Dental component, a dental fixture and a dental implant

A dental implant, comprising

• a dental component comprising a fixture engagement portion provided with
• at least one first indexing element having an apical end, and
• a plurality of neighboring second indexing elements having an apical end,
• a dental fixture adapted to be inserted into a jawbone and comprising
• a component engagement portion adapted to mate with said fixture engagement portion, the component engagement portion being provided with
• at least one third indexing element having a coronal end, and
• a plurality of neighboring fourth indexing elements having a coronal end,
• wherein the apical ends of the second indexing elements are located apically of the apical end of the first indexing element,
• wherein the first indexing element is only enabled to mate with the third indexing element after the second indexing elements has mated with the fourth indexing elements,
• wherein any play between the first indexing element and the mating third indexing element is smaller than a play between the second indexing elements and the fourth indexing elements, whereby a tighter fit is provided between the first and third indexing elements compared to the fit between the second and fourth indexing elements.

A dental implant comprising:

• a dental component including
• a fixture engagement portion for engaging the dental component with a dental fixture adapted to be inserted into a jawbone or for engaging the dental component with a fixture replica, the fixture engagement portion having a geometrical central axis and being provided with
• at least one radially projecting first indexing element having an apical end, and
• at least two neighboring radially projecting second indexing elements having an apical end located apically of the apical end of said first indexing element,
• wherein the radially most distant area of the apical end of the second indexing elements is located at a shorter radial distance from said central axis than the radially most distant area of the apical end of the first indexing element, or wherein the apical end of the second indexing element has, compared to the apical end of the first indexing element, a smaller dimension in the circumferential direction of the fixture engagement portion, and
• a dental fixture adapted to be inserted into a jawbone and comprising a component engagement portion adapted to mate with said fixture engagement portion, the component engagement portion being provided with
• at least one third indexing element having a coronal end, and
• at least two neighboring fourth indexing element having a coronal end,
• wherein the apical end of the second indexing elements is located apically of the apical end of the first indexing element and/or wherein the coronal end of the fourth indexing elements is located coronally of the coronal end of the third indexing element,
• wherein the first indexing element is only enabled to mate with the third indexing element after the second indexing elements has mated with the fourth indexing elements,
• wherein any play between the first indexing element and the mating third indexing element is smaller than a play between the second indexing elements and the fourth indexing elements, whereby a tighter fit is provided between the first and third indexing elements compared to the fit between the second and fourth indexing elements.
