Abstract: A post-shaped element for determining the alignment of an implant (10), or the opening cross-section of an artificial indentation located in a tooth or in the stroma of a human or animal body, relative to the surrounding tissue structures, can be introduced with a receiving section (28, 26A) into an adapted receiving recess (10) in the implant (1) or the artificial indentation, and be affixed therein and removed again. In a connecting position the post-shaped element protrudes with a cantilever section (26K) beyond the opening cross-section of the receiving recess (10) or the artificial indentation.
