Claim 18:
19. 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 at least two external threads have a thread pitch of 2.0-2.5 or 2.8 mm;
said dental implant has at least two taps that extend from an apical end of said apical part to said coronal part while crossing said at least two external threads;
said apical part has a most apical region of said apical part, a middle region of said dental implant connecting said most apical region of said apical part and said coronal part of said dental implant;
said intra-bony coronal part has at least one external slot along external walls of said intra-bony coronal part, said external walls of said intra-bony coronal part are parallel to a central longitudinal axis of said dental implant;
an overall external diameter of said intra-bony coronal part being smaller than an overall external diameter of said apical part;
one of said at least two external threads has lateral tips, which are not crossed by at least one of said taps;
middle straight imaginary lines connecting all said lateral tips on both sides of an apical-coronal cross-section along said middle region of said dental implant have a first apically tapering angle;
and wherein apical straight imaginary lines connecting all said lateral tips on both sides of said apical-coronal cross-section along said most apical region of said apical part have a second apically tapering angle, said second apically tapering angle being larger than said first apically tapering angle.
