Abstract
The invention relates to a dental implant comprising a shaft region (14) facing an apical end, comprising a base form that is substantially cylindrical or tapers down toward the apical end. The shaft region (14) is intended to be anchored in the bone of the patient in the implanted state. The dental implant further comprises a head region (12) adjacent to the shaft region (14) and facing a coronal end opposite the apical end. The shaft region (14) comprises an anchor region (20) disposed in the region of the apical end and a transition region (22) adjacent to the anchor region (20) and extending to the head region (12) in the coronal direction, wherein the boundary between the transition region (22) and the anchor region (20) extends 2 to 5 mm apical to the boundary between the head region (12) and the shaft region (14), and the surface structure of the transition region (22) is different from the surface structure of the anchor region (20).
