1. A dental implant system, comprising:
separate first abutment,
a separate second abutment, which is axially longer than the first abutment, and which is a replacement abutment for the first abutment,
a tooth implant where the first abutment or the second abutment attached by an attachment bolt, the tooth implant including:
an insertion section configured to anchor the tooth implant in a jawbone and provided with a screw thread or a nail thread,
a multi-functional section that is adjacent to the insertion section in a coronal direction, and that includes a first cone that tapers in the coronal direction,
an attachment section that is adjacent to the multi-functional section in the coronal direction, and that includes a second cone that tapers in the coronal direction so that the first cone and the second cone share a longitudinal axis and the second cone extends in the coronal direction from the first cone,
wherein the second cone is configured as a coronal protrusion,
wherein an external cone connection is provided at least between the second cone and the first abutment, and
wherein the second cone exclusively forms a seat for the first abutment, and
wherein the first cone and the second cone have an identical cone angle and are defined by a common smooth enveloping surface,
wherein the first abutment includes a first coronal end surface and the second abutment includes a second coronal end surface,
wherein the second coronal end surface of the second abutment is arranged relative to a coronal edge surface of the tooth implant where the first coronal end surface of the first abutment was when the first abutment is replaced by the second abutment,
wherein the second abutment extends in an axial direction of the tooth implant axis in an apical direction towards the jaw bone beyond the second cone into the first cone when the first abutment is replaced by the second abutment, whereby the second abutment contacts the tooth implant at least along a portion of the axial extension of the second cone and additionally at least along a portion of the axial extension of the first cone, so that the second abutment extends further towards the jaw bone than the first abutment.
