Dental implant and dental implant system

A dental implant, including an anchoring part extending between a coronal and an apical end;

• the anchoring part having an enossal portion shaped and equipped to be inserted into a cavity in bone tissue and having an enossal outer surface equipped to be in contact with bone tissue after implantation;
• wherein the enossal portion in at least one axial position includes a non-round cross section;
• the anchoring part having a coronally open cavity, the cavity extending at least through a part of the enossal portion and having an exit opening from an inside to the enossal outer surface;
• the implant further including an abutment;
• the abutment having a post protruding coronally, the post being equipped for fastening a crown or prosthesis to the dental implant;
• the anchoring part and the abutment being shaped for the abutment to be fastened to the anchoring part;
• the dental implant further including a thermoplastic element in a solid state,
• the thermoplastic element being arranged in the cavity or being introducible into the cavity,
• wherein the thermoplastic element is equipped to 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, so as to press at least a share of the flowable material of the thermoplastic element through the at least one exit opening into surrounding bone tissue on account of the pressing force, when the anchoring part is arranged in an opening in the bone tissue and the enossal outer surface is in contact with the bone tissue, so as to anchor, after re-solidification, the anchoring part in the bone tissue.

A dental implant system including:

• a dental implant anchoring part extending between a coronal and an apical end;
• the anchoring part having an enossal portion shaped and equipped to be inserted into a cavity in bone tissue and having an enossal outer surface equipped to be in contact with bone tissue after implantation;
• the anchoring part having a coronally open cavity, the cavity extending at least through a part of the enossal portion and having an exit opening from an inside to the enossal outer surface;
• the cavity having an apical thermoplastic material receiving section and a coronal abutment receiving section;
• the system further including a dental abutment;
• the abutment having a post protruding coronally, the post being equipped for fastening a crown or prosthesis to the dental implant;
• the abutment further having an apical anchoring post shaped to engage into the coronal abutment receiving section and to be fixed therein for the abutment to be fastened to the anchoring part;
• the system further including a thermoplastic element in a solid state,
• the thermoplastic element being arranged in the cavity or being introducible into the cavity,
• wherein the thermoplastic element is equipped to 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, so as to press at least a share of the flowable material of the thermoplastic element from the thermoplastic material receiving section through the at least one exit opening into surrounding bone tissue on account of the pressing force, when the anchoring part is arranged in an opening in the bone tissue and the enossal outer surface is in contact with the bone tissue, so as to anchor, after re-solidification, the anchoring part in the bone tissue;
• the system further including a protecting element equipped to prevent the flowable material from covering a surface of the coronal section so as to leave the coronal section free from any thermoplastic material of the thermoplastic element.
