Insertion part of a two-part implant with insertion instrument

摘要

The invention provides a method for inserting an insertion part of a two-part zirconium-like implant into the jawbone at high force without breaking in order in this way to increase the primary stability of the implant in the jawbone. This is made possible by providing an insertion part at the outside of two or more protrusions at the level of the jawbone line over which an insertion instrument with recesses fits which engages these protrusions in order to subsequently insert the insertion part into the jawbone. The sleeve-shaped insertion instrument with the recesses and the neck of the insertion part with the two or more protrusions can be shaped in such a way that they fit precisely together or that a connection resembling a cardan coupling is produced, so that the implantologist can hold the insertion instrument in various positions above the insertion part while the desired direction of insertion is still maintained.

主权项

1. A two part dental implant insertion system, comprising; a threaded zirconia insertion part adapted to be implanted in the jawbone, the insertion part being able to withstand an insertion force of at least 30 N-cm; and an insertion instrument for inserting the insertion part into the jawbone, wherein the insertion part includes a neck adapted to protrude above the jawbone, the neck including two or more round or oval protrusions disposed on a lower end of an outside wall of the neck, the neck including an annular segment having a curved profile, the curved profile corresponding in shape to an annular segment of a sphere and being disposed around the neck such that a diameter of the annular segment is more narrow at an insertion side of the insertion part than a diameter of the annular segment at an insertion instrument connection side of the insertion part, wherein the protrusions extend across an entirety of a height of the annular segment; wherein the insertion instrument includes a sleeve shaped upper rim that fits over the neck of the insertion part, the upper rim having recesses which are semi-circular for a fitting connection with the round or oval protrusions of the insertion part; and wherein the fitting connection between the insertion part and the insertion instrument functions as a cardan coupling.
