Calcium phosphates have long been used as synthetic bone grafts. Recent studies have shown that the modulation of composition and textural properties, such as nano-, micro- and macro-porosity, is a powerful strategy to control and synchronize material resorption and bone formation.Biomimetic calcium phosphates, which closely mimic the composition and structure of bone mineral, can be produced using low-temperature processing routes, and offer the possibility to modulate the material properties to a larger extent than conventional high temperature sintering processes.Advanced technologies open up new possibilities in the design of bioceramics for bone regeneration; 3D-printing technologies, in combination with the development of hybrid materials with enhanced mechanical properties, supported by finite element modelling tools, are expected to enable the design and fabrication of mechanically competent patient-specific bone grafts.The association of ions, drugs and cells allows leveraging of the osteogenic potential of bioceramic scaffolds in compromised clinical situations, where the intrinsic bone regeneration potential is impaired.

磷酸钙长期以来一直被用作合成骨移植材料。最近的研究表明,调节成分和结构性质,如纳米、微米和宏观孔隙率,是控制和同步材料吸收与骨形成的有效策略。仿生磷酸钙紧密模拟骨矿物质的成分和结构,可以通过低温加工路线制备,并且比传统的高温烧结工艺更有可能在更大程度上调节材料性能。先进技术为骨再生生物陶瓷的设计开辟了新的可能性;3D打印技术,结合具有增强机械性能的混合材料的开发,并得到有限元建模工具的支持,有望实现机械性能良好的个性化骨移植的设计和制造。离子、药物和细胞的结合能够在临床情况不佳(即内在骨再生潜力受损)时利用生物陶瓷支架的成骨潜力。引用本文:Open Rev 2018;3 DOI: 10.1302/2058-5241.3.170056 。
