Mechanical characterization of implant materials
Medical devices (e.g., implants made of biomaterials) play a crucial role in restoring human body functionality and curation of diseases. The main objective of the research in this work was in a comprehensive analysis, application and critical comparison of the methods of evaluation of mechanical properties of various biomaterials intended for clinical applications.
The focus of the experimental work is the dynamic mechanical analysis (DMA) based testing of biomaterials, aimed at closer mimicking of the physiologically relevant conditions for that specific biomaterial. Biomaterials including polymers, metals, and ceramics were studied using tailored DMA under different modes.
The findings of this thesis highlight the significance of the development and application of properly optimized protocols for the correct assessment of the biomechanical properties of biomaterials. This allows the characterization of the biomaterials and medical devices effectively, meeting the specific requirements of their intended clinical applications and compliance to the regulation such as EU MDR 2017/745. The results of the work directly contribute to the improvement of the design process and manufacturing of medical devices, benefiting patients and healthcare professionals alike.
