Abstract
A dental implant includes an implant body extending along a longitudinal axis between a coronal end and an apical end, the implant body having a core along which a helical threading having at least one thread extends. The dental implant includes at least one section in which the threading has a height which gradually decreases in the direction of the coronal end and in which the core is tapered in the direction of the apical end, the thread including an apical surface facing the apical end of the dental implant, a coronal surface facing the coronal end of the dental implant, and a peripheral lateral surface connecting the apical surface and the coronal surface of the thread. The apical surface of the thread has, in a cross-sectional view along the longitudinal axis, a first profile repeating according to an apical pitch. The coronal surface of the thread has, in a cross-sectional view along the longitudinal axis, a second profile repeating according to a coronal pitch. In one section, the apical pitch is greater than the coronal pitch.
