medical ceramics such as alumina (Al₂O₃) and zirconia (ZrO₂) are advanced materials characterized by outstanding biological properties, most notably biocompatibility, which refers to their ability to integrate with body tissues without causing immune reactions or inflammatory responses. This characteristic has made them highly suitable for applications in prosthetic and orthotic engineering. These materials are particularly used in components subjected to high mechanical stresses and continuous friction, such as joint surfaces in prosthetic limbs, due to their high hardness and excellent wear resistance. Moreover, bioceramics contribute to improving the functional performance of prosthetic limbs, reducing pain, and enhancing the patient’s ability to achieve natural movement, thereby improving overall quality of life and mobility independence.
