Design and manufacturing of biomimetic porous metal implants
Source abstract
Abstract
The stress-shielding effect can be minimized by using porous materials with pre-determined implant stiffness. This study aims to design interconnected porous metal implants that resemble the stiffness variations in a bone. Our design is intended to innovate mechanical loading conditions at the peri-implant bone, promoting a more robust implant–bone interface. The positional variations of stiffness in the scaffold are designed based on the Hounsfield Unit of computed tomography (CT) scan data of that location. Finite element (FE) analysis evaluates porous implants' performance compared to solid implants. Porous metal implants were additively manufactured with Ti6Al4V for compression test and reconstructed the 3D model from the micro-CT scan to validate the FE model. FE results revealed that porous implants generated a strain profile at peri-implant bone closer to normal bone irrespective of material property or anatomical location compared to solid implants.
