in the tissue part and it is released after implantation in the cases of fig1 and 13 by way of a force with which the resonator is bent away or rotated off the implant 7 as an example of further fields of application for implants according to the invention fig1 shows the fixation of a cover plate 30 of bone or of a man made material into an opening of the calvaria 29 and the fixation for example of an artificial fixation plate 31 on a broken or fractured jawbone 32 similar applications are conceivable in reconstruction surgery in the facial region the connections that are to be created between the cover plate 30 and the surrounding bone tissue are advantageously limited to selected locations of the gap 33 between the plate and the native bone the fixation plate 31 is likewise connected to the jawbone at selected plate locations 31 u2032 the connections at the selected locations are realized in successive implantation steps using the implantation device 1 in section and in an enlarged scale fig1 to 17 show connections that may be created with implants 7 according to the invention and that for example are suitable for the applications shown in fig1 fig1 shows an implant 7 according to the invention that may be used to provide at least a local connection between the scull 29 and the cover plate 30 which is to be fixed in an opening of the.
