Zinc-based biodegradable implants have attracted noteworthy attention in the biomedical field due to their promising properties, such as biocompatibility, controlled degradation rate, and mechanical properties, which are suitable for load-bearing applications. This study includes other possible materials for biodegradable implants and why Zn is preferable over them by comparing their properties. Furthermore, areas where Zn is used as an implant are thoroughly explained. Various fabrication methods such as additive manufacturing, powder metallurgy, and casting are discussed in reference to optimise the structural integrity and degradation behaviour of Zn-based implants. The findings highlight the influence of fabrication methods on grain refinement, mechanical performance, and corrosion resistance, providing valuable insights into the development of next-generation biodegradable implants. The study further emphasises the need for tailored processing techniques to enhance implant performance for biomedical applications.
