Abstract
A screw implant for a jawbone has a conical threaded implant body with an implant neck and a conical implant post to accept a replacement tooth or a substructure. The thread of the implant body is a compression thread with concave thread turns. The implant neck preferably defines a bending zone wherein the ratio of the diameter D.sub.B to the length L.sub.B of the bending zone is in the range of 1:1.5 to 1:3. The bending angle is up to 30 degrees and the number of bendings of the bending zone is 3 to 4, when the implant post is bent back and forth. The implant neck has broadening transition sections.
Claims16
A screw implant for a jawbone comprising a threaded conical implant body adapted to be screwed into a jawbone,
