Abstract

Implant intended to be fixed through contact with new grown bone tissue comprising a dense material having an implant surface, and having, at least within a surface portion of the implant surface, surface pores covering at least 5% of the surface portion. The surface pores constitute a contact surface for new grown bone tissue, wherein close to at least a substantial fraction of all of the surface pores has at least one elevation extending over the implant surface which completely or at least partially surrounds an edge of the pore. Each elevation has a rough surface which causes formation of soft tissue when the implant surface is in contact with newly growing bone tissue.
