It is essential that the holding element, which may optionally be connected to a marking element, occupies a precisely reproducible position relative to the prosthesis part. For this reason, one has previously connected the metallic prosthesis parts with holding elements, which also consist of metal. However, it has been found that when handling the risk that the projections and recesses are damaged on the prosthesis parts by the patch on the projections and inserted into the recesses retaining elements.

A cet effet, il est prévu que les parties en retrait et en saillie coopérant avec des parties en saillie et en retrait correspondantes de l'élément de prothèse, situées sur l'élément de retenue, consistent en un matériau à déformation élastique. Les parties élastiques des parties en saillie et en retrait peuvent être contraintes sur l'élément de retenue par au moins un élément de serrage rigide disposé contre l'élément de retenue, contre les parties en saillie et en retrait de l'élément de prothèse. Le matériau à déformation élastique est une matières plastique. Un élément de marquage d'un système de navigation est fixé sur l'élément de retenue.
