Researchers are currently developing new biodegradable metals to address the limitations of traditional implant materials. The goal is to create materials that support tissue regeneration and completely dissolve after the regenerative process has occurred. Additionally, it is important that the by-products of these materials can be metabolized by the body. Research has primarily focused on essential elements such as iron, zinc, magnesium, and their alloys. Zinc achieves excellent biocompatibility and corrosion properties making him a promising candidate for biodegradable devices (stents, screws, etc). However, pure zinc and its alloys suffer from poor mechanical properties (yield, ultimate strength and low-temperature creep at 37 °C). Improvements can be achieved by suitable alloying or the selection of various preparation techniques.
