Abstract
A self-tapping implant includes a shaft including a coronal end, an apical end, an outer surface having a first axial section and a second axial section, and a self-tapping configuration at the first 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. 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.
