Metamaterials for implants
We apply the metamaterial concepts to modify the mechanical behavior of mandibular reconstruction plates - mandibular implants - to improve their longevity, osseointegration, and the quality of life of the patients.
We develop a computational framework to generate patient-specific “architected” implants by introducing fine-tuned porosity into clinically approved materials and applying state-of-the-art personalized implant design.
Using modern computational methods and patient-specific data, we aim to create implants with target mechanical behavior that can optimally match patients’ morphology and minimize the risk of failure and reoperations.

Our findings
1 / Understanding size effect in metamaterial implants
Metamaterials with carefully designed architectures can be used to create custom metal medical implants that last longer and reduce damage to surrounding bone. However, the size of the tiny repeating structures inside these materials can change how the whole implant behaves. In this study, we used computer simulations and experiments to see how changing this small-scale size affects strength and stiffness of the implant. Curious to know more? Read this paper.

2 / Multi-continuum homogenization
Traditional methods for predicting material behavior do not work well for small, structured materials because they ignore size effects. This study develops a new model that accounts for how tiny structural features influence overall stiffness. It shows material properties depend on both shape and actual size, improving design of advanced engineered materials. More details here.
3 / Topology optimization of implant microstructure
To appear soon.
