A self-tapping dental implant includes a shaft including a coronal end, an apical end, self-tapping structure at the apical end, and an outer surface having a first axial section and a second axial section. The first axial section may be located coronally of the second axial section. Each of the first and second axial sections may include a series of peaks being axially spaced apart by troughs. In addition, the axial spacing between the adjacent peaks in the first axial section may be different than the axial spacing between adjacent peaks in the second axial section. Substantially all of the troughs in the first axial section may lie on an axial plane parallel to a main axis of the dental implant. Furthermore, the self-tapping structure may extend coronally from the apical end into the first axial section. A coronal end portion of the shaft may include the first axial section of the outer surface, and an apical end portion of the shaft may include the second axial section of the outer surface.
