摘要/Abstract

摘要： 目的研究不同孔隙率及梯度孔隙率Gyroid结构力学性能,设计并制备新型多孔种植体。方法通过MSLattice和Magics软件建立均一孔隙率为60%、65% 、70% 、75% 、80% 和60%~80% 梯度的Gyroid结构模型,分别通过有限元分析及力学压缩试验对比不同孔隙率Gyroid结构力学性能,设计并通过激光选区熔融技术（selective laser melting, SLM）3D打印新型多孔种植体。结果随着孔隙率的上升,Gyroid结构的弹性模量和抗压强度下降。同一孔隙率下,SLA前后Gyroid结构的弹性模量差异不具有统计学显著性（P>0.05）,梯度Gyroid结构的最大抗压应变均低于各均一孔隙率Gyroid结构。结论梯度Gyroid结构匹配了骨皮质及骨松质的弹性模量,且强度与人骨相近,具有优异的力学性能,有望应用在口腔种植体上。

Abstract: Objective To study the mechanical properties of Gyroid structures with different porosity and gradient porosity, and to design and prepare a new type of porous implant. Methods Gyroid structure models with homogeneous porosity of 60%, 65%, 70%, 75%, 80% and 60%~80% gradient were established by MSLattice and Magics software. The mechanical properties of Gyroid structures with different porosity were compared by finite element analysis and mechanical compression test respectively. A new porous implant was designed and fabricated by selective laser melting (SLM). Results As the porosity increases, the elastic modulus and compressive strength of the Gyroid structure decreased. At the same porosity, the differences in the elastic modulus of the Gyroid structures were not statistically significant (P>0.05), and the maximum compressive strengths of the gradient Gyroid structures were lower than those of the homogeneous porosity Gyroid structures. Conclusion The gradient Gyroid structure matches the elastic modulus of cortical bone and cancellous bone, and the strength is similar to that of human bone, which has excellent mechanical properties and is expected to be used in dental implants.
