summary:
The increase in orthopedic surgeries and the need for implants in increasingly younger patients are leading to more revision surgeries due to implant failure, largely due to the stress shielding effect. This project to design and manufacture a customized hip implant with Structures using additive manufacturing, which mimics bone stiffness, promotes osseointegration, and improves durability, thereby reducing complications and the need for reoperations.
Objectives
Reduce the stress shielding effect by design Structures with mechanical properties similar to those of bone, capable of adapting to the demands of the surrounding tissue.
To promote osseointegration using Structures optimized through a approach , by analyzing their ability to promote bone promote .
Increase the durability of the implant through post-processing techniques that extend the fatigue life of Structures manufactured by selective laser melting.
Improving the quality and precision of implants manufactured using additive manufacturing through hybrid manufacturing strategies and localized optimization of surface finish.
Design and manufacture custom hip implants by incorporating the strategies developed and validating their performance through comparative analyses with commercially available implants.
Key findings
development design criteria design mechanical characterization of additively manufactured Structures , enabling the stiffness of the implant to be matched to that of the bone tissue.
development a model to predict bone regeneration in Structures and optimize their design.
Analysis of the Effect of Heat Treatments on the Microstructure and Fatigue Life of Structures Ti-6Al-4V Structures .
development to optimize additive manufacturing parameters and combine additive and machining processes to improve precision and surface finish.
design hip implant prototypes with optimized Structures .
