ABSTRACT:
A supporting mechanical connecting element of metal or the like high-strength material, preferably for the medical and dental field, is formed so that the connecting element and/or the receiving element is coated with a hydrolysis-stable bond-assisting layer undergoing a hydrolysis-stable chemical or physical-chemical bond with the material of the receiving element. In order to improve the mechanical retention the connecting element being used for anchoring has a cylindrical shaft, a circular portion conically tapering towards the free end and a circular, in cross section U-shaped recess extending from the free end inwardly, whereby this form is chosen so that it results in a tension reduction.
