1. A specialist in providing manufactured dentures: Because Jane’s father needed a new set of teeth, a prosthetist skillfully inserted the new ones which he had designed himself.
2. A maker of artificial body limbs: The prosthetist measures, produces, adjusts, and services imitation external parts for the body; such as, a hand or a foot.
3. Someone who is engaged in the fabrication and fitting of diseased or missing sections of a person's physical structures: Because Nicole had a very bad bicycle accident, she lost one leg and a prosthetist was able to design and produce another one to fit her needs.
