prosthetic

A prosthetic is an artificial replacement for a body part that's missing or damaged. This could be a leg, arm, eye, or even a tooth.

Prosthetics are often used by people who've lost limbs in accidents or have been born with defects. For example, soldiers might use prosthetic legs after being injured on the battlefield, and athletes may wear prosthetic arms to improve their performance. Prosthetics can also be designed for everyday life, like hands that allow people to hold cups or grasp small objects. In some cases, people choose to have a prosthetic even if they're not medically necessary - it might just make them feel more confident or comfortable in their own skin.
