- 1 - ABSTRACT OF THE DISCLOSURE A joint for connecting a partial dental prosthesis to remaining natural teeth has a compression spring (1) acting on joint portions (1, 7) displaceable in a sagital direction, which spring relieves the prosthesis (13) connected to one of the joint portions (7) in the unstressed state. The displacement of the joint portions when the prosthesis is stressed is delimited by the stop surfaces (14, 15) in such a manner that the spring (10) cannot be completely compressed. This protects the spring and its functional capacity is permanently ensured and an optimal distribution of the biting and chewing pressure acting on the prosthesis over the anchor tooth (3) and the gums (6) is also attained.
