Abstract: An improved dental prosthesis stabilizer includes two arms connected to each other by a hinge joint and with which an upper dental prosthesis and a lower dental prosthesis are coupled to one another. A spring is provided at the hinge joint with which the upper prosthesis and the lower prosthesis are pushed away from each other. At least one of the arms is telescopic and is formed of a bent distal end of the spring, which can be axially moved in a bent guide. The guide is fixed on the upper dental prosthesis or the lower dental prosthesis or is embedded therein.
