Element avsett att implanteras i kroppsvävnad samt förfarande och anordning för tillverkning av sådant element

摘要

The invention relates to an element (1) intended to be implanted in body tissue, especially bone tissue (3), which exhibits a controlled surface structure on at least that part (4A) of the implant (1) which is so arranged as to be in contact with bone. Both the surface and the form of that part (4A) of the implant (1) that is so arranged as to be in contact with bone (3) are produced in a common operation, so that the surface exhibits controlled isotropic surface topography, which gives high repeatability. The invention also relates to a method for the production of elements and an arrangement for that purpose.
