A dental implant (1) includes a top section (17) and at least one top surface (7, 28) that is provided with a micro-roughened surface, such as an average roughness (RA) of about 0.7-1.1 µm, by etching. The top surface may include a porous surface of pore dimensions of less than about 10 µm or a coating, such as a 0.5 µm thickness of titanium nitride. The roughened surfaces promote healing in and tissue growth at the top, enhancing the sealing effect at the epithelium interface with the implant. |
