The upper convex surface of the core is in contact with at least part of the lower concave surface of the upper plate and the lower surface of the core is in contact with at least part of the upper surface of the lower plate. The upper plate is movable at least with respect to the core. There are cooperation means located opposite each other in the vicinity of edges of the prosthesis, between the lower plate and the core. These cooperation means limit translation movements of the core with respect to the lower plate along an axis substantially parallel to the lower plate, and to limit rotation movements of the core with respect to the lower plate, around an axis substantially perpendicular to the lower plate.2 2/4 24 20 23 C -24 20 - - - - - 23200 2 Figure 9a Figure 9b F 30 Front Rear 30 3 3 2 20 2 2 20 Figure 4a Figure 4b 202 20 3 2 Figure Sa Figure 5b
