钛金属具有良好的力学性能和弹性模量,抗腐蚀性好,生物相容性高,已逐步被应用于临床。钛金属及钛金属复合材料作为骨科替代材料适用于成骨细胞的外环境,不仅能提高植入材料与周围骨组织的整合性,还能增强成骨细胞的功能性,促进骨组织再形成。现就钛金属及其钛合金复合材料的生物相容性、生物力学性能等方面的研究进展及其在骨科中的应用进展予以综述。 Titanium has good mechanical properties and elastic modulus, good corrosion resistance, high biocompatibility, has been gradually applied to clinical. Titanium and titanium composite materials as orthopedic alternative materials for the outer environment of osteoblasts, not only can improve the integration of the implant material and the surrounding bone tissue, but also enhance the osteoblast function and promote bone tissue re-formation. Now on the titanium and titanium alloy composite biocompatibility, biomechanical properties of research progress and its application in orthopedics are reviewed.
