The article presents classification of the thermosetting materials for bone augmentation. The physical, mechanical, biological, and clinical properties of such materials are reviewed. There are two main types of curable osteoplastic materials: bone cements and hydrogels. Compared to hydrogels, bone cements have high strength features, but their biological properties are not ideal and must be improved. Hydrogels are biocompatible and closely mimic the extracellular matrix. They can be used as cytocompatible scaffolds for tissue engineering, as can protein- and nucleic acid-activated structures. Hydrogels may be impregnated with osteoinductors such as proteins and genetic vectors without conformational changes. However, the mechanical properties of hydrogels limit their use for load-bearing bone defects. Thus, improving the strength properties of hydrogels is one of the possible strategies to achieve the basis for an ideal osteoplastic material.
本文介绍了用于骨增量的热固性材料的分类。综述了此类材料的物理、力学、生物学和临床特性。可固化骨整形材料主要有两种类型:骨水泥和水凝胶。与水凝胶相比,骨水泥具有高强度特性,但其生物学特性并不理想,必须加以改进。水凝胶具有生物相容性,能紧密模拟细胞外基质。它们可用作组织工程中细胞相容的支架,蛋白质和核酸激活结构也可如此。水凝胶可浸渍有骨诱导剂,如蛋白质和基因载体,且不会发生构象变化。然而,水凝胶的力学性能限制了它们在承重骨缺损中的应用。因此,提高水凝胶的强度性能是实现理想骨整形材料基础的可能策略之一。
