Abstract
A dental implant includes an insertion portion which extends along an implant axis, and a coronal projection for receiving an abutment having a dental prosthesis formed thereon, which can be mounted on the dental implant with a screw. The insertion portion includes a coronal region and an apical region. The coronal projection extends from the coronal region of the insertion portion in the coronal direction and along a prosthesis axis. The coronal projection and the insertion portion are integrally connected in one piece. The prosthesis axis and the implant axis are inclined towards each other, and the abutment having the dental prosthesis formed thereon is attachable to the dental implant with only one screwing operation in the direction of the prosthesis axis.

A dental implant having:
- an insertion portion which extends along an implant axis, and
- a coronal projection for receiving an abutment having a dental prosthesis formed thereon, which can be mounted on the dental implant with a screw,
- wherein said insertion portion comprises a coronal region and an apical region, and
- wherein the coronal projection extends from the coronal region of the insertion portion in the coronal direction and along a prosthesis axis, wherein said coronal projection and said insertion portion are integrally connected in one piece,
- wherein the prosthesis axis and the implant axis are inclined towards each other, and the abutment having said dental prosthesis formed thereon is attachable to the dental implant with only one screwing operation in the direction of the prosthesis axis, wherein said coronal region is rotationally symmetric around the prosthesis axis and tapers in coronal direction, thereby enabling subtractive removal of an annular material region in the coronal region using a milling cutter that rotates about the prosthesis axis.
A dental implant having:
- an insertion portion which extends along an implant axis, and
- a coronal projection for receiving an abutment having a dental prosthesis formed thereon, which can be mounted on the dental implant with a screw,
- wherein said insertion portion comprises a coronal region and an apical region, and
- wherein the coronal projection extends from the coronal region of the insertion portion in the coronal direction and along a prosthesis axis, wherein said coronal projection and said insertion portion are integrally connected in one piece,
- wherein the prosthesis axis and the implant axis are inclined towards each other, and the abutment having said dental prosthesis formed thereon is attachable to the dental implant with only one screwing operation in the direction of the prosthesis axis,
- wherein in use, the insertion portion is to be inserted into the jawbone of a patient in such a manner that apposition of bone in the coronal region is enabled, and wherein said coronal region is rotationally symmetric around the prosthesis axis and tapers in coronal direction, thereby enabling subtractive removal of an annular material region in the coronal region using a milling cutter that rotates about the prosthesis axis.
