Claim 21:
22. A dental implant comprising:
a body having a coronal part and an apical part that are continuous with one another, said apical part has a core and at least two external threads having a thread pitch of at least 1.5 mm extending along said core, said coronal part being located coronally to said at least two external threads, at least part of said coronal part being an intra-bony coronal part, an external surface of said intra-bony coronal part and an external surface of said apical part are both being a rough external surface configured to be in contact with bone;
said coronal part has a tapered socket becoming narrower apically for receiving a prosthetic element, apically to said tapered socket said dental implant has a first non-circular socket, apically to said first non-circular socket said dental implant has a second non-circular socket, apically to said second non-circular socket said dental implant has an internal thread;
said prosthetic element being fixated to said dental implant, said prosthetic element has a non-circular protrusion, said non-circular protrusion of said prosthetic element engages at least part of said first non-circular socket and at least part of said second non-circular socket so said at least part of said first non-circular socket prevents rotation of said prosthetic element and said at least part of said second non-circular socket prevents rotation of said prosthetic element;
wherein said coronal part has a coronal region and a most coronal part, said most coronal part of said coronal part extends coronally from said coronal region of said coronal part to a coronal edge of said coronal part;
said most coronal part of said coronal part has a cylindrical segment with one external diameter that extends coronally from said coronal region of said coronal part and being parallel to a central longitudinal axis of said dental implant;
said external diameter of said cylindrical segment of said most coronal part of said coronal part being smaller than an external diameter of said coronal region of said coronal part just apically to said most coronal part of said coronal part;
said coronal region of said coronal part has at least two external slots, said most coronal part of said coronal part consists of said cylindrical segment of said most coronal part of said coronal part and a most coronal segment;
and wherein an external surface of said most coronal segment of said most coronal part of said coronal part being tapered coronally forming said coronal edge of said coronal part.
