The article discusses the future of zirconia as a biomaterial, focusing on its aging process and its impact on long-term implant performance. Zirconia, a type of oxide ceramic, is known for its high mechanical strength and resistance to wear, making it a promising material for orthopedic implants. However, its susceptibility to aging, particularly in the presence of water, has raised concerns. The failure of Prozyr femoral heads in 2001–2002 highlighted the risks associated with zirconia aging, leading to a reevaluation of its use. The article emphasizes the need for advanced techniques to assess zirconia's aging sensitivity and the importance of modifying ISO standards to ensure the reliability of zirconia implants. It also discusses the development of alumina-zirconia composites as an alternative to monolithic zirconia, which may offer improved performance by mitigating the effects of aging. The study highlights the variability in zirconia's aging behavior based on processing and microstructure, and the need for more research to understand and control this process. The article concludes that while zirconia has potential, further advancements in materials science and standardization are necessary to ensure its safe and effective use in biomedical applications.The article discusses the future of zirconia as a biomaterial, focusing on its aging process and its impact on long-term implant performance.
