个性化钛网与传统网相比具有许多优势。关于钛网孔径和厚度对钛网力学性能的影响，文献报道很少。本研究旨在使用计算机辅助设计和增材制造技术开发个性化钛网。本研究还将通过三维有限元分析探讨不同厚度和孔径的钛网对其力学性能的影响。根据这项研究，钛网的机械性能随着厚度的减小（0.5 mm至0.3 mm）而增加。随着网眼直径的增加（3 mm ~ 5 mm），网眼的力学性能下降。钛网直径对其力学性能的影响小于钛网厚度。厚度为0.4 mm的钛网具有足够的强度，对粘膜的刺激较小，因此更适合临床使用。另外，钛网的参数应根据骨缺损的大小、部位和受力情况在临床上确定。
Individualized titanium mesh holds many advantages over conventional mesh. There are few reports in the literature about the effect of mesh pore size and mesh thickness on the mechanical properties of titanium mesh. This study is designed to develop an individualized titanium mesh using computer-assisted design and additive manufacturing technology. This study will also explore the effect of different thicknesses and pore sizes of titanium mesh on its mechanical properties through 3D FEA. According to this study, the mechanical properties of titanium mesh increased when the thickness decreased (0.5 mm to 0.3 mm). With an increase in mesh diameter (3 mm to 5 mm), the mechanical properties of mesh decreased. The diameter of titanium mesh has less influence on its mechanical properties than does the thickness of the mesh. Titanium mesh with a thickness of 0.4 mm is strong enough and causes less stimulation to mucosa; therefore, it is more suitable for clinical use. In addition, parameters of titanium mesh should be decided clinically according to bone defect size, defect location, and force situation.
