Name the alloys which are commonly used
The most commonly used alloys are Ti-6Al-4V and Ti-6Al-4V extra low interstitial (ELI). Commercially pure Titanium comes in different grades from CP Ti grade I to IV. The strength of CPTi is less than that of Ti-6Al-4V alloy, though the modulus of elasticity values is comparable. Ti alloys are able to maintain that fine balance between sufficient strength to resist fracture under occlusal forces and a lower modulus of elasticity for a more uniform stress distribution across the bone implant interface.
