Abstract
Titanium (Ti) and its alloys are widely used biomaterials in bone repair. Although these biomaterials possess stable properties and good biocompatibility, the high elastic modulus and low surface activity of Ti implants have often been associated with infection, inflammation, and poor osteogenesis. Therefore, there is an urgent need to modify the surface of Ti implants, where changes in surface morphology or coatings loading can confer specific functions to help them adapt to the osseointegration formation phase and resist bacterial infection. This can further ensure a healthy microenvironment for bone regeneration as well as the promotion of immunomodulation, angiogenesis, and osteogenesis. Therefore, in this review, we evaluated various functional Ti implants after surface modification, both in terms of static modifications and dynamic response strategies, mainly focusing on the synergistic effects of antimicrobial activities and functionalized osteogenic. Finally, the current challenges and future perspectives are summarized to provide innovative and effective solutions for osseointegration and bone defect repair.
钛（Ti）及其合金是骨修复中广泛使用的生物材料。虽然这些生物材料具有稳定的特性和良好的生物相容性，但钛植入体的高弹性模量和低表面活性往往与感染、炎症和成骨不良有关。因此，迫切需要对钛植入体的表面进行改良，通过改变表面形态或涂层负载来赋予其特定功能，帮助其适应骨结合形成阶段并抵御细菌感染。这可以进一步确保骨再生的健康微环境，并促进免疫调节、血管生成和骨生成。因此，在本综述中，我们从静态修饰和动态响应策略两方面评估了表面修饰后的各种功能性 Ti 植入物，主要关注抗菌活性和功能化成骨的协同效应。最后，我们总结了当前面临的挑战和未来展望，以期为骨结合和骨缺损修复提供创新而有效的解决方案。
