Dental implant and dental implant system

A dental implant, comprising:

• an implant body which extends between a coronal and an apical end and which defines an enossal outer surface,
• wherein the implant body comprises a coronally open cavity as well as at least one exit opening from an inside to the enossal outer surface, and
• a thermoplastic element in the solid condition,
• said thermoplastic element being arranged in the cavity or being introducible into this,
• wherein the thermoplastic element can be brought into an at least partly flowable condition by way of applying a pressing force which is directed apically into the cavity and mechanical oscillations and in this condition at least a share of the flowable material of the thermoplastic element can be pressed through the at least one exit opening into surrounding bone tissue on account of the pressing force, when the implant body is arranged in an opening in the bone tissue and the enossal outer surface is in contact with the bone tissue,
• wherein
• in an enossal region, the implant body comprises several roots;
• wherein the cavity or the cavities runs/run apically departing from the crown wherein the cavity has a non-rotationally symmetrical cross sectional shape, and the thermoplastic element has an outer cross sectional shape adapted to the non-rotationally symmetrical cross sectional shape of the cavity;
• and
• wherein the cross sectional shape of the cavity is multi-lobed, with one lobe present for each root.
