Absorbing load comes from a material's ability to deform plastically under stress and distribute the force rather than fail abruptly. Ductility describes how much plastic deformation a material can undergo before fracturing, so a ductile metal like gold can bend and elongate slightly under implant loading. This deformation helps spread stresses over a larger area and through the surrounding structures, reducing the chance of sharp stress concentrations that could lead to crack initiation or failure at the implant-bone interface.

Hardness is about resisting surface indentation and doesn’t guarantee energy absorption; softness means the material deforms easily but not in a controlled, load-dispersing way; tensile strength measures how much tension a material can withstand before breaking, but it doesn’t describe how the material behaves as it deforms under load. Ductility specifically explains the load-absorbing, deformation-capable behavior that’s beneficial for implants.
