The antonyms of artificial implants could be natural, biological or organic components. Natural implants are those derived from the patient's body or from other species, such as bone grafts, skin grafts, and animal valve replacements. Biological implants, on the other hand, refer to components created from living tissues, such as stem cells, which are used to regenerate or repair damaged organs. Organic components could refer to components that are made from entirely organic materials, such as plant-based materials, which are used in cosmetic surgeries, like fat transfer procedures. Using natural, biological or organic implants, when possible, can result in better patient outcomes, as the implants often integrate more seamlessly with the body and have fewer complications.
