The surface of a cylindrical, conical or stepped tooth implant has numerous groove-shaped recesses along its lengthwise axis or at a sharp angle to it. An alternative embodiment provides crosswise groove-shaped recesses at a sharp angle. In another embodiment, the surface of the implant body is divided along its lengthwise axis into numerous sections or steps that are separated by radial bands or transitions. The sections or steps have numerous groove-shaped recesses in their perimeter that follow the lengthwise axis of the implant body or run at a sharp angle or crosswise at a sharp angle. To create the tooth implant, a cylindrical, conical or stepped implant body with a smooth surface is preformed by creating groove-shaped recesses in a material-removing process. The material removing process is advantageously carried out with a digitally-controlled laser beam.
