Optimizing Torp Middle Ear Prosthesis Material Performance Using FGM Material Degradation Approach

The advancement of technology in the field of human health plays a significant and positive role, particularly in the realm of hearing. In this study, we propose a novel approach for middle ear prostheses. We constructed a finite element (FE) model of the ear with a pure titanium TORP prosthesis, which we validated using experimental results. Subsequently, we applied the FGM (material degradation) method to alter the prosthesis material, utilizing biocompatible materials that can be used as hearing prostheses. We found that steel and hydroxyapatite ceramic can be used as alloys with titanium, and even customized prostheses can be manufactured according to patients needs.
