Abstract
Abstract A dental implant comprises a shaft having a smooth wheel of relatively large diameter on one end of the shaft and perpendicular to and coaxial with the shaft, and a plurality of relatively small wheels spaced along the shaft and spaced apart from each other and from the relatively large wheel. The relatively small wheels have each a cylindrical outer contour and have flanks that lie in planes parallel to each other and perpendicular to the axis of the shaft.
