目前用于骨移植的金属人工骨与天然骨相比存在重量过大、弹性模量过高等问题。在这项研究中，三维（3D）自由成型钛网板骨移植应用被引入，以改善这些问题。通过三维CAD工具，从更高的柔性和强度的角度出发，在不同的基础形状和设计参数下设计基本网格形状和图案。根据设计的网格形状和图案，通过激光加工制造具有不同基底形状和设计变量的钛网板样品。对钛网样品的体积密度、拉伸弹性模量等拉伸性能进行了实验和分析评价。实验结果表明，这种钛网板具有更高的柔韧性，其力学性能可以控制到接近天然骨。钛网接骨板的力学性能，包括压缩、弯曲、扭转和耐久性，将在未来的研究中进行更多详细的研究。
Present metal artificial bones for bone grafts have the problems like too heavy and excessive elastic modulus compared with natural bones. In this study, three-dimensionally (3D) free-formable titanium mesh plates for bone graft applications was introduced to improve these problems. Fundamental mesh shapes and patterns were designed under different base shapes and design parameters through three dimensional CAD tools from higher flexibility and strength points of view. Based on the designed mesh shape and patterns, sample specimens of titanium mesh plates with different base shapes and design variables were manufactured through laser processing. Tensile properties of the sample titanium mesh plates like volume density, tensile elastic modulus were experimentally and analytically evaluated. Experimental results showed that such titanium mesh plates had much higher flexibility and their mechanical properties could be controlled to close to the natural bones. More details on the mechanical properties of titanium mesh plates including compression, bending, torsion and durability will be carried out in future study.
