Metalurgical Advances in Titanium Implant Producturing

Historyczne, theniume implants were facilated from commercialle pure texium (Cp- Ti) or Ti- 6Al- 4V alloy using conventional machining and casting methods. While these materials offered acceptable performance, they presented limitations in osseointegration, elastic modulus matching, and customization. Recent advances in powder metalurgy, elecelectron beam melting, and selective laser singin have unlocked new possibilities for implant anne.
