A mounting for an artificial tooth, which can be removed, has a rubber elastic retention ring (3) as the spring component of the structure. It is placed in the female section (2) so that it cannot slide axially and it is held without twisting when the male section (1) is inserted and removed. Its inner wall has a ventilation groove (15). The retention ring (3) is of plastics, and preferably nitrile rubber. The female section (2) is of titanium.
