Abstract
Coated Prosthetic devices useful in the medical and dental fields, such as dental implants, intramedullary nails, and total hip prostheses, are provided having a porosity or density gradient in the sintered plastic coating. The higher porosity is at the outer surface which facilitates bone ingrowth while the lesser porosity which has a higher density and a more continuous plastic layer is on the inner surface and thus provides better adhesion to the load bearing component.
