A dental implant is provided having a longitudinal axis, and comprising an elongate body portion at an apical portion of the implant and a neck portion at a coronal portion of the implant. A first helical thread profile is around a first portion of the elongate body, at the apical portion. A second helical thread profile that is different from the first helical thread profile, is around a second portion of the elongate body that is between the first portion and the neck portion. The implant further comprises a third helical thread profile that is around the neck portion and that is different from both the first and second helical thread profiles.
