A prosthesis is defined as an artificial device designed to replace a missing body part. This definition is fundamental within healthcare, particularly in the context of rehabilitation, as it allows individuals who have lost limbs or other body parts to regain functionality and improve their quality of life. Prosthetic devices can vary widely, ranging from artificial limbs to dental implants, helping patients adapt to their conditions and enhance mobility and independence. Understanding this term is crucial for healthcare professionals who must communicate effectively about patient care and rehabilitation options.
