因外伤、感染和肿瘤术后造成的牙槽骨损伤,经常需要植入骨或骨替代物。随着种植技术的日渐成熟,骨增量技术在种植修复中的应用越来越广泛,对骨替代材料的研究也越来越多。脱矿牙本质基质因其来源广泛,是近年来研究较多的一种骨诱导材料。本文就脱矿牙本质基质的分类、制备、作用、生物相容性和骨诱导机制作一综述。 Alveolar bone injuries caused by trauma, infection and tumor surgery often require the implantation of bone or bone substitutes. With the gradual maturity of planting techniques, the application of bone augmentation technology in implant repair is more and more widely, and more and more studies on bone substitute materials. Because of its wide range of sources, demineralized dentin matrix is ​​a kind of osteoinductive material that has been studied more in recent years. This article reviews the classification, preparation, function, biocompatibility and osteoinduction mechanism of demineralized dentin matrix.
