗效以及自体骨的局限性进行总结,并依据国内部分专家的临床经验提出共识观点。

Autogenous bone is derived from the patient's own body and has osteogenic,osteoinductive and osteoconductive properties witho ut the risk of immunological rejection or disease transmission.For this reason,autogenous bone has long been regarded as the"gold standard"of bone grafting materials.This article summarizes the biological properties of bone grafting materials,the harvest of autogenous bone,the osteogenesis process and the clinical efficacy of autogenous bone graft in the maxillary sinus floor,and the limitations of autogenous bone,based on evidence-based principles,and proposes a consensus view based on the clinical experience of some Chinese experts.
