The FOR5250 research group is developing a holistic solution for the production, characterization and simulation-based design of additively manufactured implants in dentistry, oral and orthodontics, taking into account the physiological conditions of the individual bone situation. In this funding period, the focus is on the long-term functionality of the implants. We at IKM develop a scalable material model that takes into account damage effects at different scales.
The high-cycle fatigue behavior is modeled for different numbers of load cycles at the micro level, while the lattice structure is examined at the meso level. The implant is then optimized at the macro level in terms of strength and morphology, with data transfer between the levels being performed by artificial neural networks. An efficient coupling of the scales is achieved using a novel homogenization approach and machine learning. To ensure adaptation to the individual jawbone, thermodynamic topology optimization is performed and the optimized permanent implants can be manufactured using additive manufacturing. A multi-scale algorithm helps to find the balance between structure and functionality.
