  • This object of the invention is achieved by the features in the characterizing part of claim 1. Due to the apparently simple but surprising finding that the denture can be moved exactly parallel to the chewing plane, the prosthesis automatically rests on the gums underneath over almost the entire area when a chewing force is applied to it, which means that most of the chewing occurs - And grinding forces are transferred to the gums and the jaw below.

This prevents the unintentional detachment of the artificial teeth from the holding part or the natural teeth mechanically.
